pmdasendmail - sendmail performance metrics domain agent (PMDA)
$PCP_PMDAS_DIR/sendmail/pmdasendmail [-d domain] [-l logfile] [-U
username]
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.
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
default help text file for the sendmail metrics
$PCP_PMDAS_DIR/sendmail/Install
installation script for the pmdasendmail agent
$PCP_PMDAS_DIR/sendmail/Remove
undo installation script for the pmdasendmail agent
$PCP_LOG_DIR/pmcd/sendmail.log
default log file for error messages and other information
from pmdasendmail
/etc/sendmail.cf
sendmail configuration file to identify the name of the
statistics file
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).
