Hi everyone, I installed the VMWare SDK to monitor a VMWare instance, as explained here in this document: https://assets.nagios.com/downloads/nag ... ios-XI.pdf

Shortly after installation, several physical server ping checks started failing! I have no idea how or why this occurred, does the SDK installation make any kind of networking/routing changes? Other devices on the same network seem fine...

I'm on Centos 7, and I completed all the necessary steps on the pdf up to getting the wizard working.

This is the check in question: $USER1$/check_ping -H $HOSTADDRESS$ -w 350.0,20% -c 500.0,60% -p 5

The SDK should have no effect.

Have you rebooted the Nagios XI server?

Have you tried the ping command from a command line to known working and non-working hosts?

Code: Select all

/usr/local/nagios/libexec/check_ping -H xxx -w 350.0,20% -c 500.0,60% -p 5

You should also look at using check_icmp, the commands are the same but it's faster:

Code: Select all

/usr/local/nagios/libexec/check_icmp -H xxx -w 350.0,20% -c 500.0,60% -p 5

Try enabling verbose mode (-vvv) to and show us the output.

Code: Select all

/usr/local/nagios/libexec/check_ping -H xxx -w 350.0,20% -c 500.0,60% -p 5 -vvv
