---------------------------------
Summary: Visualize resource usage per role in the UI
Key: MESOS-4414
URL: https://issues.apache.org/jira/browse/MESOS-4414
Project: Mesos
Issue Type: Improvement
Components: webui
Reporter: Ian Babrou
When running Mesos in multi-tenant environment with several roles and
frameworks, it's easy to be tricked that you have enough slack capacity. This
leads to unexpected delays in scheduling, since you are low on resources on
specific roles and unused chunks of resources are too small.
While this is also a monitoring issue, I think Mesos UI can do a better job of
vusualizing what resources are available for roles. I made a CLI tool to do
that for myself: https://github.com/bobrik/scrappy
In addition, it could be worth showing top available resource chunks per
resource:
* Biggest CPU intensive task that can be scheduled (with mem and disk)
* Biggest mem intensive task that can be scheduled (with cpu and disk)
* etc
These things can be monitored and alerted on, but it probably isn't the best
solution. Maybe it's a job for a separate service.
