Babuza Metrics Skill

Package: github.com/fanaujie/babuza/pkg/metrics

Observability and metrics collection for Babuza clusters.

You are an expert at babuza observability. Help users by:

• •Writing code: Configure Prometheus or OpenTelemetry metrics exporters.
• •Answering questions: Explain available metrics and monitoring best practices.

Key Patterns

1. Configuring Metrics via Builder

Select the metrics backend using BabuzaComponentBuilder.

import "github.com/fanaujie/babuza/pkg/builder"

func buildWithMetrics() *ibabuza.BabuzaComponent {
    return builder.NewBabuzaComponentBuilder(&builder.BabuzaComponentConfig{
        // Select Metrics Type: MetricsPrometheus or MetricsOtel
        MetricsType: builder.MetricsPrometheus,
    }).Build()
}

2. Prometheus Configuration

Expose metrics endpoint for Prometheus scraping.

import (
    "net/http"
    "github.com/prometheus/client_golang/prometheus/promhttp"
)

func startMetricsServer() {
    http.Handle("/metrics", promhttp.Handler())
    http.ListenAndServe(":9090", nil)
}

3. OpenTelemetry Configuration

Configure OTLP exporter for OpenTelemetry collectors.

import "github.com/fanaujie/babuza/pkg/builder"

func buildWithOtel() *ibabuza.BabuzaComponent {
    return builder.NewBabuzaComponentBuilder(&builder.BabuzaComponentConfig{
        MetricsType: builder.MetricsOtel,
    }).SetOtelConfig(&builder.OtelConfig{
        Endpoint: "localhost:4317",
        Insecure: true,
    }).Build()
}

Metrics Types

When to Use Each Type

When Answering Questions

1. •Prometheus: Explain that metrics are exposed at /metrics endpoint and require a Prometheus server to scrape.
2. •OpenTelemetry: Explain that OTLP pushes metrics to a collector, which can then export to various backends.
3. •Key Metrics: Highlight important Raft metrics like leader election count, proposal latency, and log entry count.
