flowchartsman opened a new issue #9772: URL: https://github.com/apache/pulsar/issues/9772
Currently Go function metrics are implemented with a Prometheus registry and [instantiated at runtime in an init()](https://github.com/apache/pulsar/blob/206ea82e012af34c5bb7f824826205019f3dd4ff/pulsar-function-go/pf/stats.go#L57-L150). These metrics are exposed to the functions runtime and automatically updated by the SDK, which makes sense, but the registry is inaccessible to the user. It would be great to be able to support something like `recordMetric` as [provided to the Java SDK](https://pulsar.apache.org/docs/en/2.4.0/functions-metrics/) A simple implementation could be to mirror this and provide a `context.RecordMetric(metricname string, value float64)`, though we could also provide package-level functions to create and register new metrics by name, like `pf.NewGauge(name string) (prometheus.Gauge, error)` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
