NAME         top

       pmdahaproxy - HAProxy PMDA

DESCRIPTION         top

       pmdahaproxy is a Performance Metrics Domain Agent (PMDA) which
       extracts live performance data from HAProxy statistics socket or
       URL.

       By default the HAProxy stats socket is used to retrieve the
       metric but if the optional URL option is set (see below), then
       the HAProxy URL is used instead.

       See the HAProxy documentation for detailed description of each
       metric.

INSTALLATION         top

       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.

       The section can also contain the following parameters:

           • url
           • auth
           • pass

       When the url option is defined, URL connection to HAProxy is
       used.  pmdahaproxy expects CSV data from the HAProxy URL; an
       example of a compatible URL is http://127.0.0.1:9000/?stats;csv .

       Note that the HAProxy statistics socket and/or URL need 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, especially with URL based connections.

       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.

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).
