Nagios XI Cron Jobs

[dhatha03]

I understand that Nagios XI needs to run a set of Cron jobs on a regular basis and that they are critical to the operation of Nagios. It appears that the majority of them are set to run every minute. These jobs running every minute are filling my audit log up pretty quickly, close to 30,000 records for a 24-hour period. Are there recommendations on different time intervals for these jobs, then the defaults? Listed below is the current (default) configuration:

# /etc/cron.d/nagiosxi: crontab fragment for nagiosxi

# Backup MySQL & PostgreSQL Databases
0 7 * * * root /root/scripts/automysqlbackup
0 7 * * * root /root/scripts/autopostgresqlbackup > /dev/null 2>&1

* * * * * nagios /usr/bin/php -q /usr/local/nagiosxi/cron/sysstat.php >> /usr/local/nagiosxi/var/sysstat.log 2>&1

Thank you.

these are recommended to stay just how they are. As a matter of fact changing them will have adverse affects and cause Nagios XI to not run properly.

Thank you for the information, I will leave them as is.
