When you are talking of monitoring, you often end with many tools, like Nagios, Cacti or others. But none of them are interconnected.

There was a solution to add external pages inside Cacti, bythe aim of the Links plugin.

While migrating to Cacti 0.8.7a, I checked back the validity of this plugin with the new version. I ended with the new version : SuperLinks

This version adds many new things, like many tabs, authorization management and such.
As for now, the only problem I got is an error with the generation of the tab icon. I emailed the author about that.

On the same website, you will find the Weathermap plugins, which I still have to test with Cacti 0.8.7a.

[EDIT]

I got an answer from the author, and the bug is a known bug. It seems to be dependent of your config. You only have to add one line to the code. In the meantime, I also found a limitation in the URL size you can add, which wad 60. I set it to 512.

It wasn’t too long to upgrade cacti. Download files, patch with the plugins architecture, and there you go.

The good thing is that Cacti now knows how to bind to a LDAP directory with a user, search for your user, then authenticate. In fact, it seems they re-wrote the whole authentication system. You won’t have to apply my patch for that.

The bad thing is that the Threshold plugin patch is not yet working. But you know what ? I have an updated version working with the new cacti.

You will find it on the download page or here. Refer to the first post to know how to set it up.

The tools (network tools) plugins also have problems with the new snmp function of Cacti. I modified my patch, and I will send it to the author once again, and he may modify his stupid version with it. As a reminder, the patch, not only gives full compatibility with the new Cacti snmp code, but also add this crazy feature where you keep the informations you enter in each fields when you submit. Then you can submit a second time, or just change a parameter without having to re-enter every information. Did I said crazy ? Thanks the new Web 2.0 for this as everybody is doing
