pmdakvm: Linux virtualization performance metrics domain agent (PMDA)

NAME

pmdakvm - Linux virtualization performance metrics domain agent (PMDA)

DESCRIPTION

pmdakvm is a Performance Metrics Domain Agent (PMDA) which exports metric values from the Linux KVM virtualisation subsystem.

Unlike many PMDAs it dynamically enumerates its metric hierarchy, based entirely on the contents of /sys/kernel/debug/kvm.

INSTALLATION

Install the kvm PMDA by using the Install script as root:


cd $PCP_PMDAS_DIR/kvm

./Install

To uninstall, do the following as root:


cd $PCP_PMDAS_DIR/kvm

./Remove

pmdakvm 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.

FILES

$PCP_PMDAS_DIR/kvm/Install
installation script for the pmdakvm agent
$PCP_PMDAS_DIR/kvm/Remove
undo installation script for the pmdakvm agent
$PCP_LOG_DIR/pmcd/kvm.log
default log file for error messages from pmdakvm

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 configuration file, as described in pcp.conf(5).
