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

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;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.

FILES         top

           configuration file for the pmdahaproxy agent

           connection test helper using the pmdahaproxy agent configuration

           installation script for the pmdahaproxy agent

           undo installation script for the pmdahaproxy agent

           default log file for messages from the pmdahaproxy agent


       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).
