I have been receiving the following msg in PRTG (using v220.127.116.111) : The netflow sensor has received and dropped flows with a timestamp older than the timespan defined by the active flow timeout.
I recently have added netflow to all our routers (40). Since then i have been getting the above message. But not often, once or twice a day, sometimes nothing. So im figuring this is a problem with only one of the devices. I wonder why the message cant specify which netflow sensor is causing this problem, cause searching on all routers is not really that great. I however have checked every router and all settings. After that i checked all the settings within PRTG. Everything is exacly the same on all devices, yet i still receive this error now and again.
Is there any way to track this ? what sensor is sending me this message ?
