I'm after some software to measure the power draw of a HP Server, namely a DL360 series. I know Nagios is used for logging and monitering but I'm not sure if it logs power usage as well. I've also tried to find the HP Server Management package but am not sure if this shows power usage either. I'm thinking my best bet would to buy some sort of device that goes inbetween the wall and the servers plug.

Can anybody suggest what would do for me?

You can try a clamp-on meter, but the HP Management Software works as well :)

You can download the appropriate HP software for your server model/generation/OS from here.

Are you on Windows or Linux? What generation is your DL360? If you don't want to dig into the GUI of the HP Management Agents on Linux, the hpasmcli utility will show the power supply reading on demand in Watts. Depending on the version of the utility/server, you may see individual power supply readings or the system's power meter reading:

Power Meter #1
        Power Reading  : 274


Power supply #1
        Present  : Yes
        Redundant: Yes
        Condition: Ok
        Hotplug  : Supported
        Power    : 35 Watts
Power supply #2
        Present  : Yes
        Redundant: Yes
        Condition: Ok
        Hotplug  : Supported
        Power    : 275 Watts

I'm on a G5 Series running Windows. Thanks for the link, I could only find the specs for the current series (G7/8). I'll give the software a go tomorrow then will probably mark as the answer. – tombull89 Dec 22 '10 at 22:44
If you have the bandwidth, be sure to download and install the entire "Proliant Support Pack". That will provide all of the management agents and monitoring for the server. – ewwhite Dec 22 '10 at 22:47
Wasn't quite expecting how much different downloads would be avalible...I've gone for the System Management Homepage and will set up the (3-part?!) support pack for download shortly. – tombull89 Dec 22 '10 at 23:00
You should only need the Proliant Support Pack. – ewwhite Dec 22 '10 at 23:07
hokaydoke, thanks. – tombull89 Dec 22 '10 at 23:22
