Nagios plugin to check a monitored cron


This repository provide a way to monitor the execution of a cron.


To monitor it, you have to run it with the provider launcher run_monitored_cron by prefixing the command executed by crond. Crontab example:


*/5 * * * * root /path/to/run_monitored_cron /path/to/monitored_cron [monitored cron args...]


This launcher will maintain three files named base on monitored cron basename:


    

  • a status file : Empty file updated on each successfully execution (Default: /run/[name].stat)
    • 

  • a PID file : Present only when the cron is running and contain the PID of the running process (Default: /run/[name].pid)
    • 

  • an errors file : Present only when error(s) occured in previous executions and contains details on this error(s) (Default: /run/[name].err)
    • 



You will able to monitor the execution of this script using the provide check_monitored_cron script:

    -h          Show this help message
    -D [path]       Specify the directory where run_monitored_cron store state files (default : /run)
    -w [minutes]        Specify WARNING time in minutes for status file (default : 30)
