Symstat command

Hi

I am collecting the performance data using symstat comand. I need to collect performance data for all the devices and ports for every five minutes(300 second). what command option i need to use so that i can get the performace data for symdevices and ports for every five minutes(300 second).

Can I use the below comand

Symdevices:( every three hundred seconds ,count 1 for all the devices in symmetrix box)

symstat -sid 6163 -i 300 -c 1  -v

Port:( every three hundred seconds ,count 1 for all the ports in symmetrix box)

symstat -i 300 -c 1 -type PORT -sid 0256 -dir ALL -port ALL

Can you please correct me if i am wrong.

Thanks

Naren

Re: Symstat command

You would be MUCH better off collecting STP data at 5 minute intervals which would give you those metrics and more.

Re: Symstat command

On any host with solutions enabler there is a STP daemon you can start.

You can start it with the command "stordaemon start storstpd"

You can show the options with the command "stordaemon show storstpd"

The CLI manuals should have details on the stordaemon storstpd options

You will need the performance mananger viewer from ECC or get the STP Navigator program from your EMC team.

Re: Symstat command

Hi Quincy

Thanks for your reply.

1. Is performance mananger viewer from ECC or  STP Navigator program is must to view data from stordaemon deamon.

2. Is there is any CLI which i can use to retrieve data from stordaemon directly without depending on performance manager viewer or STP navigator.

Thanks

Re: Symstat command

The output from the STP daemon is a zipped TTP file which is a text file.  It is possible to parse the TTP file, but I never do that since viewing the stats in STP navigator is so easy.

Re: Symstat command

Hi Quincy

We are planning to parse the TTP file because we doing some preprocessing to generate custom reports. Can you point out any documents about how to generate TTP file and how to generate specific TTP file( for example Port Performance, Symdev performance). Do you have any samples of TTP file. Can you please attach it if you have any.

Thanks

Re: Symstat command

STP daemon will create ttp files.

I have attached a zipped TTP file.

Hi Quincy

Thanks for the attachment. Can you please point out some documents how to generate and intrepret the data in the TTP files.

Thanks

Re: Symstat command

I've already attached a document that shows the commands to start, configure and stop the daemon.

I'm not sure of any documents on how to interpret the data.  Again Performance Manager/STP navigator is the easiest way, it can export to excel  How were you going to interpret the symstat commands?

What are you trying to accomplish?

If you do go the symstat method, I would recommend using an FA CPU that isn't being used heavily.  The syscall traffic from lots of symstat commands could cause performance issues.
