UNKNOWN: The node (/nfs) requested does not exist

[sneha.irali]

Hi Team,

I was able to poll the /nfs file system on this RHEL server however now I see this below error, what would cause this issue.

[[email protected] ~]$ /usr/local/nagios/libexec/check_ncpa.py -H 10.127.138.103 -t 'NagiosXI@Wintershall' -P 5693 -M 'disk/logical/|nfs' -w '80' -c '90'
UNKNOWN: The node (/nfs) requested does not exist. You may be trying to access the '/' node.

NagiosXI version : 5.8.5
RHEL (on which the agent is installed) : RHEL 8.3

Hello @sneha.irali

Thanks for reaching out, we see that the ncpa check on the gui is working but not from the command. Which makes us wonder if this is not related to permissions. (ls -l)

I see that you are checking using nagios as the user in the command, and would be curious to find out what happens if you run the check with root.

Please run the command with a verbose switch so we can see a bit more debug:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py --verbose --debug -H 10.127.138.103 -t 'NagiosXI@Wintershall' -P 5693 -M 'disk/logical/|nfs' -w '80' -c '90'

Let us know the results.

Thanks,
Perry

Hey,

This is to let you know that the customer has unmounted those FS in actual from the RHEL servers, hence we have those alerts.

Please let me know these will be remounted in future then how do I enbale them back since for now I have been asked to delete the /nfs File system from NAgios.

Hello @sneha.irali

Thanks for following up, if I understand correctly you want to stop monitoring the /nfs for the time being.

You can de-select the Active in > Core Configuration Manager (CCM).



Save and Apply Configuration.

Thanks,
Perry

[sneha.irali]

right.

But what if I delete it for now. How do I add it back is it that i will have to again run the wizard.

Hello @sneha.irali

You are correct, if you delete it you can add it again by running through the Wizard. Otherwise the option to de-select the Active in the configuration.

Thanks,
Perry
