CMU 7.1 - Actions and Alerts Issue
Hi Again:
Trying to gather statistcs in the new gui. On BL2x220 G6s, no problem everything works great. However, on my BL2x220 G5s, I can't see any statistics whatsoever. I tried using the native commands and the collectl commands. No data whatsoever.
Is there a way I can troubleshoot this?

Re: CMU 7.1 - Actions and Alerts Issue
Hello,
Please check following things;
- Is passwordless ssh enabled from head node to problematic nodes?
- Is CMU monitoring agent (cmu_cn-7.1-1.x86_64.rpm) is installed on those nodes?
- Do you have firewall running between head node and problematic compute node?
- Are monitoing agents running on problematic nodes?
Please run this command on head node;
# /opt/cmu/bin/pdsh -w <nodelist> ps -ef | grep Monitoring | /opt/cmu/bin/dshbak -c
<nodelist> should be hostname of nodes having problem. eg: n[1-5]
- Look in these logs to debug issue;
Head node:
/opt/cmu/log/MainMonitoringDaemon_<head node name>.log
Node on which secondary monitoring daemon is ruuning (above command will show this):
/opt/cmu/log/SecondaryServerMonitoring_<compute node name>.log
Problematic compute nodes:
/opt/cmu/log/SmallMonitoringDaemon_n1.log
If it doesn't solve problem, please post above things here and send us logs.

Will get back to you with regard to the following instructions:

Sorry for the delay. However, now that all of the other issues have been resolved, I will be able to concentrate on my final problem with 7.1. Thank you for all of these suggestions.
