I've been using remote probes almost a year and I just realized that it doesn't seem like they are buffering data when they lose the connection.
The article at this htttp:www.paessler.com/manuals/prtg8/remote_probes_and_multiple_probes.htm states the following:
"During a connection loss a buffer stores a maximum of 500,000 sensor results in RAM memory of the remote probe system (up to 50 - 200 MB). This means that for 100 sensors with one minute interval the monitoring results of up to 3 days can be buffered (or 52 minutes for 10,000 sensors with one minute interval)."
If that were really the case then I would very rarely have gaps in my monitoring data. My remote probes typically have fewer than 100 sensors and don't have anything scanning faster than 5 minute intervals and yet if I look at the graphs and tables I can see plenty of short gaps in coverage of just a few minutes or hours. It appears that no buffering is done at all.
Unfortunately I don't see a way to attach pictures but I'd be glad to attach examples of what I'm talking about. The typical case would be that I see a gap in the green displayed on the Probe Health sensor and if I look at various sensors in the probe during that time, they don't have any data.
