How to monitor server dual power?

dears, any one knows how to use linux command to monitor hp server Redhat dual power status? any 1 of power failure then alarm will triggered.

What kind of HP server? For DL* and ML*, install the ProLiant Support Pack and use the hpasmcli to check the PSUs. You'll have to parse the output and send an email if there's a problem.

hi pludi thanks a lot. i am using DL380 G5/6/ i have download one support pack for RH5. would you mind to provide method to setup and to monitor?

Uncompress the PSP somewhere, and install the hp-health*.rpm and hp-snmp-agents*.rpm packages. The first one will install the hpasmcli utility which enables you to query any sensors and BIOS settings available. See hpasmcli -s 'help' for more details.

The second package will install an SNMP agent that enables you to query the server using any SNMP-enabled monitoring software. I've never used it, so I can't give you any more information on its configuration.
