Описание (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.

Установка (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.

Окружение PCP (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).
