Adiscon is the company responsible for developping LogAnalyzer, a syslog (rsyslog, syslog-ng…) and/or flat file « analyzer ».
By analyzer, understand that it enables you to display the log in a meaningful way, splitting it depending on « views » and enabling real search filters.

If you don’t have the money for things liks Splunk and you are not convinces by other new projects using Rails, NoSQL and other tools that are a pain in the ass to install, you may fallback to LogAnalyzer.

Loganalyzer is a LAMP (Apache, PHP, Mysql) application. Installing it is as easy as putting the PHP files in you web Documentroot and browse to it. You will be asked a few questions and you can start importing your log files.

To do that you need to create « sources » of data. A source can now be a flat file on the local disk or a database (Mysql).
The choice for us was to use rSyslog on our servers. rSyslog is installed on every UNIX host. It is then configured to send the logs to a « loghost » server.
Additionaly, on some hosts, flat files like the Apache access_log or Error_log are also sent by rSyslog.
This lead to a client rsyslog.conf like :

On the server (receiver) side, the rSyslog will put data into files, rotating every day, and inside the DB.
Actualy I don’t know yet if it is a good idea. For the moment I keep everything. I may consider archiving the flat files and deleting old logs from the DB.
Then the DB would act as a buffer to search and correlate.

This is the server rsyslog.conf :

On the mysql side you will need to install the syslog-ng database schema. Mine is changed to also support ProcessID. (I will join the schema soon).
On the Loganalyzer side you need to define sources and views.
Sources will define which data source to use… flat file, mysql…
To be able to use Mysql you will need to also create (or use the provided) DBMapping. This will match the DB fields to the Syslog Fields.
Finaly, the « view » will decide which fields to display. For example, you could decide to display only the date and message of the error logs in a view because the hostname is not usefull. In another view you could decide that the date is not important but the host is, with the HTTP status code…

OK. You are all set-up with Loganalyzer… but you can only log-in with users from the mysql database.
My users are in LDAP.
While it would be hard to change the whole application to authenticate and search the groups in LDAP, the authentication part is easy to do.
I just changed the functions_users.php so, instead of looking the user in the DB, do the auth on LDAP, create the user in the DB and continue with the normal behaviour…

Here is the code of the new function in include/functions_users.php :

  1. function CheckLDAPUserLogin( $username, $password )
  2. {
  3. global $content;
  4.  
  5. $ldap_filter=‘(&’.$content[‘LDAPSearchFilter’].‘(‘.$content[‘LDAPUidAttribute’].‘=’.$username.‘))’;
  6.  
  7. // Open LDAP connection
  8. if (!($ds=ldap_connect($content[‘LDAPServer’],$content[‘LDAPPort’]))) {
  9. return false;
  10. }
  11. ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);
  12.  
  13. // Bind as the privilegied user
  14. if (!($r=ldap_bind($ds,$content[‘LDAPBindDN’],$content[‘LDAPBindPassword’]))) {
  15. return false;
  16. }
  17. // search for the user
  18. if (!($r=ldap_search( $ds, $content[‘LDAPBaseDN’], $ldap_filter, array("uid","cn","localentryid","userpassword") ))) {
  19. DieWithFriendlyErrorMsg( "Debug Error: Could not login user ‘" . $username . "’
  20.  
  21. <strong>Sessionarray</strong>
  22. <pre>" . var_export($_SESSION, true) . "</pre>
  23. <strong>Search Filter </strong>: " . $ldap_filter );
  24. return false;
  25. }
  26.  
  27. $info = ldap_get_entries($ds, $r);
  28. if (!$info || $info["count"] != 1) {
  29. DieWithFriendlyErrorMsg( "Debug Error: Could not login user ‘" . $username . "’
  30.  
  31. <strong>Sessionarray</strong>
  32. <pre>" . var_export($_SESSION, true) . "</pre>
  33. <strong>Search Filter </strong>: " . $ldap_filter );
  34. return false;
  35. }
  36.  
  37. // now we have the user data. Do a bind to check for his password
  38. if (!($r=ldap_bind( $ds, $info[0][‘dn’],$password))) {
  39. return false;
  40. }
  41.  
  42. // for the moment when a user logs in from LDAP, create it in the DB.
  43. // then the prefs and group management is done in the DB and we don’t rewrite the whole Loganalyzer code…
  44.  
  45. // check if the user already exist
  46. $sqlquery = "SELECT * FROM " . DB_USERS . " WHERE username = ‘" . $username . "’";
  47. $result = DB_Query($sqlquery);
  48. $myrow = DB_GetSingleRow($result, true);
  49. if (!isset($myrow[‘is_admin’]) ) {
  50. // Create User
  51. $result = DB_Query("INSERT INTO " . DB_USERS . " (id, username, password, is_admin, is_readonly) VALUES (".$info[0][‘localentryid’][0].", ‘$username‘, ‘rnd".md5(mt_rand()."rnd")."’, 0, 1)");
  52. DB_FreeQuery($result);
  53. $myrow[‘is_admin’] = 0;
  54. $myrow[‘last_login’] = 0;
  55. $myrow[‘is_readonly’] = 1;
  56. }
  57.  
  58. $myrowfinal[‘username’] = $info[0][$content[‘LDAPUidAttribute’]][0];
  59. $myrowfinal[‘password’] = "hidden";
  60. $myrowfinal[‘dn’] = $info[0][‘dn’];
  61. $myrowfinal[‘ID’] = $info[0][‘localentryid’][0];
  62. $myrowfinal[‘is_admin’] = $myrow[‘is_admin’];
  63. $myrowfinal[‘is_readonly’] = $myrow[‘is_readonly’];
  64. $myrowfinal[‘last_login’] = $myrow[‘last_login’];
  65.  
  66. return $myrowfinal;
  67. // Default return false
  68. return false;
  69. }
  70. function CheckUserLogin( $username, $password )
  71. {
  72. global $content;
  73.  
  74. // if auth LDAP is used, don’t check the DB yet
  75. if ( GetConfigSetting("LDAPUserLoginRequired", "") == "true") {
  76. $myrow = CheckLDAPUserLogin( $username, $password );
  77. }
  78. else {
  79. // TODO: SessionTime and AccessLevel check
  80. $md5pass = md5($password);
  81. $sqlquery = "SELECT * FROM " . DB_USERS . " WHERE username = ‘" . $username . "’ and password = ‘" . $md5pass . "’";
  82. $result = DB_Query($sqlquery);
  83. $myrow = DB_GetSingleRow($result, true);
  84. }

The rest of the code is the same.
Also I had to add some configuration entries in the config.php file

  1. // — LDAP auth options
  2. $CFG[‘LDAPUserLoginRequired’] = true; // activate LDAP auth
  3. $CFG[‘LDAPServer’] = "localhost"; // LDAP server hostname or IP
  4. $CFG[‘LDAPPort’] = 389; // LDAP port, 389 or 636 for SSL
  5. $CFG[‘LDAPBaseDN’] = "ou=my,o=ldap"; // Base DN for LDAP search
  6. $CFG[‘LDAPSearchFilter’] = "(objectclass=inetOrgPerson)"; // search filter
  7. $CFG[‘LDAPUidAttribute’] = "uid"; // the LDAP attribute used in the search to find the user. ex : uid, cn
  8. $CFG[‘LDAPBindDN’] = "cn=Manager,ou=my,o=ldap"; // DN of the privileged user for the search
  9. $CFG[‘LDAPBindPassword’] = ‘secret’; // Password of the privilegied user
  10. $CFG[‘LDAPGroupAttribute’] = ‘member’; // attribute used to search for groups
  11. // —

Here is the diff that you can put in a file and use the « patch » command to install.

It provides image galleries, albums with great ease of administration.
As said by the author, it fills a gap in WordPress gallery systems.

It can handle « display » templates, which can be added to the plugin Views or simply in your theme. That’s what I’m working on right now for the Photo Theme I’m using in my new Photo Blog.
This way you don’t have to install another plugin and use hooks.

While it’s working well, it still have some features missing.

One of the missing stuffs is beeing able to display GPS data.
My photo blog have Geo-Tagged pictures. I want to be able to display them along with a google map image so my readers can see where it was taken. I also want to display some of the EXIF informations, like lense type, aperture, shutter speed and so on…

While some of them (most) are already handeled by the NextGen gallery, some of them are not.
NextGen Gallery is using the exif_read_data function to get the data from the file like :

  1. $this->exif_data = @exif_read_data($this->image->imagePath , 0, true );

Then, the RAW exif datas are separated in arrays. When trying to access the EXIF tags (using get_EXIF), only the part of the array under [EXIF] will be used. In fact this is partly false, as the get_EXIF function also dig under IFD0 and WINXP.
As the GPS data from my Nikon D700 are under the [GPS] array, there is no chance that NextGen gallery sees them even if you use the wordpress filter to add some new EXIF tags.

Then you only have one solution : check in the RAW meta-data or… change NextGen so it can handle them in the EXIF tags stored in the database.

So, my solution is divided in few parts :

  • Hardcode some new EXIF tags
  • get the GPS data inside get_EXIF
  • add a function to parse the GPS data and make them readable/usable by Google Map

Let’s do it :

Hardcode some new EXIF tags

In the file lib/meta.php, change the get_common_meta function so it look like :

  1. function get_common_meta() {
  2.                 global $wpdb;
  3.  
  4.                 $meta = array(
  5.                         ‘aperture’ => 0,
  6.                         ‘credit’ =>  »,
  7.                         ‘camera’ =>  »,
  8.                         ‘caption’ =>  »,
  9.                         ‘created_timestamp’ => 0,
  10.                         ‘copyright’ =>  »,
  11.                         ‘focal_length’ => 0,
  12.                         ‘iso’ => 0,
  13.                         ‘shutter_speed’ => 0,
  14.                         ‘flash’ => 0,
  15.                         ‘title’ =>  »,
  16.                         ‘altitude’ =>  »,
  17.                         ‘longitude’ =>  »,
  18.                         ‘latitude’ =>  »,
  19.                         ‘timestamp’ =>  »,
  20.                         ‘datestamp’ =>  »,
  21.                         ‘satellites’ =>  »,
  22.                         ‘direction’ =>  »,
  23.                         ‘lense’ =>  »,
  24.                         ‘keywords’ =>  »
  25.                 );

As you can see, I add all the GPS data, plus « lense », which is just a hook as the EXIF tag for the lense is actualy « UndefinedTag:0xA434″

You can also add the new tags in the i8n translation function

  1. function i8n_name($key) {
  2.  
  3.                 $tagnames = array(
  4.                 ‘aperture’                      => __(‘Aperture’,‘nggallery’),
  5.                 ‘credit’                        => __(‘Credit’,‘nggallery’),
  6.                 ‘camera’                        => __(‘Camera’,‘nggallery’),
  7.                 ‘caption’                       => __(‘Caption’,‘nggallery’),
  8.                 ‘created_timestamp’ => __(‘Date/Time’,‘nggallery’),
  9.                 ‘copyright’             => __(‘Copyright’,‘nggallery’),
  10.                 ‘focal_length’          => __(‘Focal length’,‘nggallery’),

  36.                 ‘format’                        => __(‘Format’,‘nggallery’),
  37.                 ‘width’                         => __(‘Image Width’,‘nggallery’),
  38.                 ‘height’                        => __(‘Image Height’,‘nggallery’),
  39.                 ‘flash’                         => __(‘Flash’,‘nggallery’),
  40.                 ‘latitude’                      => __(‘Latitude’,‘nggallery’),

  43.                 ‘lense’                      => __(‘Lense’,‘nggallery’),
  44.                 );

get the GPS data inside get_EXIF

Now, every time you insert a new image or re-import the meta-data, the new tags will be asked. We need to change the get_EXIF function so it can find them.
Still in lib/meta.php, go down to the get_EXIF function and change it to  :

  1. function get_EXIF($object = false) {
  2.  
  3.                 if ( !$this->exif_data )
  4.                         return false;
  5.  
  6.                 if (!is_array($this->exif_array)){
  7.  
  8.                         $meta= array();
  9.  
  10.             if ( isset($this->exif_data[‘EXIF’]) ) {
  11.                 $exif = $this->exif_data[‘EXIF’];
  12.  
  13.                         if (!empty($exif[‘FNumber’]))
  14.                                 $meta[‘aperture’] = ‘F ‘ . round( $this->exif_frac2dec( $exif[‘FNumber’] ), 2 );
  15.                         if (!empty($exif[‘Model’]))
  16.                                 $meta[‘camera’] = trim( $exif[‘Model’] );
  17.                         if (!empty($exif[‘DateTimeDigitized’]))
  18.                                 $meta[‘created_timestamp’] = date_i18n(get_option(‘date_format’) . ‘ ‘ . get_option(‘time_format’), $this->exif_date2ts($exif[‘DateTimeDigitized’]));
  19.                         if (!empty($exif[‘FocalLength’]))
  20.                                 $meta[‘focal_length’] = $this->exif_frac2dec( $exif[‘FocalLength’] ) . __(‘ mm’,‘nggallery’);
  21.                         if (!empty($exif[‘ISOSpeedRatings’]))
  22.                                 $meta[‘iso’] = $exif[‘ISOSpeedRatings’];
  23.                         if (!empty($exif[‘ExposureTime’])) {
  24.                                  $meta[‘shutter_speed’]  = $this->exif_frac2dec ($exif[‘ExposureTime’]);
  25.                                  $meta[‘shutter_speed’]  =($meta[‘shutter_speed’] > 0.0 and $meta[‘shutter_speed’] < 1.0) ? ( ’1/’ . round( 1 / $meta[‘shutter_speed’], -1) ) : ($meta[‘shutter_speed’]);
  26.                                  $meta[‘shutter_speed’] .=  __(‘ sec’,‘nggallery’);
  27.                                 }
  28.                         //Bit 0 indicates the flash firing status
  29.                         if (!empty($exif[‘Flash’]))
  30.                                 $meta[‘flash’] =  ( $exif[‘Flash’] & 1 ) ? __(‘Fired’, ‘nggallery’) : __(‘Not fired’,‘ nggallery’);
  31.  
  32.                         if (!empty($exif[‘UndefinedTag:0xA434′]))
  33.                                 $meta[‘lense’] = $exif[‘UndefinedTag:0xA434′];
  34.             }
  35.  
  36.                         // additional information
  37.             if ( isset($this->exif_data[‘IFD0′]) ) {
  38.                         $exif = $this->exif_data[‘IFD0′];
  39.  
  40.                         if (!empty($exif[‘Model’]))
  41.                                 $meta[‘camera’] = $exif[‘Model’];
  42.                         if (!empty($exif[‘Make’]))
  43.                                 $meta[‘make’] = $exif[‘Make’];
  44.                         if (!empty($exif[‘ImageDescription’]))
  45.                                 $meta[‘title’] = utf8_encode($exif[‘ImageDescription’]);
  46.                         if (!empty($exif[‘Orientation’]))
  47.                                 $meta[‘Orientation’] = $exif[‘Orientation’];
  48.             }
  49.             // additional GPS information
  50.             if ( isset($this->exif_data[‘GPS’]) ) {
  51.                         $exif = $this->exif_data[‘GPS’];
  52.                         // send exif data to the function to get GPS on one line
  53.                         if (!empty($exif[‘GPSLatitudeRef’])) {
  54.                                 $GPS=self::get_Exif_GPS($exif, 1);
  55.                                 $meta[‘latitude’] = $GPS[‘latitude’];
  56.                                 $meta[‘longitude’] = $GPS[‘longitude’];
  57.                                 $meta[‘altitude’] = $GPS[‘altitude’]." metres";
  58.                                 $meta[‘timestamp’] = $GPS[‘timestamp’];
  59.                                 $meta[‘direction’] = $GPS[‘direction’];
  60.                                 if (!empty($exif[‘GPSSatellites’]))
  61.                                         $meta[‘satellites’] = $exif[‘GPSSatellites’];
  62.                                 if (!empty($exif[‘GPSDateStamp’]))
  63.                                         $meta[‘datestamp’] = $exif[‘GPSDateStamp’];
  64.                                 }
  65.             }

You can see two things here :
- if the meta asked is « lense », we look for the un-named attribute
- when we are done with EXIF and IFD0, we check in the GPS array

add a function to parse the GPS data and make them readable/usable by Google Map

Now we create the function to re-calculate the GPS coords. Create a function somewhere in the class. A good place is at the end of the lib/meta.php file, just before the last closing bracket.

  1. function get_Exif_GPS($exif, $assoc = false) {
  2.                 //get the Hemisphere multiplier
  3.                 $LatM = 1; $LongM = 1;
  4.                 if($exif["GPSLatitudeRef"] == ‘S’) {
  5.                         $LatM = -1;
  6.                         }
  7.                 if($exif["GPSLongitudeRef"] == ‘W’) {
  8.                         $LongM = -1;
  9.                         }
  10.  
  11.                 //get the GPS data
  12.                 $gps[‘LatDegree’]=$exif["GPSLatitude"][0];
  13.                 $gps[‘LatMinute’]=$exif["GPSLatitude"][1];
  14.                 $gps[‘LatgSeconds’]=$exif["GPSLatitude"][2];
  15.                 $gps[‘LongDegree’]=$exif["GPSLongitude"][0];
  16.                 $gps[‘LongMinute’]=$exif["GPSLongitude"][1];
  17.                 $gps[‘LongSeconds’]=$exif["GPSLongitude"][2];
  18.                 $gps[‘Altitude’]=$exif["GPSAltitude"];
  19.                 $gps[‘TimeHour’]=$exif["GPSTimeStamp"][0];
  20.                 $gps[‘TimeMin’]=$exif["GPSTimeStamp"][1];
  21.                 $gps[‘TimeSec’]=$exif["GPSTimeStamp"][2];
  22.                 $gps[‘direction’]=$exif["GPSImgDirection"];
  23.  
  24.                 //convert strings to numbers
  25.                 foreach($gps as $key => $value) {
  26.                         $pos = strpos($value, ‘/’);
  27.                         if($pos !== false) {
  28.                                 $temp = explode(‘/’,$value);
  29.                                 $gps[$key] = $temp[0] / $temp[1];
  30.                                 }
  31.                         }
  32.  
  33.                 //calculate the decimal degree
  34.                 $result[‘latitude’] = $LatM * ($gps[‘LatDegree’] + ($gps[‘LatMinute’] / 60) + ($gps[‘LatgSeconds’] / 3600));
  35.                 $result[‘longitude’] = $LongM * ($gps[‘LongDegree’] + ($gps[‘LongMinute’] / 60) + ($gps[‘LongSeconds’] / 3600));
  36.                 $result[‘altitude’] = $gps[‘Altitude’];
  37.                 $result[‘timestamp’] = $gps[‘TimeHour’].‘:’.$gps[‘TimeMin’].‘:’.$gps[‘TimeSec’];
  38.                 $result[‘direction’] = $gps[‘direction’];
  39.  
  40.                 if($assoc) {
  41.                         return $result;
  42.                         }
  43.  
  44.                 return json_encode($result);
  45.         }

Conclusion

Re-importing the meta-data of all your pictures should add the new stuffs.

I’v posted in the WordPress forum and asked for this to be added to the NextGen Gallery dev tree. Still have no answer for now. Maybe someone will come with a better code or better idea ?
I also asked for someone to check how GPS data are included in files from other brands as I can only tell for the Nikon’s D700.

It have unique features for DOM manipulation and web page animations. Another one is MooTools, said to be better in animations.

When you’re on a webpage with sliding images (orbit, novo slider…), growing windows or overlays… you can be pretty sure they are using one of these frameworks. The latest versions of WordPress bundle jQuery. As I wanted a special theme for my photo-blog (not yet finished but can be seen here), I had to dig in jQuery.

While the jQuery basis is really simple, somehow well documented on their website and full of examples on the net, you still have tricks to know so your code is 100% efficient, bug free and more important cross browser compatible (I mean, compatible with IE 6/7).

I will reference here the pages/people talking of such hints, tricks and notes, and maybe give my own recommendations and discoveries.

First one is actualy mine, even if it’s obvious : install Firebug or enable Safari Developper options in your browser. This way, just right-clic on a part of a webpage and « Inspect » it.
Most of jQuery scripts are in « full text », not minified or obfuscated. Or, at least, you will find clues of the author, the licence… and be able to use it, copy/modify it or just be insipred.

Second one is a must-read when you already know the basis of jQuery. It’s a 14 point tricks/notes from Jeffrey Way and located at http://net.tutsplus.com

They also have two other interresting articles about Hidden Features and Animation.

I would also like to add two blogs/website of people providing great examples and tutorials for free :

Sometimes you need to be able to send SMS from a computer. This is obvious when you’re talking of monitoring your servers. Email alerts are good, but what if you’re sleeping ?
I used to set up a SMS modem, with it’s own SIM card and subscription. This is really easy, using smsd daemon, to send SMS. Just put a formated file in a directory and bam!, you SMS is fired.
But what when you can’t set a SMS Modem in a datacenter ?

Then you have to use an online SMS provider.

  • Good

    • you just have to call an API to send a SMS

  • BAD

    • it’s not free (you pay per SMS when the modem can have an unlimited SMS sending subscription
    it is network dependant ; if you have a network failure, you will never be informed

    Once you know that, you can start using it.
    I will set up two monitoring plateforms : one inside the datacenter, monitoring every services and local network and one outside, on a hosted server somewhere else, to check the network connecivity of the datacenter.

    As our main monitoring is using Nagios, I had to write scripts for it. I now have 2 python scripts : one for sending SMS, one to check how many SMS I have on my account.

    I first had a quick look on the french SMS providers. I chosed www.smsenvoi.com as they are one of the cheapest and the http and mail API are free (yes, some providers make you pay for that !!). They are also based in Marseilles. I’m happy thinking people there can do better than people from Paris :)

    So, let’s dig the http API. You can find it at http://www.smsenvoi.com/pgs_api.php
    It’s quite simple, even if ugly : you send data in POST request, like : userLogin=your.account@domain.com&userPassword=your_password_clear&…
    And call a page, depending on your need :

    • smsEnvoi.php : send a message
    • smsNumber.php : see how many SMS you have availlable in your account
    • smsStatus.php and smsMNC.php : check if a SMS have been sent (this is used when you do mass sending)

    You can do pretty neat things. Just check on their website what the URL’s are.
    To be honest, I only re-write, in a simple way, what the PHP code do but in Python.

    You can find the two scripts attached.
    sendSMS.py take a message from the line input and send it. You have to start it for each recipient. Even if it’s easy to add many recipient at the same time, Nagios can’t do that. I’m just keeping it simple.
    check_sms_free is a script (nagios check formated) to check how many SMS you still have in your account. The Nagios check is defines to be at WARNING state when only 50 SMS are availlable and in CRITICAL state when only 10 are.

    Here are the Nagios config (I do have it in Nconf, but here is what is generated in the statis Nagios file) :

    1. define command {
    2. command_name                          host-notify-by-sms
    3. command_line                          /usr/bin/printf "%b" "Type: $NOTIFICATIONTYPE$ – Host: $HOSTALIAS$ – Address: $HOSTADDRESS$ – State: $HOSTSTATE$ – Date: $LONGDATETIME$ – Info: $HOSTOUTPUT$" | /opt/monitor/nagios/scripts/sendSMS.py –login=$USER8$ –passwd=$USER9$ –smsserver=www.smsenvoi.com –receivers=+$CONTACTPAGER$ –smsfrom=monitor-prod
    4. }
    5.  
    6. define command {
    7. command_name                          notify-by-sms
    8. command_line                          /usr/bin/printf "%b" "Type: $NOTIFICATIONTYPE$ – Service: $SERVICEDESC$ – Host: $HOSTALIAS$ – State: $SERVICESTATE$ – Date: $LONGDATETIME$ – Info: $SERVICEOUTPUT$" | /opt/monitor/nagios/scripts/sendSMS.py –login=$USER8$ –passwd=$USER9$ –smsserver=www.smsenvoi.com –receivers=$CONTACTPAGER$ –smsfrom=monitor-prod

    14. }

    Define the username and password for the smsenvoi account in resource.cfg as $USER8$ and $USER9$

    Then, you can add the check to a host :

    1. define service {
    2. service_description                   check_sms_free
    3. check_command                         check_sms_free!www.smsenvoi.com!50!10
    4. host_name                             localhost
    5. check_period                          24×7
    6. notification_period                   24×7
    7. contact_groups                        admins,sysadmins
    8. event_handler_enabled                 0
    9. active_checks_enabled                 1
    10. passive_checks_enabled                1
    11. notifications_enabled                 1
    12. check_freshness                       0
    13. freshness_threshold                   86400
    14. use                                   Default_timeperiod_interval_5
    15. }

    Don’t forget to define the cellphone number of each users in the « PAGER » field :

    1. define contact {
    2. contact_name                          @lecentre.net-sms
    3. alias                                  sms lecentre
    4. host_notification_options             d,r
    5. service_notification_options          c,r
    6. email                                 @lecentre.net
    7. pager                                 +33682887766
    8. host_notification_period              24×7
    9. service_notification_period           24×7
    10. host_notification_commands            host-notify-by-sms
    11. service_notification_commands         notify-by-sms
    12. }

    Note the format of the phone number, with international format, starting with +
    And voila…
    Find the two scripts here : sendSMS.py and check_sms_free

    Todos :
    - limit the message size to 160 caracters, which is the max for a single SMS. If you send messages longer, they will count as two SMS.
    - catch every exception in the httplib Python framework (this is really basic for the moment)

Here are things i’ve just found and needs a second look at, or more, a testing.

  • Human readable Glassfish Log

    • This is a shell (sh) script that should made things easier when having a look or doing a « tail -f » at Glassfish error logs.

  • Rajeshwar’s Weblog

    • This is a blog, lately talking about Glassfish V3 REST api implementation. As far as I know this is (still) not working with GF v2, which already have JMX and, if you’re a registered Sun user, SNMP. But worth having a look.

  • Beet

    • It seems to me that most of developpers are using Spring framework nowadays. This tool should enable them (or force them ?) to have a deeper look of what the framework is actualy doing. Seriously, comments welcome. May be the weapon of choice for sysadmins like me, dealing with developpers who hide behing their framework (like if the framework was an excuse… huhuhu).

  • PandoraFMS

    • Another monitoring software… well… to be tested.

  • Oracle Database-backed iGoogle Gadgets

    • An interesting thing you can do with Google’s API… It should with any database, but hey, a free software working with Oracle is worth beeing mentioned :)

  • Other Oracle related articles
  • Oracle TimesTen In-Memory Database

    • This is a PDF file dealing with TimesTen Database. This is a product newly (2 or 3 years) bought by Oracle, and well integrated. Embed the database close to the application, in the application server. Data are replicated at startup. You can choose which database, which table, which data using a filter, or even do transformations to the data. You select the synchronization frequency and there you go. I had a session OOW 2009 about that and how it was used to break a CDN application in two parts : one for slow data change (read/write to the DB) and one for massive fast queries on the delivery side. Ok, this use a lot of RAM… but RAM is cheap isn’t it ?

    Now we have some cool things to read and test, don’t we ? :)

    I tried to upgrade MacPorts… but I already had the latest.

    # port selfupdate

MacPorts base version 1.600 installed

Downloaded MacPorts base version 1.600

The MacPorts installation is not outdated and so was not updated
selfupdate done!

    I finaly found the solution on http://rob.cogit8.org/blog/2007/Nov/14/installing-django-leopard-mac-os-105/
