Response
|
|
--------
|
|
|
|
Starting from **microversion 2.48** diagnostics response is standardized
|
|
across all virt drivers. The response should be considered a debug interface
|
|
only and not relied upon by programmatic tools. All response fields are listed
|
|
below. If the virt driver is unable to provide a specific field then this field
|
|
will be reported as ``None`` in the response.

**Example Server diagnostics (2.48)**

.. warning::
|
|
Before **microversion 2.48** the response format for diagnostics was not
|
|
well defined. Each hypervisor had its own format.
|
|
|
|
**Example Server diagnostics (2.1)**
|
|
|
|
Below is an example of diagnostics for a libvirt based instance. The unit of the return
|
|
value is hypervisor specific, but in this case the unit of vnet1_rx* and
|
|
vnet1_tx* is octets.
