[CollEc] CollEc App Offline

[Düben, Christian]

I indeed managed to restart it.

Simply restarting the Docker containers did not solve the problem. I had to entirely get rid of the containers and restart the Docker deamon itself. It looks like it started malfunctioning following some o/s change on December 23.

I am going to monitor the app over the next few days to see if any of the processes deviates from its expected behavior.

How are we going to handle the migration to Helos, by the way? As long as the server runs at 100 percent CPU load, it is going to be difficult to run and test anything on it.

Regarding GraphEc, I now plan on setting it up with a NodeJS backend rather than as a Shiny application with an R backend. Unlike CollEc, it does not require the functionalities of R or Python combined with C++. It exclusively reads pre-computed results from a SQL database and displays them. With front- and backend written in JavaScript, I can make use of pre-initialization. I.e. users do not have to wait for the app to initialize, as they do in the case of CollEc where ShinyProxy might take a few seconds to spin up a Docker container. However, I need to focus on my research during the week and only have time to work on my JavaScript skills and apps during the weekend. It might, therefore, take a few months to produce a satisfactory JavaScript GraphEc.

Thanks for looking into the CollEc app crash on a Sunday.

  Well it is now. I guess Christian started it.
