Sadly, a Nagios Log server is already out of the budget for my environment (or else id be using Nagios XI instead of Core)

What about the check_nrpe built in CheckEventLog system? Is there an example syntax for monitoring this log using that?

Okay so root@glamon2:/usr/local/nagios/libexec# ./check_wmi_eventid.sh -H 192.168.60.41 -u mydomain/myusername -p mypassword -l 'Microsoft-Windows-Windows Defender%4Operational' -e 2000 -w 1 -c 3 -t1 -m60000 Select EventCode,EventIdentifier,EventType,SourceName from Win32_NTLogEvent where ( Logfile ...

Hi, So with my check_nrpe now working, I am trying to check my event log for a specific event for Windows Defender. I have tried 2 possible ways and both aren't meeting my demands. Firstly, I tried a custom plugin for nagions - check_wmi_eventid.sh. This was done purely because I was aware of it bef...

Final Update: My command parameter was wrong: root@glamon2:/usr/local/nagios/libexec# ./check_nrpe -H 192.168.60.41 -n -c CheckCPU -a warn=80 crit=90 time=20m time=10s time=4 OK CPU Load ok.|'20m'=2%;80;90 '10s'=2%;80;90 '4'=7%;80;90 I think that means case is closed? Unless anything else with the ....

Update: Possible Fix NSClient.ini here: nsclient.ini I changed ssl options = & verify mode = none and then on the Nagios server: root@glamon2:/usr/local/nagios/libexec# ./check_nrpe -H 192.168.60.41 -n I (0,4,1,73 2012-12-17) seem to be doing fine... However: root@glamon2:/usr/local/nagios/libex...

Any more help would be greatly appreciated.

I've tried changing some settings and hotswapping Scott's settings with my own and continually get the same errors. I've reverted back to my last post and still getting the same errors.

Sadly, just the same response:

Okay, thank you for your help by the way. So I reverted that change, restarted NSClient++ and ran: root@glamon2:/usr/local/nagios/libexec# ./check_nrpe -H 192.168.60.41 -p 5666 -n CHECK_NRPE: Receive header underflow - only 0 bytes received (4 expected). At least we are getting a new error now. But ...

Updated as requested - I did comment out your example password as my server isn't configured to use one: nsclient.ini On Nagios Server: root@glamon2:/usr/local/nagios/libexec# ./check_nrpe -H 192.168.60.41 -p 5666 CHECK_NRPE: (ssl_err != 5) Error - Could not complete SSL handshake with 192.168.60.41...

Changes were made to the nsclient.ini file as seen in here: nsclient.ini Then on Nagios Server (running an nmap just for demonstration purposes): root@glamon2:/usr/local/nagios/libexec# ./check_nrpe -H 192.168.60.41 -p 5666 -t 30 CHECK_NRPE STATE CRITICAL: Socket timeout after 30 seconds. root@glamo...
