I had configured the option 'Historic Sensor Data' set to 9999 on Historic Data Purging.
Are all monitoring raw data actually stored for 9999 days by this setting?
Can I actually print 9999 days of data as a Historic Data Report with 'No Interval'?
What is the maximum value for storing raw data?

Hello Jonathan,
This setting will purge the data after 500 days. PRTG will store the raw data in the Monitoring Database for this time span.
You can run a report for the entire time span as Historic Data Report. However this can take very long.
Kind regards
