在CentOS上监控Golang应用可以通过多种工具和方法实现,以下是一些常用的方法和工具:
wget https://github.com/prometheus/prometheus/releases/download/v2.36.1/prometheus-2.36.1.linux-amd64.tar.gz tar -xf prometheus-2.36.1.linux-amd64.tar.gz cd prometheus-2.36.1.linux-amd64 ./prometheus --config.file prometheus.yml
wget https://dl.grafana.com/oss/release/grafana-9.3.2.linux-amd64.tar.gz tar -xf grafana-9.3.2.linux-amd64.tar.gz cd grafana-9.3.2.linux-amd64 ./bin/grafana-server
prometheus.yml
中添加配置,例如监控Golang应用的指标端点:scrape_configs: - job_name: 'myapp' static_configs: - targets: ['localhost:8080']
import ( "net/http" "github.com/prometheus/client_golang/prometheus" "github.com/prometheus/client_golang/prometheus/promhttp" ) var ( requestCount = prometheus.NewCounter(prometheus.CounterOpts{ Namespace: "myapp", Name: "http_requests_total", Help: "Total number of HTTP requests", }) requestLatency = prometheus.NewHistogram(prometheus.HistogramOpts{ Namespace: "myapp", Name: "http_request_latency_ms", Help: "Latency of HTTP requests in ms", Buckets: prometheus.DefBuckets, }) ) func main() { http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) { requestCount.Inc() requestLatency.Observe(float64(time.Since(time.Now()).Milliseconds())) w.Write([]byte("Hello, world!")) }) http.Handle("/metrics", promhttp.Handler()) http.ListenAndServe(":8080", nil) }
通过上述方法,您可以在CentOS上有效地监控Golang应用,确保其性能和稳定性。
