Nagios Support Forum

Hello Team,

We want to monitor CPU load for ISE servers and Barracuda web filters.
Could you please provide specific plugins for them?

Thanks in advance!!

See here for ISE:

https://labs.consol.de/nagios/check_nwc ... index.html
https://support.nagios.com/forum/viewto ... 16&t=58246

I think this will also work for the Barracuda:

https://labs.consol.de/nagios/check_nwc ... index.html

See here for some more Barracuda plugins:

https://exchange.nagios.org/directory/P ... /Barracuda

Let us know if you have any questions.

Thank you!

Hello,

Thanks for your help!!

That plugin is working fine for ISE servers.
For Baracudda, we are bale to fetch CPU load details, but when we cross verify it after logging into the device, the valur=e is not correct.

For eg: Nagios was showing 92% CPU load but actually it was just 42%.

Can you please help us to get the accurate values?

Were you using the check_nwc_health one or a different plugin for the barracuda? (link us to the exact one you're using if it's not check_nwc_health)

Please re-run the command from the XI server and send us the full output.

Hello,

We are using the standard check_nwc_health plugin only. Below is the command output for Baracuda 10.1.253.253.

I am attaching the screenshot of Baracuda dashboard here. If you see from screenshot, the system load is 6%. At the same time we checked from Nagios, it is giving system percent as 1.79%.

We are unable to understand why its giving different value?

[root@HO1-NAGIOSXI libexec]# ./check_nwc_health --hostname 10.1.253.253 --mode cpu-load --community mrtg#429monitor --verbose

More than likely the barricuda is doing this for their load calculation:

https://campus.barracuda.com/product/em ... +Firewall/

Based on the plugin it's likely just pulling the values that are returned to it by the remote device (and not doing the over time calculation), please send the output of these commands:
If those don't return anything, try these:

Hello,

Below is the output:

What is the full output of this command?
Looking at the code it looks like it's using this for calculations which seems to do the delta changes:

I'm unable to see what the issues is with the plugin, since this is a 3rd party plugin please create a new issue here so that the developer of it can fix it:

https://github.com/lausser/check_nwc_health/issues

I took a look but I was unable to find where the bug is.
