I’ve had this weird issue happening for a while now, albeit only every now and then. Sometimes I only receive either a problem or recovery alert. So either I’d get a random recovery alert and think… ‘that was down?’ or I’ll wake up to a problem alert and think ‘WHAATT!?!’.
Every time this has happened the host has only been unresponsive for a few minutes (enough to trigger the alert), so I’m not sure if it is something to do with the quick change of state or something. We have the same issue with the install I use at work.
Both installs are using the official docker image/compose.
