pmdadbping - database response time and availability PMDA
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.
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.
$PCP_PMDAS_DIR/dbping/dbprobe.conf probe configuration file for dbprobe(1), used indirectly by pmdadbping $PCP_PMDAS_DIR/dbping/Install installation script for the pmdadbping agent $PCP_PMDAS_DIR/dbping/Remove undo installation script for the pmdadbping agent $PCP_LOG_DIR/pmcd/dbping.log default log file for error messages from pmdadbping
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).
