Question

Hi Guys,

We have the Teltonika Rut240 router with a 4G sim on 50 sites. We have noticed there's been a massive spike in Data usage which we can't explain. Is there a way to determine what is causing this usage? We have remote access through the RMS, we have noticed the same issue on different firmware versions. One site in April sent and received almost 25GB, causing Vodafone to disable the SIM cards.

What's the best way to troubleshoot this?

Hello,

For a very basic view of currently active connections, WebUI has a Status -> Realtime Data -> Connections monitoring window.

A more detailed connections and traffic data can be obtained by installing Darkstat package. You can install it with the following commands:

• opkg update
• opkg install darkstat
• /etc/init.d/darkstat enable
• /etc/init.d/darkstat start

Then open your browser and enter routers IP with added 667 port. For example:

• 192.168.1.1:667

Host section can provide quite detailed statistics on each IP address monitored by the application.

Alternatively, you can install TCPdump from Services -> Package manager, enable monitoring for mobile wwan0 (mob1s1a1_4) interface and download packet capture file later from the same page.

Data here should provide sources of data consumption.

Best regards,
