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 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).
