Kevin Klues commented on MESOS-5255:
------------------------------------
This will involve changes to the ResourceStatistics protobuf as well:
{noformat}
include/mesos/mesos.proto
include/mesos/v1/mesos.proto
{noformat}
It will also involve changes to the webui to report this information (in file):
{noformat}
src/webui/master/static/slave_executor.html
{noformat}
Look for the line below and mimic what is done for CPUs:
{noformat}
<td>GPUs</td>
<td class="text-right">
N/A
</td>
{noformat}
Also in:
{noformat}
src/webui/master/static/slave_framework.html
{noformat}
{noformat}
<tr>
<td>GPUs</td>
<td class="text-right">
N/A
</td>
<td class="text-right">{{framework.gpus | number}}</td>
</tr>
{noformat}
> Add support for GPU usage in metrics endpoint

> Currently the usage callback in the Nvidia GPU isolator is unimplemented:
> {noformat}
> src/slave/containerizer/mesos/isolators/cgroups/devices/gpus/nvidia.cpp
> {noformat}
> It should use functionality from NVML to gather the current GPU usage and add
> it to a ResourceStatistics object. It is still an open question as to exactly
> what information we want to expose here (power, memory consumption, current
> load, etc.). Whatever we decide on should be standard across different GPU
> types, different GPU vendors, etc.
