Re: evaperf tutorials

The link below is an excellent white paper on how EVAperf is used in analyzing EVA performance. How to use it and what to do with the data when you collect it.

Have fun.

Once it's in production it's all bugs after that.

Re: evaperf tutorials

I used the following instructions for capturing EVA-data:

EVAperf installation verification
â ¢ Open a DOS box and change directory to the evaperf directory. By default this is C:\Program Files\Hewlett-Packard\EVA Performance Monitor.
Dos> c:
Dos> cd \Program Files\Hewlett-Packard\EVA Performance Monitor
â ¢ Execute the following command from that directory:
Dos> evaperf ls
â ¢ Below you see an example of the output of the evaperf ls command.
Device Path Target LUN Product Product Ctlr Serial Harware Name Node
ID ID ID Rev. Ver.
---------- ---- ------ --- ------- ------- ---- -------------- ------- ------------------- -------------------
\\.\Scsi3: 0 4 0 HSV100 3025 V02T P66C5D4AAPV02T 100 5000-1FE1-5000-77A0 5000-1FE1-5000-77A0
\\.\Scsi3: 0 10 0 HSV100 3025 V00Q P66C5D4AAPV00Q 100 5000-1FE1-5000-77A0 5000-1FE1-5000-77A0
â ¢ Note that you see two controllers for each EVA. If you donâ t see them: troubleshoot.
Setting up the friendly names file
By default WW ids are used by EVAperf as you can see in the last picture of the previous section. You can create a friendly names list which will make performance investigation easier.
â ¢ Open a DOS box and go to the EVAperf folder which by default is located at:
C:\Program Files\Hewlett-Packard\EVA Performance Monitor
â ¢ Setup the Command View EVA host by typing in the command:
Dos> evaperf fnh administrator
Where the ip addrees is the address of the Command View EVA host.
â ¢ Create a new fnames.conf file with the following command:
Dos> evaperf fn
â ¢ Below you see an example of a friendly name file with one Vdisk, one host and one disk group.
Fnames.conf:
# Generated: Wed Aug 31 10:14:44 2005

# Arrays visible from host: 16.4.9.10
ARRAY 5000-1FE1-5000-77A0 CustomerServices

# Virtual disks for array: CustomerServices
VDISK 6005-08B4-0001-37AE-0000-9000-022A-0000 HP-UX\RX7600_npar1 disk1

# Hosts for array: CustomerServices
HOST 5006-0B00-0024-5A6E HP-UX\RX7600_npar1

# Disk groups for array: CustomerServices
DISKGROUP 5000-1FE1-5000-77A0:0 Disk Group
â ¢ Verify if the friendly names are used:
Dos> evaperf ls
Device Path Target LUN Product Product Ctlr Serial Harware Name Node
ID ID ID Rev. Ver.
---------- ---- ------ --- ------- ------- ---- -------------- ------- ---------------- -------------------
\\.\Scsi3: 0 4 0 HSV100 3025 V02T P66C5D4AAPV02T 100 CustomerServices 5000-1FE1-5000-77A0
\\.\Scsi3: 0 10 0 HSV100 3025 V00Q P66C5D4AAPV00Q 100 CustomerServices 5000-1FE1-5000-77A0
â ¢ Note that you see names below the Name header in stead of WW ids.

Capturing host port statistics
Use the following command to capture the host port statistics:
evaperf hps -csv cont n -dur n -sz array > meeting.txt
â ¢ -csv specifies comma separated output. This format is useful for importing large amounts of data into a spreadsheet for analysis.
â ¢ -cont n runs command continuously at interval specified by n. The default interval is one second.
â ¢ -dur n specifies the duration of a continuous mode session. For example, if you enter evaperf hps -cont 2 -dur 30, host port data is displayed at two second intervals for a total of 30 seconds.



Capturing virtual disk statistics
Use the following command to capture the virtual disk statistics:
evaperf vd -csv cont n -dur n -sz array > meeting.txt
The command parameters are described in the preceding section.
Virtual disk statistics are useful for identifying a virtual disk that has significant activity at a given point in time. For example, assume a storage system with multiple virtual disks that are all nearly idle with the exception of a single virtual disk. To perform an online upgrade, it may be desirable to halt the application that is imposing the load on the busy logical drive. This may be preferable to doing an offline upgrade.







Capturing all HP Command View EVAPerf statistics
If you would like to capture all the HP Command View EVAPerf statistics, use the following command:
evaperf all -csv -cont 6 -dur n -sz array > meeting.txt
