Netflow integration with Nagios

Post by nets »

I need some help with integrating netflow tools such as Flavio, with Nagios. I am a new user, for linux and for nagios, so some detailed help will be highly appreciated. I downloaded the plugin that is required for the integration but I cannot figure out how to load or install that plugin into Nagios. Please HELP!!!!

Because of the huge amount of third party plugins that people write for Nagios, we're not able to document or test them all. We do have documentation on how to install third party plugins into XI. I did check this one, and it installs fine by uploading it from the XI web interface. As far as it's setup and usage, that varies depending on the plugin and author.

This is our general documentation for installing and setting up a third party plugin.
http://library.nagios.com/library/produ ... ng-plugins

I would try looking for more details from the author's website http://www.opsview.com/ and see what they have for documentation if you need more info.

Hope that helps.

I'm curious, for your use of NetFlow did you need the persistent nature of Flavio? It would be possible to feed netflow data into nagios via passive checks. The data would be graphed/archived using a Round Robbin Database. This years data for today replaces last years and last years is placed into a monthly average as the data from two years ago is compounded into a yearly average. This doesn't give you the ability to scroll backwards-in time the way flavio might, but you can look at a 50 year graph and see what the traffic for Jul was for the past ~5 years.

That is after 2 months you can see hourly stats, but the 1, 5, 10 and 15min stats are gone forever.

1. Add a command object, use the CCM(Core Config Manager).
2. Add a service to a host that makes use of the command.

It's hard to know how much guidance you'd need, but your task now is to read read read. One thing to look at is the output of the plugin and it's help documentation '--help' or '-h' flags.

I cant find any help with the plug in, I downloaded the plugin but there was no documentation with it. Is there any other place where I can find documentations for plugins?

Ahhem, The output of the check command it self. In the file it's lines 53 to about 105.

All of the check commands are documented this way instead of using manual or info pages. It's an acceptable practice as distributions that require these documents can create them from the commands output.
