Munin not generating graphs - Make sure CRON job is running

I am currently using Ubuntu 12.04 on EC2.

If your munin master is not running, you should check if munin is set up as a CRON job.

List all the scheduled cron jobs:

crontab -l

If munin-cron is not set up, we will add it. Edit the crontab file

crontab -e

Let's make munin master run every 5 mins. Append the following to the end of the file

*/5 * * * * /usr/bin/munin-cron

Let's make munin run.

sudo -u munin munin-cron
