Having a repeat_interval less than group_interval should result in a notification being sent each group_interval. Setting the two to be equal to force this behavior seems to make sense in...

Do you have a metrics backend in mind that you are interested in supporting?

I would recommend following RED -- it's going to expose all of the metrics info that should be relevant to every webapp. Rate, Errors, and Duration, each partitioned by path/method/status...

From looking at the code, it doesn't appear like much data is actually ever repopulated by the method that ends up getting called -- either `from_json` or `from_hash`, depending on...

Are these double-notifications happening consistently? There's no concensus between alertmanagers -- if they receive the initial alert at different times from a prometheus server, the created alert groups in the...

Your logs are indicating some weird behavior: ``` level=info ts=2018-09-09T18:55:27.128662897Z caller=cluster.go:595 component=cluster msg="gossip not settled" polls=0 before=0 now=3 elapsed=2.000096829s level=info ts=2018-09-09T18:55:31.128969079Z caller=cluster.go:595 component=cluster msg="gossip not settled" polls=2 before=3 now=2 elapsed=6.000402722s...

The connection logs are only written during start-up, they aren't logged if the connection flaps. In the initial cluster connection code, a resolved IP address that equals the instance's IP...

`--log.level=debug` will output more logs

The primary form of gossip between the nodes is done over UDP, which might be getting lost between datacenters.
