"pmrep proc" takes too long
Last modified: 2016-12-01 19:17:41 EST
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.
Fixed upstream by commits 0429f633e7 and ede27b6961.
