Will Probe services continue to monitor while Core Server service is down?



Will the Probe services continue to monitor sensors while the Core Server service is stopped? Are some sensors affected but not others?

If the connections between core and probe fails for any reason (for example, a reboot of the computer running the core server) the probe continues its monitoring and stores the results. 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). The probe automatically reconnects to the core as soon as it is available again and transmits all monitoring results gathered during the connection loss.
