Netflow Graphs time possibly incorrect

Votes:

0

Hello

Slightly odd question, i've created some netflow sensors to recieve data from our PFsense routers, the sensors work fine, except the timestamps for the data is 1 hour behind, i.e the graphs show the live data, but chart's x axis for time is 1 hour behind, we are on GMT time, all our other sensor graphs show the correct time, the timezone are our PRTG server and on our routers are all the same

Is there something i'm not fundimentally understanding with netflow, is the data supposed to arrive 1 hour late? is this to do with active flow timeout setting? it's currently set at 60 minutes, does this mean it send netflow data with a 1 hour delay, as opposed to seeing the data in real time?

Hello,

Thank you for your KB-post.

Exactly, this is related to active flow timeout settings. For more information, please have a look at the following article: https://kb.paessler.com/en/topic/66485-what-is-the-active-flow-timeout-in-flow-sensors
