Open Stack

Events shouldnt help much since the workflow is, user does something. It breaks with "error notify admin" then admin needs to figure out why... ideally there needs to be a field for why in the db, and the dashboard can show it to admins?

Thanks,
Kevin

Maybe cinder can emit more notification events, then a dashboard can be build separately with the appropriate access control and filtering? The same dash can then be used for many projects - all they need to add are the events with enough metadata

Hi,

When we create a volume in the horizon, there may occurrs some errors at the driver
backend, and the in horizon we just see a “error” in the volume status.

So is there any way to put the error information to the horizon so users can know what happened exactly just from the horizon?
Thanks,
Liu

​The challenge here is that the calls to the driver are async, so we don't actually have any direct feedback/messages regarding the result.  One thing that's been talked about in the past is adding additional information to the status which could be presented so that end users and tools like Horizon would have a little more information.

The trick is however we also do NOT want driver info going back to the end user, the whole point of Cinder is to abstract all of that backend specific type stuff.  The idea kicked around in the past was to introduce a sub-state with a bit more detail, but still wouldn't be anything specific from the driver.

Sounds like a good topic to revisit for the Liberty release.​


Agreed that driver messages shouldn't reach the end user, but would it be helpful at all to the administrator to have driver error messages visible on the admin panel?
