PMDAKVM(1)

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).
