NAME¶

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

SYNOPSIS¶

$PCP_PMDAS_DIRS/perfevent/perfevent.conf

DESCRIPTION¶

The perfevent.conf configuration file defines which hardware performance counters are enabled by the perfevent PMDA.

The configuration file contains a list of events that should be enabled for each PMU. The perfevent PMDA detects which PMUs present and programs the configured events. If multiple PMUs are available, the perfevent PMDA uses the order of the entries in the configuration file to determine which PMU settings to use. The entries at the top of the configuration file have higher precedence. Only one PMU configuration setting is used.

FILE FORMAT¶

The file consists of one or more groups of PMUs and the events that go with them.

The PMU identification string is enclosed in brackets and one or more events are listed below, one per line.

The available event cpu options are as follows:

cpu

to add the counter to all cpus in the system

cpu_rr

to add to one of the cpus in a round-robin allocation strategy

node

to add the counter to the first cpu in each numa node

node_rr

to add the counter to the cpus in each numa node in a round-robin allocation strategy

[N]

where N is the numerical digit of the CPU index

if the CPU option is absent then the event is programmed on all cpus.

Blank lines are ignored. Lines that begin with the # sign are ignored.

Multiple, comma separated, PMUs may be specified in the PMU definition.
