pmdaapache

PMDAAPACHE(1)						      General Commands Manual						     PMDAAPACHE(1)

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 standard 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

       $PCP_PMCDCONF_PATH
		 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 configura-
       tion file, as described in pcp.conf(5).

SEE ALSO

       PCPIntro(1), httpd(8), pmcd(1), pcp.conf(5) and pcp.env(5).
