Monitoring HPE RAID controller battery via WMI

jaybone over 5 years ago

I've found a few things, mostly really old, on this subject.

As far as I can tell, monitoring an HP server via WMI doesn't show the RAID controller battery status at all, just the disks. From old stuff I found, it would seem that monitoring via SNMP is the only supported way to do that.

My questions are: is that still accurate, and if so, why?

I can use WMI to query my HPE servers' RAID battery status, no problem. What I haven't found so far is documentation from HPE as to what the result actually means. E.g.

gwmi -computername SomeServerName -class hpsa_arraycontroller -namespace root\hpq | fl elementname,batterystatus,pscomputername

elementname : Smart Array P420i Controller in Slot 0

batterystatus : 1

PSComputerName : SomeServerName

It *appears* that the batterystatus value returned by that query corresponds to the actual status of the battery:

empty = no battery installed

1 = OK

2 = dead

? = ? (I have no other statuses to check against)

Is there some way to get Solarwinds to return this kind of info when the node is being polled by WMI?

The only way I know to accomplish this is with the SAM WMI monitor, you'll have to build it custom. NPM doesn't have this capability.

I read on another forum that this info should also be available over SNMP once you’ve installed AMS / SNMP and the Controller Driver.
the linked documents are
HPE Support document - HPE Support Center
Drivers & Software - HPE Support Center.

Hope this helps

These are Hyper-V servers, so we need to use WMI for monitoring that, unfortunately.

To my knowledge you should be able to set up SNMP also on Hyper-V machines. Or are you using VMAN as well?
however once SNMP is set up you could use a SAM SNMP Monitor to grab the needed information.

SNMP doesn't get us the Hyper-V info.
I'm currently just adding the iLO interfaces to monitoring, and querying those with SNMP. I supposed I could also put a second IP address on the hosts and query those with SNMP, but the iLOs are already configured.
Either way, or even deverts's suggestion to use a custom SAM monitor seems kinda kludgey at best, or just a cash-grab to sell more licenses at worst. HP providing this level of detail via WMI is nothing new - seems like it should be baked into the existing WMI hardware monitors.

Do you have any pointers on configuring this in SAM please?
