Hello All,
I am using Nagios Core 4.4.6 and I have a problem with nrpe logging .

So nrpe is logging too much messages in syslog.(on servers that I monitor) Are there possibilities to limit messages like shown below.

I've checked the log options at /etc/nagios/nrpe.cfg and the only solution I could find was to stop all logging.

# This option allows you to enable or disable logging error messages to the syslog facilities.
# If this option is not set, the error messages will be logged.
disable_syslog=1

NRPE v 4.0.0

There's a parameter for logging to an nrpe.log or whatever you name it. Maybe try disabling syslog and defining the nrpe log. If it grows a lot don't forget a logrotate for it...
