PMDADBPING(1) General Commands Manual PMDADBPING(1)
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).
dbprobe(1) pmcd(1), PCPIntro(1) and DBI(3).
