Monitoring Power on Dell Cluster using SNMP

dellelectrical-powersnmp

I have to monitor/collect Power Values of a dell cluster remotely using SNMP . I have very little experience regarding this. Could anybody guide me through , step by step on how to collect or maybe get a logfile of power values from the dell cluster at an interval of say 1 second ?

EDIT : OK, I learnt that , to get power values , we have to submit the appropriate set of OIDs with SNMP, to be able to access power values.

But any pointers on what the OID for accessing Power values in a cluster are ? I believe it is manufacture dependent ?

If you install the Dell Open Manage Server Administrator (Dell Linux OMSA Repo) it includes an SNMP agentX module that the net-snmp daemon and allow you to query all of the Dell specific vendor information. You can get all the MIBs from Dell which will enable you to translate the numeric OIDs to human-readable text that can assist you in easily identifying the ones you're looking for as well as what the values returned mean.

This information can then be monitored by any SNMP-enabled system like Cacti, Nagios, etc to provide trending, tracking and alert notifications.

Dell Poweredge power management

If you are concerned about the fan speed (and noise) consider this. On my Poweredge 2500, the only way I've found to control the fan speed is to adjust the temperature thresholds. If the maximum temperature is too close to the current reading, the fan spins faster trying to cool it off. When you raise the maximum temperature, the fan relaxes. So check to see if your thresholds are set too low.

Of course, if your thresholds aren't set too low, then you have a separate issue regarding cooling.
