EVAPerf – Set up

EVAPerf is the performance monitoring utility that I’d used extensively to troubleshoot the performance issues. There is a good documentation available on HP website but if you are in a rush, following information should be a quick guide.

EVA performance stats for an array is stored on CV server managing it. Also, evaperf daemon runs on all servers where CV is installed. You could designate a single CV server as your main evaperf server and collect the stats from all all CV servers.

Steps to set up evaperf in general are as below. The output is a CSV file which can be opened in excel to produce excellent graphs (pivot) using the data collected.

1. Authenticate all CV servers with evaperf server

This will prompt for the password and you should see the output same as below:
C:\Program Files\Hewlett-Packard\EVA Performance Monitor>evaperf fnh CVSERVER1 administrator
password:
Host Username Accessible
——– ————- ———-
CVSERVER1 administrator Yes
C:\Program Files\Hewlett-Packard\EVA Performance Monitor>evaperf fnh CVSERVER2 administrator
password:
Host Username Accessible
——– ————- ———-
CVSERVER2 administrator Yes

2. Create friendly names for all vdisks (by default it uses uuid of vdisk and when you have thousands it is not easy to track the ones you are interested in)
C:\Program Files\Hewlett-Packard\EVA Performance Monitor>evaperf fn

3. Start monitoring it. This could be done in a couple of ways:
C:\Program Files\Hewlett-Packard\EVA Performance Monitor>evaperf all -csv -ts2 -cont 20 -dur 1800 -sz 5000-1234-1234-1234 > test.csv

(this saves all parameters for each array in a single file-Collection at interval of 20 secs for duration of 1800 seconds will have the output test.csv of about 1.2MB; Collection at interval of 20 secs for 2 hours will have the output of about 43 MB)

OR

C:\Program Files\Hewlett-Packard\EVA Performance Monitor>evaperf all -csv -ts2 -cont 20 -dur 1800 -sz 5000-1234-1234-1234 -od test.csv

(this saves all parameters for each array in a single file)

OR

C:\Program Files\Hewlett-Packard\EVA Performance Monitor>evaperf mof -csv -ts2 -cont 20 -dur 1800 -od test.csv

(This saves individual parameters in different csv files for each EVA)

where
-cont 20 -> interval of 20 secs
-dur 1800 -> 30 mins

4. Convert test.csv output into TLVIz (TimeLine Visual) compatible format using evaperf-tlviz-format.exe tool. This should create several files whose name are in TLVIZ-***.CSV format.

5. Open these TLVIZ-***.CSV files using tvliz.exe to see the graphs.
