Is this library still alive? #94

Open mickel8 opened 2 years ago

Hi, just wanna ask a question if you are going to maitain this library and if no -- why?

It looks so nice but the last update was 4 years ago. Also, the issue with cowboy and removed sha1 function (#93) seems to not be resolved.

Hi @mickel8, Over the years I was exploring methods of BEAM observation and visualisation. This project is one of somewhat complete prototypes. We use it for teaching Erlang, as it help students to visually think about concurrency and distribution. It is helpful when they start learning BEAM.

This project was not optimised enough to support heavy live systems, which I used to work with a lot. My job required me to think about methods more suitable for long running distributed applications.

I continue to research techniques and tools under the @erlanglab organisation. If you have a specific use case for erlangpl, please describe it here.

If you would be willing to help fix the issues you mentioned, I will be very glad to assist you or merge a PR.

Have a good day!

Hi @michalslaski, I am sorry for the quality of my first message. I have no idea why it was so messy (fixed it a little bit).

I wanted to try erlangpl to observie multimedia processing pipelines. There is Membrane Framework where we are constructing pipelines that consist of a lot of processes linked together. Each process is responsible for manipulating data in a different way e.g. one process will interpret header of incoming packet while the next one will interpret its payload.

We are also developing own tool for monitoring Membrane but I was curious how erlangpl will visualize it. erlangpl provides also system information like memory which is also very useful.

According to performance, we have very similar problems :slightly_smiling_face:

I will try to update this repository a little bit and make a PR.

Thanks!
