apache/skywalking#1937

我们应用中使用skywalking中遇上一个异常，这个异常不定时出现。出现时的场景大概是这样的，asp.net core应用，在一个mvc的action中使用HttpClient/HttpWebRequest去发起一个http请求，发起的http请求就会报错，具体异常信息如下。

Hi all.

SkyWalking has a place to share with community with articles, speeches and videos related to SkyWalking and its ecosystem.

https://github.com/OpenSkywalking/Community

I think your people have some things to share.

这些不应该在一个TraceId里面吗？不然我怎么追踪一系列的操作？

netcore2.0中，api请求中head里面带有Authorization 时候追踪不到请求记录，不带Authorization 的时候就可以追踪到

Ocelot网关集成sk后端的服务不能发现

NetCore集成SK使用httpClientFactory调用api出现异常

HttpRequestException: Request headers must contain only ASCII characters.

System.Net.Http.HttpConnection.WriteStringAsync(string s)

如果把Startup中的SK代码注了就能正常运行

 public async Task<string> A()
        {
            var client = _httpClientFactory.CreateClient();
            client.BaseAddress = new Uri("http://127.0.0.1:9000");
            client.DefaultRequestHeaders.Add("charset", "utf-8");
            string result = await client.GetStringAsync("/api/service2/values");
            return result;
        }

I'm using skywalking in docker,and exposed the ports:10800、11800、12800.

When I start the sample project of skywalking-netcore,it fails at the first connection,and the follows connections are ok,as below:

But it can not work to send trace data to Skywalking.
I debugged the code ,and find that the state of the Channel is alwayes Idle,and Application can not registerd.

It may be something wrong with my environment,but I really can't solve the problem.
So,could you master give a help?
Thanks a lot!

In the CLR, the profiling API is used to write a code profiler, which is a program that monitors the execution of a managed application. We can use the JIT recompilation methods in the ICorProfilerCallback4 interface, to insert SkyWalking's tracing logic in the target method. For SkyWalking .NET Core Agent, this will be a very important change, realizing automatic proxy means that SkyWalking-NetCore will be comparable to some commercial APM products.

It is possible that configuration is not through appsettings.json, but through configuration center.

Currently our sampling mechanism only supports match the first N trace segments in the certain time window. But in some cases, we want to get more balanced sampling, such as percentage-based sampling, so we need to restructure SamplingService to provide multiple sampling implementations for the user to choose.

Hello there,thanks for your great job.
We have a case that all our requests point to only one controller and action,something like "http://ip:port/Common/Service",and we use reflection to invoke special method depending on parameters provided by HttpRequest body.
So it causes a thing that in SW UI,all request uri are like the same,except the ip and port.
And it is hard to find out the invoke trace easily.
It can be solved by seperate the controller and action for each api,but we have lots of old codes and it's too hard to do this.
So is it possible that we have a chance to modify the request uri before setting the Tags.Url？
Maybe something like a Func?
Please think about the case ,thanks!

• I want to have an externally configurable property in EnrtySpan to specify to ignore this request.

When I reimplement HostingDiagnosticProcessor, I can use some rules to determine if it is necessary to record the request.

Get the Custom Attribute on the Action through the ActionDescriptor in Microsoft.AspNetCore.Mvc.BeforeAction. It is logged when there is a Custom Attribute, and the Min Duration can be defined in a Custom Attribute. If it is lower than this threshold, it will be ignored.

So I may also need to have a property to access Span's EndTime or Duration.

There is a situation that we have many nodes would submit the data to central service, there were be slowly or fast, we did't found the slowly request where does it from? Why does it be slowly?

If we can collect the original datas from request, the client ip, that it will be a easy way to improve our system.

Otherwise, we are also like to collect the stacktrace when a exception thrown.

Sincerely hope that features will be provided.

Best wish to Skywalking Team!

Question

• What do you want to know?
  Why you design and use non-thread-safe class members such as ContextManager.StopSpan,
  which will crash production business code by throwing a InvalidException with message "no active span"

I suggest to register your internal components with scoped lifestyle to the DI,
then create scope for every context and use them.

Do you have any plan to support collect some basic info in the future? Like cpu, memory, io, GC eg..

If it's public, we can install SkyWalking. Agent. AspNetCore via the nuget package, use services.AddSkyWalkingCore () in ConfigureServices.

public void ConfigureServices(IServiceCollection services)
{
	services.AddSkyWalkingCore();
	services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}

skywaliking 可以设置哪些请求不需要追踪吗？比如以下的
向注册中心拉取服务列表
向配置中心拉取配置
向各基础组件发送心跳等

hi friends , it's a great soft,
now ,i have a problem :'no space left on device'

Add logging module to record internal events of agent.

TLS is very helpful when you want to uplink data through Internet. TLS has support in Java agent, doc: https://github.com/apache/incubator-skywalking/blob/master/docs/en/TLS.md

A large number of offline services in our current project are using rabbitMQ. Now C#/.NET instrument agent does not support common queues. I hope skywalking's netcore agent can support this.

在windows下安装agent，指令如下：dotnet skywalking install

Sync apache/skywalking#1181

This requirement came from the upgrade, SkyWalking's agent and protocol are stable enough, and didn't need to update for a long time. But considering right now, there are a lot of buffer in agent, so end users must reboot the monitored applications to upgrade backend, which caused by backend upgrade is not forward-compatible.
By having this feature, the backend break upgrade should be:

1. Stop all backends.
2. Clear the ElasticSearch data.
3. Set all flush file to true, and wait all agents refreshed and updated the new refresh time.
4. Start up new version collector.
