Имя (Name)

pmdakvm - Linux virtualization performance metrics domain agent
       (PMDA)

---

Описание (Description)

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.

---

Установка (Installation)

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.

---

Предостережение (Caveat)

When pmdakvm is running, it holds references to kernel resources
       within the KVM device driver.  It is thus not possible to unload
       or reload the device driver module while the PMDA is running.
       The ideal procedure to follow in order to reload the kernel
       module is the reverse of that described in the ``INSTALLATION''
       section above - i.e. first run ./Remove, then reload the kernel
       module, then run ./Install.

Окружение PCP (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).
