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.

              ["PMU identification string"]
              EVENT_NAME [CPU OPTION]
              ...

       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.
