How to monitor the mount point using NCPA agent

[IT-OPS-SYS]

hi team,

I am trying to monitor a mount point disk on one of my RHEL systems which has latest NCPA agent installed on it.
mount point is :/banapp

command used in the Nagios XI is below:

/usr/local/nagios/libexec/check_ncpa.py -H 149.24.41.83 -t 'token' -P 5693 -M 'disk/mount/|banapp' -D -v
Connecting to: https://149.24.41.83:5693/api/disk/moun ... lk&check=1
File returned contained:
{
"returncode": 3,
"stdout": "UNKNOWN: The node (/banapp) requested does not exist."
}
UNKNOWN: The node (/banapp) requested does not exist.

When I tried other partition, I am able to run this command to get the boot disk space as below:

/usr/local/nagios/libexec/check_ncpa.py -H 149.24.41.83 -t 'cFvgpWMXjaZojGlk' -P 5693 -M 'disk/logical/|boot' -D -v
Connecting to: https://149.24.41.83:5693/api/disk/logi ... n>&check=1
File returned contained:
{
"returncode": 0,
"stdout": "OK: Used disk space was 27.40 % (Used: 0.27 GiB, Free: 0.72 GiB, Total: 0.99 GiB) | 'used'=0.27GiB;;; 'free'=0.72GiB;;; 'total'=0.99GiB;;;"
}
OK: Used disk space was 27.40 % (Used: 0.27 GiB, Free: 0.72 GiB, Total: 0.99 GiB) | 'used'=0.27GiB;;; 'free'=0.72GiB;;; 'total'=0.99GiB;;;


M I missing anything or could you please provide me the way to monitor the mount point un my RHEL machine using the NCPA.

What are the outputs from the following commands (on the RHEL machine you want to monitor):

Code: Select all

mount
df -h

and i wanted to monitor the mount point /banapp on this RHEL machine. I am using NCPA agent on this machine.

That's an NFS mount. By default ncpa.cfg excludes NFS mounts. You'll want to un-exclude nfs mounts by editing ncpa.cfg and edit exclude_fs_types to not include nfs.

Then restart the ncpa listener process.
