How long does PRTG save Netflow and can I adjust it?

Modified on 2025-06-10 22:34:01 +0200

Hello, About 4 month ago I enable Netflow on our virtual infrastructure. I am now looking at enabling Netflow v9 on our core network stack. In trying to estimate the effect on our PRTG server resources, I need to know how long does PRTG (by default) keep Netflow data? Also, is this setting adjustable?

Thanks

Jeremy

Hi Jeremy,

Received raw Flowdata information will be discarded as soon as it has been analyzed for the sensor's Toplists, which happens with every scanning interval configured for the sensor. Toplist data itself is stored by default for 30 days, which can be configured in Setup | System Administration | Core & Probes | Historic Data Purging.

Kind regards.
