<!--
|
|
|
|
Configuration file for virtual host metrics daemon (vhostmd).
|
|
|
|
A better, less noisy, more minimal configuration file
|
|
which doesn't depend on Xen.
|
|
|
|
Supported metric types are: int32, uint32, int64, uint64, real32,
|
|
real64, and string.
|
|
|
|
A metric's value is set to the output produced by executing its action.
|
|
|
|
'action' can include the special token NAME, in which case the name of
|
|
the vm currently under inspection is substituted for NAME. Only useful
|
|
within the vm element.
