PMDASENDMAIL(1)PMDASENDMAIL(1)NAMEpmdasendmail - sendmail performance metrics domain agent (PMDA)
SYNOPSIS
$PCP_PMDAS_DIR/sendmail/pmdasendmail [-d domain] [-l logfile] [-U user‐
name]
DESCRIPTIONpmdasendmail 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 send‐
mail(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 num‐
ber 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 send‐
mail.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).
