- What is the shortest data interval that PRTG reports on?
- In what intervals does PRTG retain data?
- How long does PRTG retain 1 minute data in 1 minute interval before rolling that data into its next interval? For example if 1 minute is the shortest data interval monitored, does 1 minute data get rolled into 5 minute data after 1 hour?
- Can you change the length of time that an interval is retained? For example if 1 minute data is kept 60 minutes before rolling up to 5 minutes, can that 1 minute data retention be changed to 120 minutes?
- Where do I find the documentation for these answers?
