Duplicate Alerts in Alertmanager UI

[jjneely]

I'm running Alertmanager 0.3.0 with Prometheus 1.2.1.

I've setup Alertmanager to route alerts to multiple different receivers. So a single alert routes to the responsible team, and to a webhook. Apparently, since there are two matching receivers the alert appears twice on the Alerts tab of the Alertmanager web UI.

I would expect that the alert would only be displayed once. I know it will be confusing to other members of our ops team.

Currently we show a semi-flattened version of our routing hierarchy. If an alert ends up in two different groups, being displayed twice is thus the expected behavior.

I understand how it's not ideal. To fix it, we have to come up with a different way to display alerts in general that makes sense.

@jjneely This will be fixed with the new UI (See branch ui-rewrite).

Closing here. Let me know if you have further questions.
