NAME

       pmdaresctrl - resctrl performance metrics domain agent (PMDA)

SYNOPSIS

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

DESCRIPTION

       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
       https://github.com/torvalds/linux/tree/master/Documentation/arch/x86/resctrl.rst.

INSTALLATION

       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.

PCP ENVIRONMENT

       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.
