NAME         top

       pmdaresctrl - resctrl performance metrics domain agent (PMDA)

SYNOPSIS         top

       $PCP_PMDAS_DIR/pmdaresctrl [-d domain] [-l logfile]

DESCRIPTION         top

       pmdaresctrl is a resctrl Performance Metrics Domain Agent (PMDA)
       which exposes performance metrics values from the /sys/fs/resctrl
       interface to provide information on the last level cache.

       Further details on linux support for last level cache metrics can
       be found at .

INSTALLATION         top

       If you want access to the names, help text and values for the
       resctrl performance metrics, do the following as root:

            # cd $PCP_PMDAS_DIR/resctrl
            # ./Install

       If you want to undo the installation (and remove both PMDAs), do
       the following as root:

            # cd $PCP_PMDAS_DIR/resctrl
            # ./Remove

       pmdaresctrl 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.

       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).  In particular, the $PCP_RESCTRL_DIR may be set to
       change the default directory from /sys/fs/resctrl.
