Nagios Support Forum

Hi guys,

I've just added a vSphere ESXi host into the Nagios and Monitor a guest VM CPU/MEM/NETWOEK, and everything works fine with service "OK". I'm wondering how I can set up a threshold of the alert, e.g. if network traffic exceed 1Mbps, it should a alert of critical, not OK anymore.

Can you show us the actual command that you are running from the command line along with the output of it? You should be able to pass "-w" and "-c" flags for the warning and critical thresholds... This is from the plugin's help:

-w, --warning=THRESHOLD
Warning threshold. See
http://nagiosplug.sourceforge.net/devel ... HOLDFORMAT
for the threshold format.
-c, --critical=THRESHOLD
Critical threshold. See
http://nagiosplug.sourceforge.net/devel ... HOLDFORMAT
for the threshold format.

I suggest you try box293_check_vmware which can be downloaded here:
http://exchange.nagios.org/directory/Pl ... re/details

There is also a wizard for it:
http://exchange.nagios.org/directory/Ad ... rd/details

There are checks specifically for NIC usage (Host_pNIC_Usage).

Thanks @lmiltchev.
I'm running Nagios XI 5.2.3 with VMware wizard imbed. But wizard does't provide the threshold change. How can I show the CLI?

Thanks @Box293
Wondering whether the wizard support GUI threshold tuning？

@lmiltchev Just found it's using ESX3 plugin by Nagios XI 5.2.3 as the default VMware wizard. Any idea on how to set up the threshold?

Also I want to set up different threshold based on the service. e.g. I have two VM, for VM1, the bandwidth for critical threshold is 50%, for VM2, will be 20%, is this feasible?

Have you attempted to look at the service in the core configuration manager? You can change anything that was set up by the configuration wizard inside of there.

Yes, with every check available in the Wizard you can change the thresholds and the unit type as well (the plugin supports many different options).
