pmdasendmail: sendmail performance metrics domain agent (PMDA)
NAMEpmdasendmail - sendmail performance metrics domain agent (PMDA)
SYNOPSIS$PCP_PMDAS_DIR/sendmail/pmdasendmail [-d domain] [-l logfile] [-U username]
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 sendmail(1) and hence the sendmail PMDA.
A brief description of the pmdasendmail command line options follows:
- 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.
- 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.
- 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.
INSTALLATIONIf 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
