How long has a remote probe been storing the collected data while the core server was down?

If the corever is restored, does it send all the data during that period to the core server?

Thanks in advance.

Hey Jonathan,

please see a summary from our manual page:

If the connections between the PRTG core server and a probe fail for any reason (for 
example, restarting the PRTG core server system), the probe continues to monitor and 
stores the results. During a connection loss, a buffer stores a maximum of 500,000 
sensor results in the RAM of the remote probe system (up to 50 - 200 MB). This means 
that for 100 sensors with a 1-minute scanning interval, the monitoring results of up to 
3 days can be buffered (or 52 minutes for 10,000 sensors with a 1-minute scanning 
interval). The probe automatically reconnects to the PRTG core server as soon as it 
is available again and transmits all monitoring results gathered during the connection
 loss.

Best regards,
