NAME
       pmdaapache - Apache2 web server performance metrics domain agent (PMDA)

SYNOPSIS
       $PCP_PMDAS_DIR/apache/pmdaapache  [-d  domain]  [-l logfile] [-U username] [-S server] [-P
       port] [-L location]

DESCRIPTION
       pmdaapache is a Performance Metrics Domain Agent (PMDA) which extracts performance metrics
       describing the state of an Apache web server.

       The  apache  PMDA exports metrics that measure the request rate, cumulative request sizes,
       uptime and various connection states for active clients.

       This information is obtained by performing a HTTP request to the server status URL,  which
       must be enabled in the httpd.conf configuration file.

	    ExtendedStatus on
	    <Location /server-status>
	    SetHandler server-status
	    Order deny,allow
	    Deny from all
	    Allow from localhost
	    </Location>

       A brief description of the pmdaapache command line options follows:

       -d   It is absolutely crucial that the performance metrics domain number specified here is
	    unique and consistent.  That is, domain should be different for every PMDA on the one
	    host, and the same domain number should be used for the same PMDA on all hosts.

       -l   Location  of the log file.	By default, a log file named apache.log is written in the
	    current directory of pmcd(1) when pmdaapache is started,  i.e.   $PCP_LOG_DIR/pmcd	.
	    If	the log file cannot be created or is not writable, output is written to the stan-
	    dard error instead.

       -S   Query the Apache status information from the named server rather than the local host.

       -P   Query the Apache status information from the given port rather than the default (80).

       -L   Specify an alternative location for finding the server-status page.

       -U   User account under which to run the agent.	The default  is  the  unprivileged  "pcp"
	    account  in  current  versions  of	PCP,  but in older versions the superuser account
	    ("root") was used by default.

INSTALLATION
       If you want access to the names, help text and values for the apache performance  metrics,
       do the following as root:

	    # cd $PCP_PMDAS_DIR/apache
	    # ./Install

       If you want to undo the installation, do the following as root:

	    # cd $PCP_PMDAS_DIR/apache
	    # ./Remove

       pmdaapache  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

		 command line options used to launch pmdaapache
       $PCP_PMDAS_DIR/apache/help
		 default help text file for the apache metrics
       $PCP_PMDAS_DIR/apache/Install
		 installation script for the pmdaapache agent
       $PCP_PMDAS_DIR/apache/Remove
		 undo installation script for the pmdaapache agent
       $PCP_LOG_DIR/pmcd/apache.log
		 default log file for error messages and other information from pmdaapache

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 config-
       uration file, as described in pcp.conf(5).
