MSA1000 fails to update performance monitor.

Hi all

i have an old HP MSA1000 in production and lately there has been some complaint from the customer side about performance issues . from the storage side the only command that i can think of is show perf but when i type it in i get below results

CLI-1> show perf

start perf

show perf

stop perf

If you have a SAN switch in the MSA1000 (many come with a 2/8 Brocade SAN switch) - you could get details out of that too (port errors etc).

Thanks alot johan,

Just one more thing; i noticed that performance events are not logged in the event_log, if i do a "start perf" will they be logged? if so what are the thresholds and if not how can i do a long term performance monitoring on my system (lets say a week) without installing the HP-SIM or a similar monitoring tool?

(FYI: there is no SAN switch)

Hey, I have no hands-on knowledge about these commands so no idea about where they might be logged or not.

To monitor performance without tool perhaps you could make a script.
