Would it be possible for us to run the script as admin/root user instead of nagios user.

Hi,
It is NOT recommended that you use "root" for this.
However, inside the "ncpa.cfg" file (on your NCPA remote agent) which defined user and group to run plugins.
Code: Select all
[listener]
#
# User and group to run plugins as (recommended to use nagios:nagios)
# Default: uid = nagios
# Default: gid = nagios
#
# ** Note - The daemon runs as root, but forks a child process when running a plugin
# that is defined by the user, for security reasons. However, without the main daemon
# running as root, much of the system information would be missing. This is typical behavior. **
#
# This is for Unix only (Linux, Mac OS X, etc)
#
uid = nagios
gid = nagios
What is the "log_file" path that your file is using?

log_file = /var/log
Permissions are :
ls -l kern.log
-rw-r----- 1 syslog adm 1185 May 13 22:29 kern.log

Hi,
Hope you are having a good day!!
Please change permission for "log_file":
Now try again:
Code: Select all
/usr/local/nagios/libexec/check_ncpa.py -H 10.0.60.35 -t 'cFvgpWMXjaZojGlk' -P 5693 -M 'plugins/nfs-error.py'

Hi,
Hope you are having a good day!!
Your python script looks fine.
However, if your "log_file" is large, checking each line for a matching string might not be a good solution especially if your log_file does not rotate each night.
So keep an eye on that log_file, don't let it get too big ...
May I close this thread?
