CRITICAL - Plugin timed out after 10 seconds

This error is coming from the check_by_ssh plugin. You could try increasing it's timeout with -t 30:

Code: Select all

/usr/local/nagios/libexec/check_by_ssh -t 30 -E 1 -l vi-admin -H 10.161.232.46 -C "~/box293_check_vmware.pl --server 10.161.232.50 --check vCenter_Name_Version"

However it shouldn't take that long to run.

I can see that you are testing as the nagios user, this is good. Can you confirm that you can establish a ssh session without being prompted for a password:

Code: Select all

su nagios
ssh [email protected]

Thanks Box293, after changing timeout to -t 30, plugin is working fine.

[nagios@auscrpmxxx root]$ /usr/local/nagios/libexec/check_by_ssh -t 30 -E 1 -l vi-admin -H 10.161.232.46 -C "~/box293_check_vmware.pl --server 10.161.232.50 --check vCenter_Name_Version"

Excellent, glad to hear it was a simple issue.

But now when I added vMA in vMA list on XI portal and tried SSH configuration vMA test , I get below message

The vMA host 10.161.232.46 is NOT in the known_hosts file.


Also let me know if on 1 XI server I am using more than 2 vMA servers, then do I need to generate different certificates? or is it ok if I can transfer same certificate on these 2 different vMA's?

Thanks

The same key should work on both servers, you'll want to copy it onto the VMA of 10.161.232.46 in order to get the SSH side of things working.

It's very important to follow these steps to make sure the SSH files are correctly implemented for the "VMware vMA Settings Manager".

VMware Virtualization Wizard - Installation Instructions.pdf

If you add multiple vMA hosts, you need to follow the "Configuration Steps REQUIRED" section each time you add another vMA host (basically you need to update the nagios SSH keys into the /var/www/.ssh/ folder).
