Sentry 是一个开源的非常强大的实时异常收集系统，可以为开发者的提供帮助、诊断，修复和优化其代码的性能的能力，可以用它来监控线上服务的健康状态，实时收集的异常堆栈信息可以帮助我们快速发现、定位和修复问题。
1. 安装使用
1.1 安装
| 1 2 3 | git clone https://github.com/getsentry/self-hosted sentry sudo ./install.sh sudo docker-compose up -d |

# 确认下docker和docker-compose版本是否满足
sudo curl -L https://github.com/docker/compose/releases/download/v2.7.0/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
1.2 创建项目
- 访问9000端口，创建用户，这时候一定要放开注册。
- create project
- Go 项目
1.3 配置邮箱
| 1 2 3 4 | sudo docker-compose down sudo docker-compose build –force-rm sudo docker-compose run –rm web upgrade sudo docker-compose up -d |
进入页面，在左上角的你的昵称位置单击，选择Admin。
然后在左侧选择Mail，然后在最下面有一个测试设置。点击“向送一封测试邮件”。如果收到的话，那么说明就配置成功了。
2. 代码
2.1 添加中间件
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | import sentrygin “github.com/getsentry/sentry-go/gin” appEngine.Use(sentrygin.New(sentrygin.Options{})) appEngine.Use(sentry.CaptureSentryMiddleware) func Init() { //TODO: DSN 配置 err := sentry.Init(sentry.ClientOptions{ Dsn: “http://1ccf51b1319f49c48e95cb56b7dc8fc4@192.168.40.98:9000/2”, // Set TracesSampleRate to 1.0 to capture 100% // of transactions for performance monitoring. // We recommend adjusting this value in production, TracesSampleRate: 1.0, }) if err != nil { lqlog.Info(“sentry init err:%v”, err) return } return } |
