Delete old data



Hello friends,

How can I delete PRTG older data history? I'm already change the "History sensor data" to 30 days. But the space won't increase.

Do I have to delete data manually?

Thank you!

You can use the "Historic Data Purging" settings you find in PRTG under: "Setup -> System Administration -> Core & Probes" If you scroll down, you see the purging configuration. Any value is the number of days for which PRTG keeps the data before deleting it.
Also you can delete old data manually.Bear in mind these entries will no longer be available for graphs, tables, or reports.
To do so:
1) Stop the PRTG service
2) Backup your PRTG data folder!
3) Delete old data files
4) Start PRTG service

Also this article may be of interest for you: How and where does PRTG store its data?
