How long is data stored in PRTG Hosted Monitor?



I can’t find any settings in PRTG Hosted Monitor about data storage and data deletion. What kind of data is stored? How long is it stored for?

Data retention and historic data purging

PRTG stores everything from monitoring configurations, data, and logs to tickets and reports in the PRTG data directory on the probe system. Data is also found in the PRTG program directory. These directories are not accessible for users of Paessler PRTG Hosted Monitor. Stored data is retained according to historic data purging limits. These limits cannot be changed by users of Paessler PRTG Hosted Monitor.

SettingDefault Purge Limits (Days)
Log File Records30
PRTG Web Server Log Records30
Historic Sensor Data365
Toplist Records30
Closed Tickets365
Configuration Auto-Backups30
Screenshots of HTTP Full Web Page Sensor10

Once these limits are reached, the system purges historic data, completely deleting them from the directories. Deleting unnecessary data helps free up disk space, which encourages improved system performance.
