Need help on understanding object performance counters

[ Edited ]

Hi All,


Can anybody briefly explain about the object performance counters in filer, I was implemented the historical graphs for Volume performance parameters like avg_latency, read_latency, write_latency etc...  for avg_latency it giving some values like 59227669621 and for read_latency 54389813570. Is this values are cumulative values?

I need to take the difference value from current value to previous value, this diff value is the correct latency value? If this diff value is something like 6347525, is it the correct value of latency?


Can any one briefly expalin about the counter values?


Thanks in Advance!!
