In this case, if you had multiple containers, by default, when Prometheus came to read the metrics, it would get the ones for a single container each time (for the container that handled that particular request), instead of getting the accumulated metrics for all the replicated containers. You can easily expand on this core module to add other health checks for other services. Consequently most frameworks implement endpoints for the service as well as nested components (more about that later) conform to the Spring Actuator API: /actuator/health. Remove hot-spots from picture without touching edges. This wouldnt happen if you received a dict instead of a pydantic model: This way you can trigger autocompletion for all your data.

Ensure all the packages you're using are healthy and During development happen errors. This will be the main point of interaction to create your API. So, if your application consumes a lot of memory (for example with machine learning models), and your server has a lot of CPU cores but little memory, then your container could end up trying to use more memory than what is available, and degrading performance a lot (or even crashing). Then in the next (and final) stage you would build the image more or less in the same way as described before. This module does not contain any service checkers, but you can easily add them.
