PMDADBPING(1)						       Performance Co-Pilot						     PMDADBPING(1)

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):

       o   /etc/pcpdbi.conf

       o   $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:

       o   database name (see DBI(3) for details)

       o   database user name

       o   database pass word

       o   SQL statement to measure (probe)

       o   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.

NAME

       pmdarpm - RPM packages performance metrics domain agent (PMDA)

SYNOPSIS

       $PCP_PMDAS_DIR/rpm/pmdarpm [-C] [-d domain] [-l logfile] [-r path] [-U username]

DESCRIPTION

       pmdarpm	is  a  Performance Metrics Domain Agent (PMDA) which extracts performance metrics reflecting the state of the RPM package database
       managed by rpm(1).

       The rpm PMDA exports metrics that describe each package installed on a system, as well as some cumulative totals.  When	the  RPM  database
       changes the PMDA automatically detects this and uses a background thread to asynchronously refresh its values.

       A brief description of the pmdarpm command line options follows:

       -C   Verify the package iteration code by scanning the RPM database once, then exiting.	Only useful for problem diagnosis and testing.

       -d   It	is  absolutely crucial that the performance metrics domain number specified here is unique and consistent.  That is, domain should
	    be different for every PMDA on the one host, and the same domain number should be used for the same PMDA on all hosts.

       -l   Location of the log file.  By default, a log file named rpm.log is written in  the	current  directory  of	pmcd(1)  when  pmdarpm	is
	    started,  i.e.   $PCP_LOG_DIR/pmcd.   If  the  log	file cannot be created or is not writable, output is written to the standard error
	    instead.

       -r   Specify an alternate path to the RPM database (default is /var/lib/rpm/Packages).

       -U   User account under which to run the agent.	The default is the unprivileged "pcp" account.

INSTALLATION

       If you want access to the names, help text and values for the rpm performance metrics, do the following as root:

	    # cd $PCP_PMDAS_DIR/rpm
	    # ./Install

       If you want to undo the installation, do the following as root:

	    # cd $PCP_PMDAS_DIR/rpm
	    # ./Remove

       pmdarpm 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 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	configura-
       tion file, as described in pcp.conf(5).
