pmdakvm - Linux virtualization performance metrics domain agent (PMDA)
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.
$PCP_SYSCONF_DIR/kvm/kvm.conf configuration file for the pmdakvm agent $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
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).
