pmdasendmail

PMDASENDMAIL(1) 					      General Commands Manual						   PMDASENDMAIL(1)

NAME

       pmdasendmail - sendmail performance metrics domain agent (PMDA)

SYNOPSIS

       $PCP_PMDAS_DIR/sendmail/pmdasendmail [-d domain] [-l logfile] [-U username]

DESCRIPTION

       pmdasendmail is a sendmail Performance Metrics Domain Agent (PMDA) which exports mail traffic statistics as collected by sendmail(1).

       Before  the  sendmail PMDA can export any metrics, sendmail(1) must have statistics collection enabled.	This involves checking the name of
       the statistics file, as given by the OS or O StatusFile control lines in /etc/sendmail.cf, and then creating  this  file  if  it  does  not
       already exist.  Removing the file will terminate statistics collection by sendmail(1) and hence the sendmail PMDA.

       A brief description of the pmdasendmail 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 sendmail.log is written in the current directory of pmcd(1) when  pmdasendmail
	    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.

       -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.

       There are no communication options, as the Install script ensures the sendmail PMDA will be connected to PMCD by a pipe.

INSTALLATION

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

	    # cd $PCP_PMDAS_DIR/sendmail
	    # ./Install

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

	    # cd $PCP_PMDAS_DIR/sendmail
	    # ./Remove

       pmdasendmail 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_PMCDCONF_PATH
		 command line options used to launch pmdasendmail
       $PCP_PMDAS_DIR/sendmail/help

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).
