Strange Traffic Problem

upgrade81 · Mar 10, 2019

Hi everyone,
it's been a few days since I've migrated a site to a new vm.
With top2 or bmon I see constantly in use from 20 to 100mb/s of bandwitch.

I have already used ngxtop but it does not show anything unusual.
Can you tell me if there is a more granular tool?

I can not individualize that files are doing so much traffic.
:-(
Thank you

Ok I solved, I have enabled the static file log in /usr/local/nginx/conf/staticfiles.conf
Relaunched ngxtop
and I saw it was a customer's mp4 video.

Does anyone know a good hosting to host some videos?

Youtube ? Unfortunately, if you're hosting customer sites you would have to anticipate them uploading videos to your servers and spec your hosting accordingly.

it's just a friend's site.
Unfortunately it is a video that serves to monetize in preroll, so no youtube or vimeo.

how large is the video ? you can probably optimize it's size = smaller = less traffic/bandwidth used

if it's a once off video you can highly optimise it's size i.e. Better web video with AV1 codec — Martian Chronicles, Evil Martians’ team blog

Meet AV1
AV1 is a video codec that was first released almost a year ago: in March 2018. It is designed to compete with previous codec generations such as HEVC/VP9 and H.264/VP8.

To get familiar with technologies used in a new generation video code, feel free to read “Introducing AV1” and “AV1: next generation video”.

With all the low-level trickery involved, AV1 is capable of generating files that are up to 30-50% smaller than H.264/VP8 and up to 30% smaller than HEVC, even though, due to being still mostly experimental, it has some problems (at the time of this writing):

The encoder is not optimized yet. As a result, encoding is extremely slow (an upcoming encoder written in Rust attempts to solve this issue). The format is not yet ready for live streaming. However, it is perfectly suitable for web, as your average landing page will usually have a short embedded video that rarely changes.

While supported by Chrome and Firefox, AV1 lacks implementations for Safari and Edge (although Microsoft already has AV1 support in early beta). So you need to have at least two versions of all your videos: AV1 for Chrome/Firefox and H.264 for everything else. Ideally, you should have a third, HEVC version for your Safari users on desktop and mobile and we will show how to prepare all three of those files.

The central promise for of AV1 is maintaining high image quality even at low bitrates, thus allowing for smaller files without apparent compression artifacts.
