+.SH NAME
+\f3pmdapapi\f1 \- \*(ia performance metrics domain agent (PMDA)
+.SH SYNOPSIS
+\f3$PCP_PMDAS_DIR/pmda\*(ia\f1
+[\f3\-d\f1 \f2domain\f1]
+[\f3\-l\f1 \f2logfile\f1]
+.SH DESCRIPTION
+.B pmda\*(ia
+is a \*(ia Performance Metrics Domain Agent (PMDA) which exposes
+hardware performance counters via the library Performance API (Papi).
+.PP
+The metrics exported by the \*(ia PMDA report values gathered from
+the hardware counters and metrics available, as reported by \*(ia.
+Currently, only root users may access such metrics.
+.PP
+A brief description of the
+.B pmda\*(ia
+command line options follows:
+.TP 5
+.B \-d
+It is absolutely crucial that the performance metrics
+.I domain
+number specified here is unique and consistent.
+That is,
+.I domain
+should be different for every PMDA on the one host, and the same
+.I domain
+number should be used for the same PMDA on all hosts.
+.TP
+.B \-l
+Location of the log file. By default, a log file named
+.I \*(ia.log
+is written in the current directory of
+.BR pmcd (1)
+when
+.B pmda\*(ia
+is started, i.e.
+.BR $PCP_LOG_DIR/pmcd .
+If the log file cannot
+be created or is not writable, output is written to the standard error instead.
+.SH INSTALLATION
+If you want access to the names, help text and values for the \*(ia
+performance metrics, do the following as root:
+.PP
+.ft CW
+.nf
+.in +0.5i
+# cd $PCP_PMDAS_DIR/\*(ia
+# ./Install
+.in
+.fi
+.ft 1
+.PP
+If you want to undo the installation (and remove both PMDAs),
+do the following as root:
+.PP
+.ft CW
+.nf
+.in +0.5i
+# cd $PCP_PMDAS_DIR/\*(ia
+# ./Remove
+.in
+.fi
+.ft 1
+.PP
+.B pmda\*(ia
+is launched by
+.BR pmcd (1)
+and should never be executed directly.
+The Install and Remove scripts notify
+.BR pmcd (1)
+when the agent is installed or removed.

+.SH "PCP ENVIRONMENT"
+Environment variables with the prefix
+.B PCP_
+are used to parameterize the file and directory names
+used by PCP.
+On each installation, the file
+.B /etc/pcp.conf
+contains the local values for these variables.
+The
+.B $PCP_CONF
+variable may be used to specify an alternative
+configuration file,
+as described in
+.BR pcp.conf (5).
