Performance Counter for dedup

Hi there,

I am looking for which performance counter to monitor for dedup process. I tried to lookup at PA but none matched.

Appreciate if anyone could share on this.

Thx

Performance Counter for dedup

Is there anything in specific you want to monitor? The basics I suppose are "sis status" that will give you the volumes asis is running on, whether it's enabled or not and the last time it was run.

If you're in diag mode ("priv set diag") you get many more counters to monitor. Included are lots of SIS counters:
