NAME

       pmdahaproxy - HAProxy PMDA

DESCRIPTION

       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

       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.

FILES

       $PCP_PMDAS_DIR/haproxy/haproxy.conf

       $PCP_PMDAS_DIR/haproxy/connect
              connection test helper using the pmdahaproxy agent configuration

       $PCP_PMDAS_DIR/haproxy/Install
              installation script for the pmdahaproxy agent

       $PCP_PMDAS_DIR/haproxy/Remove
              undo installation script for the pmdahaproxy agent

       $PCP_LOG_DIR/pmcd/haproxy.log
              default log file for messages from the pmdahaproxy agent

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).
