Create cronjob inside the Checkmk site

With crontab -l, you will get an overview of all installed crontabs inside the Checkmk site.

OMD[mysite]:~/etc/check_mk/multisite.d/wato$ crontab -l
#
# Do not edit this file. It will be recreated each time OMD
# is started or reloaded.
#
# execute 'omd reload crontab'
# to rebuild this file out of /omd/sites/mysite/etc/cron.d/*

Step-by-step guide

1. Option

   1. create a file below /omd/sites/mysite/etc/cron.d with your new cronjob, e.g. /omd/sites/mysite/etc/cron.d/myjob


      # My cronjob
      */5 * * * * $OMD_ROOT/local/myjob --params >/dev/null 2>&1

      


   2. execute 'omd reload crontab' to rebuild this file from/omd/sites/mysite/etc/cron.d/*
      
      
2. Option
   1. The second possibility is to create a systemwide cronjob below /etc/cron.d, e.g. /etc/cron.d/myjob. Note the slightly different syntax: the 6th column (after the time settings) requires the user under which this cronjob is executed. Also, the environment variables $OMD_ROOT and such are not available (unless you set them explicitly in this file):
