Just trying out the Studio Code Server add-on.
I’m aware that it uses a lot of resources, but its memory usage seems to be creeping up slowly and staying high even when I’m not using it. Is this normal behaviour?
The add-on was installed on January 9 and I stopped it running on 14 and 15 Jan (the drop today is me installing 2025.1.2).
I’m running HA on an i3 PC with 8 GB RAM
Yeah. I shut it down when not using it.
Can’t find the GitHub URL, but there was a huge issue about the Studio Code Server addon memory usage.
Came here because of
Older issues:
I suspect that for each session that you use Studio Code server it will reserve some memory and not release it. If you edit on different tabs / browsers / computers it will add up. As you can see in the memory usage graph (sensor.memory_use_percent) below the memory usage went down from 92% to 38%, more than half the memory on my system, this was when I did a restart of the Studio Code server. Just before the restart, I started a new session and memory usage went up to above 92%. On Aug 10 around 21:00 I started an other session where I opened multiple files, and the usage went from 70% to almost 90%, and this was never released.
It would be nice if we could see the amount of memory that this addon is using, so that we could have an automation send a message if the memory usage is too high. For now, I will make an automation that warns me if the HASS OS memory is above 90%, so that I can restart the studio code.
Nah, instead of workarounds (which I have in place already for a long time) the addon should just behave nicely out of the box in terms of resource usage.
A timeout after which resources are released would be the usual behavior. Or a switch to not store the session (for longer than X minutes/hours). The core issue is that currently it just never releases allocated memory resources.
I agree, the addon should behave nicely, but as long as it doesn’t…
By the way, it affects cpu usage as well. When I start more sessions, cpu usage goes up and stays up. After reset of addon, cpu usage stays low.

You can when using HAOS: Go to settings, integrations, supervisor and enble the memory and cpu entities for addons you want to monitor. Then create an automation if it exceeds your wishes, or put them in a graph:
Well the addon also eats a lot of SWAP space and that is not available to monitor on an addon basis.
The default update interval for the supervisor addon entities by the way is 5 minutes.
