Re: Status return nagios plugins using sed

http://nagios-plugins.org/doc/guidelines.html Piping into sed is going to overwrite the exit code that was returned by the check_icmp plugin. You're seeing "OK" because your final sed command in the chain is returning 0 for the exit code. Your Bash logic should include something to make su...

Re: Problems with disk size checks on Windows virtual machin

Which version of NSClient++ is running on the Windows VMs? It's going to influence how filters for your check_nrpe executions are written. Here's a thread from the customer support section in which lmiltchev offers some logic to filter out \\?\Volume records from the check_drivesize results: https:/...

Re: CRITICAL - Plugin timed out while executing system call.

A related thread: https://support.nagios.com/forum/viewtopic.php?f=7&t=44016 Nagios has some internal timeouts that apply to all plugin executions. SNMP is sloooowwwww. If your snmpget command takes longer than 60 seconds to return, you may be hitting the service_check_timeout limit, which trigg...

Re: WindowsEventID Monitoring

The solution is to either sign that script with an authority your system/organization likes, or to change the Powershell execution policy to allow unsigned (or remote signed) scripts to be executed: http://tritoneco.com/2014/02/21/fix-for-powershell-script-not-digitally-signed/ Here's more info in a...

Re: writing a plugin, looking for advice on capability or ot

Really sounds like you're looking for a custom event handler rather than a traditional Nagios plugin.

But yeah, all of that sounds very doable on a basic level and even something very typical of what people generally do with event handlers.

Re: Nagios core performance data

If you're willing to throw money at the problem, Nagios XI has pretty seamless integrations for performance data. Migrating from Core to XI is relatively painless: https://assets.nagios.com/downloads/nagiosxi/docs/Migrating-From-Nagios-Core-To-Nagios-XI.pdf If you're looking for something free, I'd ...

Re: Nagios core configuration managment

If you're looking for a paid, supported solution, there's nothing much better than Nagios XI . Nagios XI only manages a single core instance though, not multiple. Nagios Fusion can offer an overview of multiple Nagios Core/XI instances, but not consolidated management of all of those instances. For ...

Re: Template to carryout service check once every 4 seconds

I would strongly suggest creating this as a cron job or dedicated process/daemon instead, then submitting the results to Nagios Core as a passive check . Nagios Core wasn't really designed around this level of granularity. The interval Nagios Core uses is contained in the main cfg file as interval_l...

Re: Nagios XI: Scalability & data storage

Can somebody explain to me how Nagios XI can be scaled? The hardware requirements page is a good place to start: https://assets.nagios.com/downloads/nagiosxi/docs/Nagios-XI-Hardware-Requirements.pdf Strictly speaking, it depends. If you have 1000 checks that all require traversing entire SNMP trees...

Re: Nagios Core to Nagios XI

This process is pretty well documented and supported: https://assets.nagios.com/downloads/nagiosxi/docs/Migrating-From-Nagios-Core-To-Nagios-XI.pdf I'd recommend moving everything over to a completely new VM with a fresh installation of the latest Nagios XI version. Let us know if you encounter spec...
