Features missing in the webui
When adding features we try to ensure the webui is updated accordingly.
However, there have been a few gaps where the webui has not been updated to
reflect the addition of functionality.
I filed the following epic to collect gaps in functionality:
https://issues.apache.org/jira/browse/MESOS-6440
For example, one that came to mind after discussing with Zhitao is that we
don't display the volumes present on the agent. If you know of any features
that have been added that are missing webui updates please file a ticket
under this epic so that we can collect them together and try to catch the
webui up to the latest state of things.
If there are any ongoing projects that warrant webui updates, don't forget
to make webui changes as part of completing the project.
Any thoughts or feedback?
Ben

Thank you for checking. I also read through the source quickly and
couldn't figure out if the whitelist status was exposed. Makes sense to
expose this information as part of the API but changing the alive field
could break backwards compatibility. Would it be worthwhile to create a
new issue for this or is there an existing issue that this could be
added to?

@Konrad I checked and it looks like Mesos master doesn't expose whitelist
in API so it can't be presented in WebUI. I think this information +
maintenance information should be included in state endpoint for each
slave. Currently there is only alive field maybe it should be extended to
something like state and have information like alive, maintenance, down,
unknown.

I am referring to the --whitelist flag[1] for the mesos master:
<quote>
Path to a file which contains a list of agents (one per line) to
advertise offers for. The file is watched, and periodically re-read to
refresh the agent whitelist. By default there is no whitelist / all
machines are accepted. Path could be of the form file:///path/to/file or
/path/to/file.
</quote>
If a node is not listed in the whitelist file, it is effectively in
maintenance/draining mode but it still shows up in the webui agent list
as an active agent without any indication that the offers from this
agent are not being sent to schedulers. Have you have changed the agent
summary page or list to display maintenance information? If so that may
be a good place to add information about whitelist status. Something
simple like "State: Draining" would be helpful.
Thanks

Hi Konrad
Currently I'm working on displaying table with maintenance schedule.
I'm sorry I don't understand what whitelist you referred to. Do you want to
display some additional information on offers screen? Could you provide an
example?

I am currently using Consul and Consul-template (with mesos 0.27.2) to
dynamically generate an agent whitelist on each mesos master. I have
often wished that the webui would indicate if a node's offers were being
dropped because it isn't in the whitelist. Do the maintenance mode webui
patches take into account whether a node is whitelisted?
Thanks

At MesosCon EU we were working on bringing Maintenance Mode to the UI.
Maintenance of nodes will be presented in a table. Code is on github but
need some tweaks and tests with large maintenance json. I'll prepare patch
shortly (when github DDoS will be over).
