Better Network observability in Coroot
One service can’t connect to another (or can’t establish a database connection) – underneath this simple definition, there can be two very different conditions. First – we may have a service process down. In this case, the Kernel stack is operational, so we are getting the packet back, indicating the connection was refused. Second – when network flow is completely disrupted due to connectivity issues, firewall, or a node being completely down.
