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.
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, 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.
