Trying to make it short:

1. I use a switch (TP-Link TL-SG108E) that mirrors all traffic from my router to Raspberry Pi running ntopng traffic monitor app.
2. ntopng has almost everything I want except detail DNS requests monitoring. To do that, I send my router's DNS requests log to a syslog server on Raspberry Pi, which is processed using a custom Java app I created. Note: My router (D-Link DIR-868L) uses custom firmware (Tomato) that can send its syslog to a remote server.
3. I wrote another custom Java app to find out device names using data from both ntopng and my router's DHCP lease.
4. Data from both ntopng and my custom processed data displayed on Grafana dashboard as in the screenshot.

Luckily I have sufficient technical skills to pull this off. Most people would simply buy a high-end router or setup Ubiquiti Unifi system. Very glad to be able to do this

This should be the main issue why the Internet is quite slow these past few days. Since it is already public, I'm actually aware of this and the fault actually occurred at 11am on 8th April 2020, which is two days ago.  I'm a network engineer working in an enterprise MNC that are involved in maintenance and configuration of IPLC services for enterprise clients, and we get direct updates from the companies that manage these subsea cables, so I do know the inside scoop.

Anyway, since then, traffic have been affected for our clients, both local and international. It is no surprise that home users would be affected too. ETR will usually take about two to three weeks. Just wait till it is better, and hope that there is no delays. Per the article, they have rerouted the circuits, but it won't be as fast.

Why dont you just call TM to come change the Modem for free?
