Can't see any Performance metrics

[Noel_Torres]

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?

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?

[Dardan]

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.

[Noel_Torres]

3PAR cli% srstatpd -btsecs "2020-02-11 11:00:00"

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.
