Power Supply Issue

I am seeing an issue where as the Dell server has dual power supplies, we pull the power from one of the power supplies and the power supply graph shows the power supply down, but monitoring does not show 'down', it shows 'up' and no alerts are received. Monitoring shows 'true' like it is monitoring the PS.

 

When I model the server, it just removes the power supply out of the list.  When power is restored, it adds the power supply back, but no alerts are received.

 

I am using Dell Monitor 2.7 by Egor

 

Using Centos 5.7 x64

Zenoss 3.2.1

 

 

This is a critical issue because this is monitoring our datacenter overseas.

 

Thanks for all your help.

    Sorry, we've been quite busy at the ZCA, so this has fallen behind. So your issue is that the SNMP agent on the Dell isn't sending a clear trap? Or that you want to set up a perf check for if a PSU is available?

     

    If the latter, you might want to consider a command datasource, and see if there's a CLI method to access the PSU status on the Dell... Then look into SSH for running the command. . .

    It's simple to use eventclearclasses to set the CLEAR severity event from the PSU trap (may need to map that event to set the severity etc) so it clears the other event. I'm not sure if the DellMon pack is supposed to do that for PSUs or not. I'll Ping Egor.

    So what you really want to happen is the trap from the PSU going down should map to an event class with a severity of, say, error. Then the PSU up trap should map to the same event class with a severity of clear. Then clear all existing events, and test.
