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).
