If you want to want to know if it's running you can do something like sudo status cron or ps aux | grep cron.

If you want to know if your cron jobs are running, check /var/log/syslog with the process name cron. For example:

Apr 26 21:17:01 example CRON[18055]: (root) CMD (   cd / && run-parts --report /etc/cron.hourly)

It all depends on how syslog is configured. Some distributions/Unix will split everything out, other dump just about everything into one file. –  David Apr 30 '10 at 17:09

By default the cron log in ubuntu is located at /var/log/syslog. Use the below command to check the cron entries in this file.

grep cron /var/log/syslog

  1. modify rsyslog config: open /etc/rsyslog.d/50-default.conf,remove # before cron.*
  2. restart rsyslog service: sudo service rsyslog restart
  3. restart cron service: service cron restart

now you can check cron log from file /var/log/cron.log
