Help needed to check filesize..Facing issue while uisng check_myfilesize.pl

[DileepKumar]

Hi,

I'm using Nagios XI 2026R1, I'm trying to monitor the filesize of a remote server using check_ncpa.py and check_myfilesize.pl(placed on client/remote server) but facing the below issue.

(Usage) : check_myfilesize.pl Filename critical_size warning_size

While trying from Nagios XI as below
./testncpa.py -H HOSTNAME -t TOKEN -M plugins/check_myfilesize.pl -a "/userdata/datastore/lib/config/datastore_007/msgs.db 10000000000 10000000000 "

error is as below which is wrong (In my opinion, it is not taking -a as one argument)
Argument "datastore" isn't numeric in numeric gt (>) at /usr/local/ncpa/plugins/check_myfilesize.pl line 37.
Critical: Current file size is 4096bytes

I'm able to use the plugin locally and it's giving me correct data
./check_myfilesize.pl /userdata/datastore/lib/config/datastore_007/msgs.db 10000000000 100000000000
OK: Current file size is 6219264bytes

Is anyone can help me on this to resolve this or any suggestions to use different plugin for this use case?

Thank You

Sorry guys.

We can close this issue as it is resolved. posted here after few days of facing the issue and gave it a one last try with some modifications in the command argument.

Solution is as below (posting here as I thought, It will be useful to others)

./testncpa.py -H HOSTNAME -t TOKEN -M plugins/check_myfilesize.pl -a '"/userdata/datastore/lib/config/datastore_007/msgs.db" 10000000000 10000000000'

or

./testncpa.py -H HOSTNAME -t TOKEN -M plugins/check_myfilesize.pl -a "'/userdata/datastore/lib/config/datastore_007/msgs.db' 10000000000 10000000000"


Using the Single quotes around the whole argument list, and a double quotes around the file path or vice versa, ensures that NCPA passes our file path as a single argument to the perl plugin I am using.
