Link Close to Limit and Energy DownTime

[vsmori]

Hello Folks,

There's a Cacti installed in the company i work, monitoring routers. Most of then Cisco routers.

Somebody installed and configured Cacti there, but these people are not there anymore.

Everything is working fine.

I am working in one project, wich needs to get historical data to get two informations :

* Energy DownTime - Time spaces where there's no log, wich i can assume the router was off

* Internet Link close to limit available.

I assume i need to build a query, or something similar to get this data ... but i really was not able to understant Cacti terminology, probaly because i am not a network expert profissional.

Can someone help me understand how a query cacti to get these data?

regards,

Vitor

If you have plugins already set up (e.g. thold) then look at the Uptime plugin to find out if the router was really restarted or just that the line went down. You can get logs and an e-mail alert from this plugin. For Cisco equipment, you can tell the difference between a reload, power-off and a crash, too.

In fact, thold will solve the second issue - giving you an e-mail/syslog alarm when a data value goes above or below a threshold.

If you don't have plugins setup (look for the plugins/ folder inside the Cacti folder), then you would need to install the correct version of the Plugin Architecture for your version of Cacti. That could be difficult for older Cacti versions.

Version 0.8.7b
Plugins (Installed)
Cacti
Version: 0.8.7b
Plugin Architecture
Version: 2.1

Does it work for me?

[Howie]

Yes, if you install those two plugins as well.

For Uptime, see here

For thold, see http://cactiusers.org/

Great!

Do you see any chance of breaking the stability of Cacti ?

This is used as production monitor... if i install this, and crash it i will have problems.

Is there any way i can backup the current configurations, and in case of problems after installer, i could recover original configs?

Sure. Backup config.php/global.php.
Restoring the original will deactivate all plugins.
Nevertheless, it is better to setup a cacti test environment to get used to plugin arch; mostly any laptop will do
