Question 1

How to add fiberprometheus to a Fiber app?

Accepted Answer

Import the package, create an instance with your service name, register the middleware using app.Use(), and set up the metrics endpoint with RegisterAt(). The README example shows it can be done in under 10 lines of code.

Question 2

fiberprometheus vs standard Prometheus Go client for Fiber?

Accepted Answer

fiberprometheus is tailored for Fiber with pre-configured HTTP metrics and easy setup, while the standard client requires manual instrumentation for similar metrics. Choose fiberprometheus for quick Fiber integration, but use the client directly for custom or advanced metrics.

Question 3

Can I track database queries with fiberprometheus?

Accepted Answer

No, fiberprometheus only handles HTTP metrics like request counts and latency. For database or custom metrics, you need to use the Prometheus Go client library separately alongside this middleware.

Question 4

How to skip health check endpoints in metrics?

Accepted Answer

Use the SetSkipPaths method to specify paths like "/ping" that should be excluded from tracking, as demonstrated in the README example to prevent noise from frequent health probes.

Question 5

Is the /metrics endpoint secure by default?

Accepted Answer

No, fiberprometheus does not include authentication or encryption for the metrics endpoint. You must manually secure it, e.g., by adding Fiber middleware for basic auth or IP whitelisting.

Question 6

What happens if I use an unsupported Go version?

Accepted Answer

fiberprometheus requires Go 1.22 or above, as stated in the README. Using an older version will likely cause compilation errors, forcing an upgrade or alternative solutions.
