Power or Energy preferred? Do you mind getting the DC value rather than AC value (the DC values are a bit more fine grained, AC values are only at the chassis level (obviously). AC v. DC just represent PSU inefficiencies. inefficiencies.
We have been doing most of our telemetry improvement confluent side, e.g.: [jjohnson2@leonidas ~]$ nodesensors smm2 ac_power smm2: AC Power: 207 W [jjohnson2@leonidas ~]$ nodesensors smm2 ac_power -c node,AC Power (W) smm2,207 [jjohnson2@leonidas ~]$ nodesensors smm2 ac_power -c -i 2 -n 3 time,node,AC Power (W) 2019-12-20T19:32:50.712,smm2,208 2019-12-20T19:32:52.724,smm2,208 2019-12-20T19:32:54.738,smm2,208 ]$ nodesensors d1-d8 dc_energy d1: DC Energy: 1.37273 kWh d2: DC Energy: 1.74668 kWh d3: DC Energy: 12.23641 kWh d4: DC Energy: 17.70769 kWh d5: DC Energy: 18.92555 kWh d6: DC Energy: 7.31230 kWh d7: DC Energy: 1.22393 kWh d8: DC Energy: 1.69922 kWh [jjohnson2@leonidas ~]$ nodesensors d1-d8 sys_power d1: Sys Power: 10.00000 W d2: Sys Power: 20.00000 W d3: Sys Power: 50.00000 W d4: Sys Power: 20.00000 W d5: Sys Power: 50.00000 W d6: Sys Power: 30.00000 W d7: Sys Power: 10.00000 W d8: Sys Power: 10.00000 W [jjohnson2@leonidas ~]$ nodesensors d1-d8 sys_power |stats -t 10.0|=========================================================================== 14.0| 18.0|=================== 22.0| 26.0| 30.0|=================== 34.0| 38.0| 42.0| 46.0|====================================== Samples: 8 Min: 10.0 Median: 15.0 Mean: 23.75 Max: 50.0 StandardDeviation: 16.5359456942 Sum: 190.0 From: Damir Krstic <[email protected]> Sent: Friday, December 20, 2019 11:50 AM To: xCAT Users Mailing list <[email protected]> Subject: [External] [xcat-user] programmatically getting power telemetry from nextscale and SD530 Is there a programmatic way of getting the power usage telemetry out of NextScale FPCs and SD530 chassis? I know that we can access that info using the web interface by signing in to the FPC and viewing the power information. However, I would like to do this across the entire cluster in order to record the cluster's power usage. If I had to guess ipmitool may be able to do it, but I am unsure what, or how to get that information using ipmitool. Thank you. Damir
