Description Frank Ch. Eigler 2016-09-19 18:16:29 UTC

Marko reports "pmrep proc" takes on the order of many seconds.  Diagnosis with the aid of a systemtap script (ltrace and $PCP_DEBUG not being helpful) indicated that the pmrep is using the extend_item rather than extend_indom API for the metrics beneath proc.*, one instance per call.

This means that each extend_item involves another bunch of lookups, repeated over processes (the indom), and over metrics (proc.*).

pmrep should routinely use the extend_indom API for metrics with indoms.  (It can use the same API for metrics with a null indom!).  It can find the instance domain in the output results coming from each fetch.
