Ping sensor data collection during core server outage




we have a core server and an exclusive remote probe to perform monitoring of (ping) sensors only for public data link and some SNMP of the internal network.

I realized that even shutting down the core server for a few minutes, I did not miss collecting information.

I know that the remote probe collects the information and sends the data to the core server database.

But I want to know how long I can stay with my core server off to perform maintenance without losing information.

Do I need a lot of disk space on the remote probe to store data during the time of maintaining the core server?

Thank you.

Hi Sandro,

During a Core - Probe 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).
