Re: [MirageOS-devel] CPU and memory utilisation

[Anil Madhavapeddy <anil@xxxxxxxxxx>]

Hi Masoud,

The CPU utilisation is most easily done from the outside by using "xentop"
or similar tools to gather the virtual machine utilisation.  The unikernel
will just be sitting blocked when there's no IO, so this is accurate.

Memory can be obtained via the OCaml GC module; Mindy's reply has a link
to the easy way to use it to generate HTML.

A more subtle question: are you trying to get this information from *within*
the unikernel to alter its behaviour in response to load?  In that case you'll
need a slightly more sophisticated way to measure CPU usage from within the
VM.
