Can't see any Performance metrics

Hello all:

I can't see any Performance metrics in two of my 3PAR systems, neither on web interface nor on HP 3PAR Management Console.

In Management Console, Performance & Reports graphs show all empty since a date in december.

In web interface, no data appears since the same date, so if you request "1 month" or less for a Volume, "No data to display" appears.

May something be misconfigured?

Re: Can't see any Performance metrics

There's an internal vvol called srdata which collects and keeps all perf and statistics.

You can check the status of this vvol by issuing: showvv .srdata

To view the status of system reporter, type: showsr
-> Confirm if you have any stats / numbers here.

Additionally, you could stop or start the System Reporter by issuing: stopsr and startsr

Hi Dardan:

Service Reporter is started. I can see this:

Seems that I should clean or enlarge .srdata , isnt't it? Which option is preferred?

Re: Can't see any Performance metrics

The .srdata volume is a protected fully provisionet vvol. I'm not sure if you can alter it with a customer userID. Have you tried to stop (stopsr) and start (startsr)?

The following CLI command will give you a historical performance report of the physical disks, the data is collected from the system reporter volume:

srstatpd -btsecs "2020-02-11 11:00:00"

If you can see these statistics, then your system reporter should be fine.

Finally I decided to perform a

controlsr grow -pct 100

but I would be grateful if there were a way to expire older records instead of consuming extra space.

See the HPE 3PAR Command Line Interface Reference for command details:

controlsr setretention [options] <category> <target>[-<max>]
