I have to get power measurements of a dell cluster (Linux OS) running a specific workload , with an interval of 1 second (retrieveing power values every second) . I can either use Windows or Linux as a local machine to gather/collect the data. The questions I have are
Is it possible to retrieve values every second ? Does the cluster return power values at that rate ?
If Dell OpenManage has to be installed on the cluster to return the power values to me, how can I know if it is installed ?
Can I do it without Dell Open Manage being installed on the cluster ?
I have installed Cacti on my local machine running fedora (with yum install cacti) . Now how do I open the tool ? (sorry for being so naive , I'm new to this and have no guidance from anyone)
I think I figured out the OID for getting power values from dell snmp manual . What command should I be using to retrieve the power measuerements now ?
I'd be very thankful to anyone who resolves my questions as this is very important for me.
