NAME

       pmdakvm - Linux virtualisation 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

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

	       # cd $PCP_PMDAS_DIR/kvm
	       # ./Install

       If you want to undo the installation, 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
