新文物与围棋的整合:我无法用新的文物来监控我的围棋项目。

Question

我无法用新的来监视go项目

我可以使用JAVA进行监控

我遵循文档步骤：https://docs.newrelic.com/docs/apm/agents/go-agent/installation/install-new-relic-go/

1. 来自 github.com/newrelic/go-agent，使用您的首选进程；例如： bash命令go get github.com/newrelic/go-agent/v3/newrelic
2. 在应用程序中导入github.com/newrelic/go-agent/v3/newrelic包。 import github.com/newrelic/go-agent/v3/newrelic
3. 通过在主函数或init块中添加以下内容初始化Go代理： newrelic.ConfigLicense("YOUR_NEW_RELIC_LICENSE_KEY")，:= newrelic.NewApplication( newrelic.ConfigAppName(“您的应用程序名称”))

注意:我也注意到了所有的问题解决方法。

main.go

package main

import (
    "fmt"
    "io"
    "net/http"

    "github.com/newrelic/go-agent/v3/newrelic"
)

var newrelicApp *newrelic.Application

func main() {
    app, err := newrelic.NewApplication(
        newrelic.ConfigAppName("MyAppMain"),
        newrelic.ConfigLicense("<YOUR_NEW_RELIC_LICENSE_KEY>"),
        newrelic.ConfigAppLogForwardingEnabled(true),
    )
    if err != nil {
        fmt.Printf("error is " + err.Error())
    } else {
        newrelicApp = app
        http.HandleFunc(newrelic.WrapHandleFunc(app, "/test", customEvent))
    }
}

func customEvent(w http.ResponseWriter, req *http.Request) {
    io.WriteString(w, "recording a custom event")

    newrelicApp.RecordCustomEvent("MyAppMainEvent", map[string]interface{}{
        "text":      "Hello VP",
        "env":       "go_local",
        "alertType": "error",
        "priority":  "Critical",
        "source":    "MyAppMain",
    })
}

您不必将应用程序存储在全局变量中并覆盖现有变量，这将导致问题，还需要启动web服务器。我更新了代码：

package main

import (
    "fmt"
    "io"
    "net/http"

    "github.com/newrelic/go-agent/v3/newrelic"
)

func main() {
    app, err := newrelic.NewApplication(
        newrelic.ConfigAppName("MyAppMain"),
        newrelic.ConfigLicense("280d644a5b4fc4859d5fa75b8897f4422bb5NRAL"),
        newrelic.ConfigAppLogForwardingEnabled(true),
    )
    if err != nil {
        fmt.Printf("error is " + err.Error())
    } else {

        http.HandleFunc(newrelic.WrapHandleFunc(app, "/test", customEvent))
    }

    http.ListenAndServe(":8090", nil)

}

func customEvent(w http.ResponseWriter, req *http.Request) {
    txn := newrelic.FromContext(req.Context())
    io.WriteString(w, "recording a custom event")

    txn.Application().RecordCustomEvent("MyAppMainEvent", 
    map[string]interface{}{
        "text":      "Hello VP",
        "env":       "go_local",
        "alertType": "error",
        "priority":  "Critical",
        "source":    "MyAppMain",
    })
}
