I've been struggling with API observability for a while now, and it's been a real headache. Initially, we set up Prometheus and Grafana, but they only track infrastructure metrics. So when something goes wrong, we get alerts about high CPU usage or spiking memory, but no clue about which specific API endpoint is causing issues. To tackle this, I built custom Grafana dashboards to monitor request counts and latencies per endpoint, which helped a bit, but I still can't correlate errors between services effectively. I added distributed tracing with Jaeger for post-mortem debugging, but it's not helping in real-time. I also integrated Gravitee for gateway-level visibility, which gives metrics and errors per endpoint, but now I'm just overloaded with data without a clear overview.
Currently, I'm struggling with:
- Zero visibility on Kafka events and no way to know if consumers are failing.
- Inability to connect frontend errors with backend API failures.
- Increasing alert fatigue.
- Lack of a baseline to determine what "normal" looks like, making every spike feel like a crisis.
It feels like I'm just piling on tools without really fixing anything. How do you handle API observability in a microservices architecture? Am I missing something obvious, or is this just part of the chaos?

Have you tried using the BlackBox Exporter? It allows you to check whether your API is functioning correctly by crafting specific requests. It could give you the visibility you need on API health.
You know, sometimes I just pretend to understand everything until people forget about the last performance issue. It’s not the best strategy, but it keeps things moving for now!
If you're missing API health checks, adding a client library for Prometheus could really help. Just make sure to check their best practices for naming—it's crucial for keeping things organized.
I really recommend looking into Postman's tools, especially Postman Insights. It can give you a clear picture of your API's performance, even if you don't decide to purchase it. Also, consider exploring concepts like semantic monitoring and synthetic transactions, which can help you test user journeys directly against production APIs.
Have you thought about integrating with an observability platform like DataDog? It can provide meaningful insights and improve your API monitoring significantly.
