Check PSU Status

Hello,

We have a cluster and each server have 2 PSU.
An alarm should be raised in case of failure so we need to check periodically the PSU status wth a script.

The first idea was to check with ipmitool but this take some time to get the data and we face some other issues now due to that delay.
Using ipmitool we can parse the watt consumption for both supplies of each server and in case is 0 mean the PSU fails.

I was wondering if i can do the same with dmidecode which is executed faster.
I tried the following two commands but the problem is that i see only one PSU information.

Code:

#  dmidecode -t 39
# dmidecode 2.11
SMBIOS 2.7 present.

crm_verify

CRM_VERIFY(8)							  [FIXME: manual]						     CRM_VERIFY(8)

NAME

       crm_verify - check the CIB for consistency

SYNOPSIS

	   crm_verify [-V] -x file

	   crm_verify [-V] -X string

	   crm_verify [-V] -L|-p

	   crm_verify [-?]

DESCRIPTION

       crm_verify checks the configuration database (CIB) for consistency and other problems. It can be used to check a file containing the
       configuration or can it can connect to a running cluster. It reports two classes of problems, errors and warnings. Errors must be fixed
       before Heartbeat can work properly. However, it is left up to the administrator to decide if the warnings should also be fixed.

       crm_verify assists in creating new or modified configurations. You can take a local copy of a CIB in the running cluster, edit it, validate
       it using crm_verify, then put the new configuration into effect using cibadmin.

OPTIONS

       --help, -h
	   Print a help message.

       --verbose, -V
	   Turn on debug information.

	       Note
	       Increase the level of verbosity by providing additional instances.

       --live-check, -L
	   Connect to the running cluster and check the CIB.

       --crm_xml string, -X string
	   Check the configuration in the supplied string. Pass complete CIBs only.

       --xml-file file, -x file
	   Check the configuration in the named file.

       --xml-pipe, -p
	   Use the configuration piped in via stdin. Pass complete CIBs only.

EXAMPLES

       Check the consistency of the configuration in the running cluster and produce verbose output:

	       crm_verify -VL

       Check the consistency of the configuration in a given file and produce verbose output:

	       crm_verify -Vx file1

       Pipe a configuration into crm_verify and produce verbose output:

	       cat file1.xml | crm_verify -Vp

FILES

       /var/lib/heartbeat/crm/cib.xml--the CIB (minus status section) on disk. Editing this file directly is strongly discouraged.
