在Golang中实现跨平台的日志实时告警,可以通过以下几种方式实现:
package mainimport( "log" "os" "time" "github.com/hpcloud/tail"// 跨平台文件跟踪 "github.com/robfig/cron"// 定时任务)func setupLogMonitor(logPath string){ t, err := tail.TailFile(logPath, tail.Config{ Follow:true, ReOpen:true, Location:&tail.SeekInfo{Offset:0, Whence: os.SEEK_END}, }) if err !=nil{ log.Fatal(err) } for line :=range t.Lines { if shouldAlert(line.Text){ sendAlert(line.Text) } }}func shouldAlert(logLine string)bool{ // 实现你的告警逻辑,如匹配错误关键词 return strings.Contains(logLine,"ERROR")|| strings.Contains(logLine,"FATAL")}func sendAlert(message string){ // 实现告警发送逻辑,如: // - 发送邮件 // - 调用Webhook // - 发送Slack/Teams消息 log.Println("ALERT:", message)}>> goland Ai Assistant 插件获取 <<
package mainimport( "log" "log/syslog")func setupSyslogAlert(){ sysLog, err := syslog.New(syslog.LOG_ALERT,"myapp") if err !=nil{ log.Fatal(err) } // 重定向标准日志 log.SetOutput(sysLog) // 自定义告警 log.Println("Application started")// 普通日志 sysLog.Alert("Critical error detected!")// 告警级别日志}package mainimport( "golang.org/x/sys/windows/svc/eventlog" "log")func setupWindowsEventLog(){ el, err := eventlog.Open("MyApplication") if err !=nil{ log.Fatal(err) } defer el.Close() el.Info(1,"Application started") el.Error(2,"Critical error detected!")}package mainimport( "github.com/fsnotify/fsnotify" "log")func inotifyLogMonitor(logPath string){ watcher, err := fsnotify.NewWatcher() if err !=nil{ log.Fatal(err) } defer watcher.Close() err = watcher.Add(logPath) if err !=nil{ log.Fatal(err) } for{ select{ case event :=<-watcher.Events: if event.Op&fsnotify.Write == fsnotify.Write { // 读取新增内容并检查是否需要告警 } case err :=<-watcher.Errors: log.Println("Watcher error:", err) } }}// 结合前面的Windows事件日志代码// 可以配置Windows任务计划程序对特定事件ID触发告警// 使用Prometheus客户端import( "github.com/prometheus/client_golang/prometheus" "github.com/prometheus/client_golang/prometheus/push")var errorCounter = prometheus.NewCounter( prometheus.CounterOpts{ Name:"app_errors_total", Help:"Total number of application errors",},)func init(){ prometheus.MustRegister(errorCounter)}func sendPrometheusAlert(){ // 当检测到错误时 errorCounter.Inc() // 推送到Prometheus Pushgateway err := push.New("http://pushgateway:9091","myapp_job"). Collector(errorCounter). Push() if err !=nil{ log.Println("Could not push to Pushgateway:", err) }}// 使用Elasticsearch Go客户端import( "context" "github.com/elastic/go-elasticsearch/v8")func sendToElasticsearch(logData string){ cfg := elasticsearch.Config{ Addresses:[]string{"http://localhost:9200"},} es, err := elasticsearch.NewClient(cfg) if err !=nil{ log.Fatal(err) } _, err = es.Index( "app-logs", strings.NewReader(logData), es.Index.WithContext(context.Background()), ) if err !=nil{ log.Println("Elasticsearch indexing error:", err) }}/ vs \)\n vs \r\n)以上方案可以根据实际需求组合使用,构建适合您环境的实时日志告警系统。
