pmdakvm — Linux virtualization performance metrics domain agent (PMDA)


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.


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.

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).
