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.
