symcli command to check FA percentage utilisation
Experts,
Using symstat I can retrieve various performance statistics regarding disks/pools/ports etc. However, I am interested in finding out percentage utilisation of FA ports and symstat have no option for the same. I know I can do this using Performance Analyser but I want to know a command which I can use in a script to produce graphs in crontab.
Please share the command if there's any.
Cheers
Ketan

For your workload, you can work with your account team to figure out what your FA utilization is at a given IO rate. Once you know that, you can figure out what IO rate will correlate to a given utilization rate.
There are 4 IO types a FA CPU can perform, and all of them have different maximum rates. Also IO size can make a big difference.

hi k2pattua,
symstat command does not provide the FA CPU utilization. Using command "symstat -sid xxx -type port -dir 11e -port 0 -i xx -c xx" give you some basic statistics about the port you specified. You may review the symmextrix documentation depending on your model to compare the values with the ranges in where the array should be working. Otherwise, like you said. using SPA to have the data.

BTW, your question written to the users' own "Discussions" space don't get the same amount of attention and questions can go unanswered for a long time, You can select "Move" under ACTIONS along the upper-right. Then search for and select: "Symmetrix Support Forum" which would be the most relevant for this question.

Thanks for your reply. Will have to go down the path of calculating the % util based on values.
This was my first question and hence didn't realise it was being created within my dicussion space. Now moved into Symmetrix Support Forum.

Do you have EMC Control Center installed? If not, as Quincy56 said, your best option in to contact your EMC account team and tell them about your issue. There are *.ttp files that are stored periodically in the Symmetrix Service Processor and those files gather statistics of all Symmetrix components, including FA ports and directors. If you have Control Center, those files will be *.btp and will contain the same info.

Thanks for replies. I am aware of most of the avenues mentioned so far. Graph for % Utilisation can be plotted in Analyser, which means the values I am after are definitely there. Question is - is there a command to retrieve that value by any way - from ttp or btp or storstpd daemon directly or something else.
cheers

I had the same question once, and after trying hard with symstat and other ways, I was not able to get FA statistical info, so I had to use TTP instead...

Ketan,
You can use the "pmcli" command to export stats from ttp/btp files into csv format, which can then be parsed by a script. pmcli.exe should be in the Performance Manager directory.
Thanks,
