pmdahaproxy - HAProxy PMDA
pmdahaproxy is a Performance Metrics Domain Agent (PMDA) which
extracts live performance data from HAProxy statistic socket.
See the HAProxy documentation for detailed description of each
metric.
pmdahaproxy reads an optional ini-style configuration file
· $PCP_PMDAS_DIR/haproxy/haproxy.conf
This file can contain in its [pmda] section overriding values for the
following PMDA options:
· user
· socket
By default, root and /var/lib/haproxy/stats, are used as values for
these options, respectively.
Note that the HAProxy statistics socket needs to be separately
enabled in the HAProxy configuration file; please refer to the
HAProxy configuration documentation for details. Depending on system
and HAProxy configuration, using non-root user may also be possible.
Once the needed setup is ready, you can test the connection and
install the PMDA to enable access to the names and values for the
HAProxy performance metrics. To install, do the following as root:
# cd $PCP_PMDAS_DIR/haproxy
# ./connect
# ./Install
To uninstall, do the following as root:
# cd $PCP_PMDAS_DIR/haproxy
# ./Remove
pmdahaproxy 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).
