We plan on using prometheus to fetch data from multiples servers and
the link between the metrics's server and the prometheus servers is

Most of the time prometheus will be able to fetch the metrics.
However, when prometheus is unable to pull the data the metrics server
will need to be able to cache them until the connection is back.
Since most of the time the connection will be up, I was thinking about
setting up a watchdog refreshed by the metric pull. When the watchdog
trigs, then cache the data until the pushgateway is pulled.
If anyone had any advise on that, that'd be appreciated.
Is it possible to run the Prometheus server on the other end of the link?
In general it is advised to run Prometheus servers as close as possible
to the things being monitored. For example a server per datacenter
instead of a single global server, etc.
