NAME         top

       pmdabpftrace - bpftrace PMDA

DESCRIPTION         top

       pmdabpftrace is a Performance Co-Pilot (PCP) Performance Metrics
       Domain Agent (PMDA) which exports metrics from bpftrace(8) scripts.

CONFIGURATION         top

       pmdabpftrace reads an optional ini-style configuration file:

              $PCP_PMDAS_DIR/bpftrace/bpftrace.conf

       This file may contain [authentication] and [bpftrace] sections.
       Please refer to https://pcp.io/docs/lab.auth.html on how to setup
       authentication which is highly recommended as otherwise anyone could
       run any bpftrace(8) script as root.

       [authentication] section specifies values for the following settings
       (their default values are shown in parenthesis):

       enabled (True) A boolean value to specify whether authention is
                      required or not.  Please see the note above on
                      authention setup.

       allowed_users (root)
                      A comma-separated list of usernames which are allowed
                      to register bpftrace(8) scripts.

       [bpftrace] section specifies values for the following settings (their
       default values are shown in parenthesis):

       bpftrace_path (bpftrace)
                      Path to the bpftrace(8) executable.

       script_expiry_time (60)
                      Unnamed scripts are removed after this period of time
                      (in seconds) in case there has been no requests for
                      their values.

INSTALLATION         top

       To install, the following must be done as root:

           # cd $PCP_PMDAS_DIR/bpftrace
           # ./Install

       To uninstall, the following must be done as root:

           # cd $PCP_PMDAS_DIR/bpftrace
           # ./Remove

       pmdabpftrace 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.

FILES         top

       $PCP_PMDAS_DIR/bpftrace/bpftrace.conf
            configuration file for the pmdabpftrace agent

       $PCP_PMDAS_DIR/bpftrace/Install
            installation script for the pmdabpftrace agent

       $PCP_PMDAS_DIR/bpftrace/Remove
            undo installation script for the pmdabpftrace agent

       $PCP_LOG_DIR/pmcd/bpftrace.log
            default log file for messages from the pmdabpftrace agent

       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.

PCP ENVIRONMENT         top

       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 pcp.conf(5).
