Agent Buffering

Whenever there is maintenance on a central Checkmk site, metrics from the agents are not collected and after the maintenance
there are gaps in the graphs because the data is missing from during the maintenance time.
If the agents would be able to buffer metrics for a few hours, Checkmk would be able to catch up these metrics
and the gaps in the data could be filled. This Buffer does not need to take days but would be nice to survive at least some
downtime for upgrades / updates a few hours should be ok. Whilst we know the Agent is designed for real-time monitoring this
would be of really added value, since it is usually very interesting to have this data after an outage !
