[Observium] Sudden Burst's in Traffic

Dear ALL,

I am at version 0.16.11.8249 professional, this was working fine until recently, it is showing IPv4 traffic in GB's for some devices occasionally. Whilst other days it behaves normally.

Please note this is Mikrotik router which we are monitoring.

Please find attached graph.

Any clue apart from updating to latest version which i will do latter after testing, is highly appreciated.

Thanks, Afzaal
