I only see 4 hosts at a time, and they are random.

I am unsure if I am doing something wrong, but there are a few hosts that I am monitoring, but for some reason they will not all show at the same time, and its random, but a few just come in and out, but I never see 4. here are some examples taken within a minuite of each other.

I have a similar problem. I also cannot see certain hosts, namely those that have either the value “Docker” or the value “Docker Host” under Settings/Agents in Type. All others, which are always visible, have the value “Host Docker.” For the affected hosts, the type also changes every few seconds between “Docker,” “Docker Host,” and “Host Docker.” Whenever “Host” comes first, I can also see the host under the Hosts tab. Can you check this for me?

I only get 4 hosts, no matter what.. here is a better image.. not sure if this was what you were asking for?

This appears to be related to a known issue where the unified agent's host type badge flickers due to timing issues in websocket state updates. A fix was committed (53a2c2a) that tracks previously-seen host types and preserves them during transient state inconsistencies.

This fix is on the main branch but hasn't been released yet. It should be included in the next release.

@morskipas - your observation about the Type changing between "Docker", "Docker Host", and "Host Docker" confirms this is the same root cause.

In the meantime, this is cosmetic only - the actual data collection is still happening. The host disappearing from the Hosts tab briefly is the UI losing track of the host type, not the host actually going offline.
