Unable to fetch graph for IO Service Time in munin

Question

I am implementing munin on my ec2 ubuntu 10.04 instance I was not able to fetch graph for IO stats but I figured out the problem and IO stats are working fine. But still I am not able to fetch the graphs for IO service Time, which is one of the very important parameter. Kindly help me.

Thanks

This could occur because of several reasons. Basic steps to debugging plugins are listed on the munin documentation :

• restart munin-node
• try to run the plugin via munin-run
• try to call the plugin via munin-node
• observe the munin log files
