Yes, VictoriaMetrics works well for this application.

Is data that is kept in the WAL considered "historical" in this context?
I was reading that the WAL drops data after ~2 hours. The way our system
works, hosts may be disconnected for a while during logging. Typically
it is only 30-60 minutes, but it can be longer. Is the 2 hour age limit

No, you definitely *cannot* use pushgateway for this.
Pushgateway is only for recording the *last* metric written. It cannot
record a history of measurements; neither can prometheus import historical
measurements (by scraping or any other means).

I wonder if you could use a Push Gateway to which all the spotty hosts
would write to. They could write locally the metrics to a file and keep
trying to push the metrics once they have the connectivity to the central
Prometheus.

Another option to look at for the remote write target is Victoria Metrics.
I like this because it's a trivial single-binary install. You can point
multiple prometheus instances at it with remote_write protocol (as well as
various other write protocols and formats), and you can query it directl
Yes, the only good option to retain data in remote nodes like this is to
have Prometheus running in the remote location. If it's one-off nodes,
you'll need a localhost Prometheus. The good news is, this is relatively
efficient, as the minimum footprint of Prometheus is pretty small.
As for how to
I have an application where I am trying to aggregate metrics from hosts
that have spotty connectivity. I want to be logging locally when the hosts
are periodically offline, then sync all the metrics to a central server
once they connect again. Another complication is that these remote hosts
