I was trying to make something happen here and found that:

1. Either we don't have access, or the reported URL is not the correct one: https://loki-frontend-opf-observatorium.apps.zero.massopen.cloud/
2. Loki, the server used for aggregating data, expects to be loaded via REST invocations. Here we have multiple options:
3. To control our loggers to send to that specific endoints with the correct format
4. To use companion sidecars deploying a specialized tool called Promtail that scrapes stdout of the main container and act as forwarders to the process that aggregates data

This is probably a better example than the official Loki one to understand how to configure it with Promtail: https://www.giantswarm.io/blog/grafana-logging-using-loki

OK this is great info. I think (4) is our best bet. I don't think we want to configure app loggers to make REST calls unless there's no other way. The platform should always scrape stdout and report as appropriate (IMO).
