My /var/log/messages and /var/log/secure files are filling up fast:

It was recommended to:

"Check your xinetd configuration. Either /etc/xinetd.conf or /etc/xinetd.d/*.
Looks like you have logging switched on in there."

However, does not state on how to edit this.

There is a "log_facility=daemon" entry in the nrpe.cfg ,but I haven't found any documentation on that entry and if it has anything to do with "Disabling" NRPE from syslogging so much.

I'm not scertain whether NRPE properly supports log levels, but if it does, you can raise the level to log, by adding a line in /etc/xinetd.d/nrpe like:

Code: Select all

log_type        = SYSLOG daemon warning

where the last word is one of emerg, alert, crit, err, warning, notice, info, or debug. (The default is info.)

Thanks.

I just found the following, which I have not tried yet:

To disable the NRPE (or any other daemon that uses xinetd) logging to syslog:

go to /etc/xinetd.d
vi nrpe
remove the "log_on_failure...." and "log_on_success..." lines and save
restart xinetd

Removing the "log_on_failure...." and "log_on_success..." lines did not work.

I modified my xinetd.d file to look like the following:
# default: on
# description: NRPE (Nagios Remote Plugin Executor)
service nrpe
{
flags = REUSE
socket_type = stream
port = 5666
wait = no
user = nagios
group = nagios
server = /usr/local/nagios/bin/nrpe
server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd
log_on_failure += USERID
log_type = FILE /var/log/nrpe.log
disable = no
only_from = 127.0.0.1 remoteserver
}

I then added this file in /etc/logrotate.d
/var/log/nrpe.log {
missingok
notifempty
sharedscripts
}

Which makes the nrpe files rotate so I don't have to care about them. Just a tip.

I've asked the Linux Admins to adjust the files, as suggested below. Once they do, I'll post the feedback.

Thank you!

I haven't heard from the Linux Admins here at my company, so I will place a "Green Check mark" on this one until I hear from them.

Thank you for all your input!

You bet, thanks for the update!
