6 pmdakvm - Linux virtualization performance metrics domain agent (PMDA)
7
9 pmdakvm is a Performance Metrics Domain Agent (PMDA) which exports met‐
10 ric values from the Linux KVM (Kernel Virtual Machine) virtualization
11 subsystem.
12
13 Per-processor KVM trace metrics from the kernel events enumerated below
14 /sys/kernel/debug/tracing/events/kvm can be configured statically using
15 the pmdakvm configuration file, /etc/pcp/kvm/kvm.conf.
16
18 Optionally configure trace points in the configuration file, then
19 install the KVM PMDA by using the Install script as root:
20
21 # cd $PCP_PMDAS_DIR/kvm
22 # ./Install
23
24 To uninstall, do the following as root:
25
26 # cd $PCP_PMDAS_DIR/kvm
27 # ./Remove
28
29 pmdakvm is launched by pmcd(1) and should never be executed directly.
30 The Install and Remove scripts notify pmcd(1) when the agent is
31 installed or removed.

47 Environment variables with the prefix PCP_ are used to parameterize the
48 file and directory names used by PCP. On each installation, the file
49 /etc/pcp.conf contains the local values for these variables. The
50 $PCP_CONF variable may be used to specify an alternative configuration
51 file, as described in pcp.conf(5).
