NAME

       pmdalmsensors - Linux hardware monitoring performance metrics domain agent (PMDA)

SYNOPSIS

       $PCP_PMDAS_DIR/lmsensors/pmdalmsensors [-d domain] [-l logfile] [-U username]

DESCRIPTION

       pmdalmsensors  is  a  Performance Metrics Domain Agent (PMDA) which extracts performance metrics describing the state of hardware using the
       lm-sensors on compatible motherboards.

       The lmsensors PMDA exports metrics that measure fan speeds, core temperatures and voltage levels.

       A brief description of the pmdalmsensors command line options follows:

       -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 lmsensors.log is written in the current directory of pmcd(1) when pmdalmsen-
	    sors 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.

       -U   User  account  under  which  to run the agent.  The default is the unprivileged "pcp" account in current versions of PCP, but in older
	    versions the superuser account ("root") was used by default.

INSTALLATION

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

	    # cd $PCP_PMDAS_DIR/lmsensors
	    # ./Install

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

	    # cd $PCP_PMDAS_DIR/lmsensors
	    # ./Remove

       pmdalmsensors 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).

NAME

       pmdaxfs - XFS filesystem performance metrics domain agent (PMDA)

SYNOPSIS

       $PCP_PMDAS_DIR/xfs/pmdaxfs [-d domain] [-l logfile]

DESCRIPTION

       pmdaxfs is a Performance Metrics Domain Agent (PMDA) which extracts performance metrics describing the state of the XFS filesystem from the
       Linux kernel.

       The xfs PMDA exports metrics that measure information about metadata  buffer  usage,  the  journal,  btree  operations,	inode  operations,
       extended attributes, directories, quotas, read and write operation counts and of course throughput.

       The PMDA provides a facility to reset the values of all counters to zero using pmstore(1) with the xfs.control.reset metric.

       A brief description of the pmdaxfs command line options follows:

       -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 xfs.log is written in  the	current  directory  of	pmcd(1)  when  pmdaxfs	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.

INSTALLATION

       The xfs PMDA is installed and available by default on Linux.  If you want to undo the installation, do the following as root:

	    # cd $PCP_PMDAS_DIR/xfs
	    # ./Remove

       If you want to establish access to the names, help text and values for the XFS performance metrics once more, after removal, do the follow-
       ing as root:

	    # cd $PCP_PMDAS_DIR/xfs
	    # ./Install

       pmdaxfs	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).
