Hi,

Start alertmanager by

alertmanager --config.file=./alertmanager.yml --storage.path=./data --data.retention=1h`, But after 1 hour the expired silenced still showd in web UI, so how to delete the expired soon?

I did a lot tests and generated many invalid expired silences and make the web UI so slow. I want to delete the expired silences soon.

Looking forward to your reply.Thanks a lot!

BTW, I use go run main.go --config.file=./alertmanager.yml --storage.path=./data --data.retention=1h in test env, and open localhost:9093 to test when the expired silences disappear, but didn't achieve my expected effect.

Expired silences are deleted every 15 minutes. Try checking the
alertmanager_silences_gc_duration_seconds_count metric.
