NAME
pmdadbping - database response time and availability PMDA
DESCRIPTION
Simple database response time measurement PMDA. dbprobe.pl(1) should
be configured to use the type of DBI appropriate for your database,
which includes: RDBMS flavour, user/password, delay between "ping"
requests, and the SQL statement to use. pmdadbping runs dbprobe.pl(1),
and exports the performance measurements it makes available as PCP
metrics.
INSTALLATION
Configure dbprobe.pl(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
If you want to undo the installation, do the following 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.
