NAME

6       perfevent.conf  - the Performance Co-Pilot perfevent PMDA configuration
7       file

SYNOPSIS

10       $PCP_PMDAS_DIRS/perfevent/perfevent.conf
11

DESCRIPTION

13       The perfevent.conf configuration file defines  which  hardware  perfor‐
14       mance counters are enabled by the perfevent PMDA.
15
16       The configuration file contains a list of events that should be enabled
17       for each PMU. The perfevent PMDA detects which PMUs  present  and  pro‐
18       grams  the  configured events. If multiple PMUs are available, the per‐
19       fevent PMDA uses the order of the entries in the configuration file  to
20       determine which PMU settings to use. The entries at the top of the con‐
21       figuration file have higher precedence.   Only  one  PMU  configuration
22       setting is used.
23

FILE FORMAT

25       The  file consists of one or more groups of PMUs and the events that go
26       with them.
27
28       The PMU identification string is enclosed in brackets and one  or  more
29       events are listed below, one per line.
30
31              ["PMU identification string"]
32              EVENT_NAME [CPU OPTION]
33              ...
34
35       The available event cpu options are as follows:
36
37       cpu    to add the counter to all cpus in the system
38
39       cpu_rr to add to one of the cpus in a round-robin allocation strategy
40
41       node   to add the counter to the first cpu in each numa node
42
43       node_rr
44              to  add  the  counter  to the cpus in each numa node in a round-
45              robin allocation strategy
46
47       [N]    where N is the numerical digit of the CPU index
48
49       if the CPU option is absent then the event is programmed on all cpus.
50
51       Blank lines are ignored. Lines that begin with the # sign are ignored.
52
53       Multiple, comma separated, PMUs may be specified in the PMU definition.
