pmdakvm is a Performance Metrics Domain Agent (PMDA) which exports metric values from the Linux KVM (Kernel Virtual Machine) virtualization subsystem.
Per-processor KVM trace metrics from the kernel events enumerated below /sys/kernel/debug/tracing/events/kvm can be configured statically using the pmdakvm configuration file, /etc/pcp/kvm/kvm.conf.
Optionally configure trace points in the configuration file, then 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.

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).
