pmdadbping - database response time and availability PMDA
Описание (Description)
pmdadbping is a database response time measurement PMDA.
pmdadbping runs dbprobe(1), and exports the performance
measurements it makes available as PCP metrics.
dbprobe(1) should be configured to use the type of DBI
appropriate for the local database, which includes: RDBMS
flavour, user/password, delay between "ping" requests, and the
SQL statement to use.
Установка (Installation)
Configure dbprobe(1) - it uses a configuration file from (in this
order):
• /etc/pcpdbi.conf
• $PCP_PMDAS_DIR/dbping/dbprobe.conf
This file can contain overridden values (Perl code) for the
settings listed at the start of dbprobe.pl, namely:
• database name (see DBI(3) for details)
• database user name
• database pass word
• SQL statement to measure (probe)
• delay between probes
Once this is setup, you can access the names and values for the
dbping performance metrics by doing the following as root:
# cd $PCP_PMDAS_DIR/dbping
# ./Install
To uninstall, the following must be done as root:
# cd $PCP_PMDAS_DIR/dbping
# ./Remove
pmdadbping 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).
