I’ve entered the app ./launcher enter app and run the command apt install net-tools It no work. I tend to leave the discourse setup as is but I need to look into recently increased server load (user demand uptick), and so assumed I needed to enter the app and run netstat. Apparently it is not installed by default nor can I install it. This is a fairly rookie question I know I’m missing something very obvious here. Maybe I don’t need to be in the app?

Why not install is at the host instead of the container? If you want to check the server load, it makes sense to do it at the host level.

Discourse containers are built using the app.yml template, and any required packages must be installed during the image build process (i.e., when running ./launcher rebuild app). Packages cannot be installed interactively from within a running container. As a result, common tools like net-tools (which provides netstat) are typically not included and cannot be easily added after the container is running. If you need netstat inside the container, you’ll need to add it to your app.yml and then rebuild the container.

I see and thanks for that insight. Well this is why I leaves things alone more or less in there. I’m not too familiar with that doing that at all only plugins and customisation of basic app.yml. Is there a guide on meta that covers more expansive app.yml adventures?

When you say host do you mean the OS / linux level? I have netstat on Ubuntu OS but I thought I needed it in the container (where all the magic happens right, with nginx etc) if I understand things correctly. As was trying to gauge if our droplet is having a similar even the same issue as this other user case Discourse overloaded real traffic or DDOS? 100% CPU usage despite of decent traffic and high specs server

Indeed, you need to install monitoring at the outer level. Think of the container as containment: the idea is that things inside the container can’t break things which are outside. But the outer level can see everything that’s happening on the inside. All the network traffic, CPU activity, memory pressure.

¿Por qué no instalarlo en el host en lugar del contenedor? Si quieres comprobar la carga del servidor, tiene sentido hacerlo a nivel del host.
