MRAID12G Performance Monitoring

[SamCU]

Hello,

Is there a way to gather the real-time statistics off this controller and fed them to Grafana on UCS Rack servers ( standalone or UCSM controlled )

Don't know if UCSM provides a way to gather the stats via SDK ?

Looking for solutions/methods out there for monitoring the controller I/O performance,

Thanks

[SamCU]

Anyone?

Don't know of any out-of-band storage performance details provided by CIMC/UCSM.

As far as I know the OOB data is all inventory/PID/configuration/etc which wouldn't include performance details.

Would be better off getting these details inband from the OS installed.

The MRAID is a LSI controller so any LSI monitoring software should work.

Thanks. The LSI software is probably an option as I read online that there is a flag to enable the stats with a performance penalty. However there is no documented procedure or details other than that. 

I will contact Broadcom support.

Thanks

Probably need to use storcli 

from https://docs.broadcom.com/doc/MR-TM-StorCLI-UG

storcli / cx show dpm
This command shows the drive performance monitoring status on the controller.
Input example:
storcli /c0 show dpm
storcli / cx start dpm
This command starts the performance monitoring on the controller.
Input example:
storcli /c0 start dpm
storcli / cx stop dpm
This command stops the performance monitoring on the controller.
Input example:
storcli /c0 stop dpm
storcli /cx delete dpmstat type = HIST | LCT | RA | EXT | All
This command deletes the drive performance monitoring statistics of the controller.
Where:
• HIST – Historgram of response time.
• LCT – Long Time commands.
• RA – Running average drive statistics.
• EXT – Extended DPM information.
storcli /cx[/ex]/sx show dpmstat type = HIST | LCT | RA | EXT [logfile[=filename]]
This command shows the drive performance monitoring statistics of the mentioned drive.

• HIST – Historgram of response time.
• LCT – Long Time commands.
• RA – Running average drive statistics.
• EXT – Extended DPM information.
• logfile – If the file name is not specified, it logs tostarsas.log or to a user-specified file.

Have always been told this should only be used for baselining, and troubleshooting, and to NOT just leave it running.

So I tried the "storcli" comand with dpm options but I get message which says "DPM feature is not supported"

This  MRAID12G is installed on C240 M5Sx box.

Ok it looks like DPM is compatible with 3Ware LSI controllers.

For MRAID12, I see the controllers supports "Performance Metrics = yes".  So I guess I've to install and check MSM software and figure out how to collect the performance stats. 

[SamCU]

Ok. The controller doesn't provides the performance stats by itself.  One has to use IOMeter or other similar tools.
