Golang、Redis 事务并没有显示在新的遗迹面板中

Golang 中的新 Relic 事务追踪功能在 Redis 事务中并未正常显示。开发人员遵循了文档和示例，但在将事务和段传递给 Redis 客户端时遇到了问题。他们尝试了使用执行上下文、后台上下文和当前事务上下文，但数据库事务仍然没有出现在数据库部分中。查询已执行，但没有报告任何数据。

所以...我已经在这个问题上坚持了几天了，我遵循了文档和梨的建议，但似乎不起作用，我正在将 golang 与 grpc 结合使用，并在其中实现一个新的遗迹，为了跟踪事务和整体性能，我设法声明事务和段，但就数据库事务而言，它们没有出现在数据库部分中，我尝试在执行以下操作时将新的遗迹上下文传递到 redis 客户端事务，也尝试使用后台上下文和当前事务上下文，但似乎不起作用。已进行查询但未报告任何数据 这是我所拥有的示例

1 - 进行交易的函数之一

// updatecache ...
func updatecached(data *statemachinepkgv1.statemachine, sessionid string, ctx context.context) (*statemachinepkgv1.statemachine, error) {

    //transaction and segment logic
    
    //this does not create a brand new relic application, just gets the main instance
    relic, err := tools.initrelic()

    if err != nil {
        log.fatalf("failed to create/instace newrelic.newapplication: %v", err)
    }

    txn := relic.starttransaction("redis", nil, nil)

    defer newrelic.startsegment(txn, "updatecached").end()
    defer newrelic.startsegment(tools.currenttransaction, "updatecached").end() //tools.currenttransaction has the context of main web transaction stored with singleton design

    defer txn.end()

    dataparse, err := json.marshal(data)
    if err != nil {
        return data, err
    }

    duration, err := time.parseduration(os.getenv("go_statemachine_redis_timelife"))
    if err != nil {
        return data, err
    }

    //redis logic
    dbtransaction := newrelic.fromcontext(ctx)
    newreliccontext := newrelic.newcontext(context.background(), dbtransaction)

    err = masterclient.set(newreliccontext, sessionid, string(dataparse), duration).err()

    if err != nil {
        return data, err
    }

    return data, nil

}

感谢您的帮助，非常感谢！

正确答案

最后通过更新所有依赖项修复了问题，必须升级 grpc 版本及其各自的依赖项。

还可以更改 redis 事务使用的上下文。

这是最终的代码

1 - 函数使用示例

dbtransaction := newrelic.fromcontext(ctx)
    newreliccontext := newrelic.newcontext(context.background(), dbtransaction)

    data, err := tools.client.get(newreliccontext, id).result()

2 - redis 单例

package tools

import (
    "context"
    "os"

    "github.com/go-redis/redis/v8"
    nrredis "github.com/newrelic/go-agent/v3/integrations/nrredis-v8"
    newrelic "github.com/newrelic/go-agent/v3/newrelic"
)

var redisopt = &redis.options{
    addr:     os.getenv("****************") + ":" + os.getenv("*****************"),
    db:       1,
    password: os.getenv("******************"),
}

var client *redis.client = nil
var ctx context.context = nil

func gettransaction() *newrelic.transaction { return nil }

func init() {

    client = redis.newclient(redisopt)
    client.addhook(nrredis.newhook(redisopt))

    txn := gettransaction()
    ctx = newrelic.newcontext(context.background(), txn)
}

func getredis() (*redis.client, context.context) {

    if client == nil {
        client = redis.newclient(redisopt)
        client.addhook(nrredis.newhook(redisopt))

        txn := gettransaction()
        ctx = newrelic.newcontext(context.background(), txn)

    }

        }

        return RelicApplication, err

    } else {

        return RelicApplication, nil
    }

}
