pmdabpf is a Performance Co-Pilot (PCP) Performance Metrics
Domain Agent (PMDA) which extracts live performance data from
eBPF programs utilizing BPF CO-RE (libbpf and BTF).
pmdabpf loads and acts as a bridge for any number of configured,
separate bpf PMDA modules. Existing libbpf tools should be
possible to be utilized with the bpf PMDA modules with reasonable
See the eBPF, libbpf and BPF CO-RE documentation for detailed
pmdabpf reads a mandatory ini-style configuration file:
Each section of the file corresponds to one bpf PMDA module. The
following global options are available for every module (their
default values are shown in parenthesis):
A boolean value to specify whether this bpf PMDA module
should be started or not.
Modules may also support additional module-specific configuration
options, refer to the default configuration file for their
To install, the following must be done as root:
# cd $PCP_PMDAS_DIR/bpf# ./Install
To uninstall, the following must be done as root:
# cd $PCP_PMDAS_DIR/bpf# ./Removepmdabpf is launched by pmcd(1) and should never be executed
directly. The Install and Remove scripts notify pmcd(1) when the
agent is installed or removed.
Some modules will start providing values only after having
collected data from related system activity.

Note that the usual/default value for $PCP_PMDAS_DIR is
/var/lib/pcp/pmdas and the default for $PCP_LOG_DIR is
/var/log/pcp but these settings are platform dependent.
Environment variables with the prefix PCP_ are used to
parameterize the file and directory names used by PCP. On each
installation, the file /etc/pcp.conf contains the local values
for these variables. The $PCP_CONF variable may be used to
specify an alternative configuration file, as described in
