Great question Geert!
The first graph in the admin console represents the Elasticsearch container. Elasticsearch is responsible for indexing related clusters of data nodes to work together and respond to requests. We currently have 1 index per tenant, where the index is broken up into smaller segments in order to increase search efficiency. Elasticsearch is used abundantly in Jama and is expected to use more memory than most of our other containers.
The second graph in the admin console represents the Nginx container. Nginx is responsible for acting as a load balancing layer. It has a lightweight infrastructure because it it process driven, rather than event driven. Therefore, Nginx d
efines worker processes to serve requests, instead of spawning a new process for each request. That is why the memory usage represented on the Nginx graph is significantly lower than the Elasticsearch graph.
Hopefully this answered your question!

Subject: How to Interpret Memory Usage in Admin Console
A memory usage window in the admin console always has two graphs. Which one is the actual usage and what is the function of the other graph?
For instance, in the image included below, there is one graph that hovers around 7GB and one that is around 1.5GB. Which one represents the actual usage and what does the other value represent?

In the following image, there you can see that some values have changed:
