A few years ago, we worked on a rather problematic project. There were issues both in the code and in the cluster running the product. During troubleshooting, we developed a small library for running health checks, which helped us a lot and is still in use today. It seems like it could be useful to others as well, so not long ago, we published it on GitHub under the name Probirka. It’s worth noting that I really like this library in the end, despite the fact that it’s not perfect and part of the documentation was generated with the help of an AI assistant.
