2) 已经安装 kindling-agent,v0.91; 下载运行skywalking7.0.0的oap、web-service, demo-app, agent。运行demo加入agent、oap、web-service。
skywalking是非容器版
3）已经下载编译 async-profiler(1.0.2)、kindling-java-agent(1.0.3)。尝试运行 ./profiler.sh start demo的oid、./profiler.sh start oap的pid，均提示如下类似的信息
[Exist File] /proc/48071/root/tmp/kindling

4) 在浏览器访问skywalking正常，访问 kindling-camera的 http://192.168.5.21:9504，选择一个服务，总是提示 未检测到trace探针。
在官网、github、网络、问chatgpt都没有明确的帮助说明。

需要怎么搭建这部分的环境？

看到这种容器是Prometheus，是Go语言程序，固定会出现这个提示。但是不影响使用，点击“复杂视图”可以看到profiling。
能否在应用列表里找到oap和demo？这两个程序也会出现这个问题吗

界面上没有看到demoapp的服务，这个问题一直卡在那里。

可以试试卸载skywalking agent，然后用页面上的“立即自动安装”

[gweichao]

我是直接选择、下载skywalking发布版本，跑 demoapp + agent、oam、web-ui服务，没有使用容器方式。这样不能跟kindling对接吗？
demoapp启动参数

/home/install/jdk/jdk1.8.0_381/bin/java -Dskywalking.agent.service_name=demoapp-lab-39 -Dskywalking.collector.backend_service=127.0.0.1:11800 -javaagent:/home/install/skywalking/agent-8.10.0/skywalking-agent.jar -jar lab-39-demo-2.2.2.RELEASE.jar

skywalking那边是可以看到请求业务的

[dxsup]

kindling这边是根本看不到这个服务，还是能找到这个服务但是仍然提示没有安装探针？

[gweichao]

根本看不到，估计是kindling需要容器方式安装的skywalking：

[gweichao]

花了几天研究部署skywalking 容器版，后端8.9.1，agent 8.9.0
kindling还是看不到请求，而且提示未检测到tracing探针。

详见截图。需要给skyw挂一个 skywalking java agent吗？

[dxsup]

不需要，只要skywalking安装上去了，能连通OAP就行。
kindling里面应该能看到lab-demo才对，不行的话，重启kindling-agent试一下。

[gweichao]

下面这个正确了吧？应该点击第一个？

skywalking解决初始化失败、elasticsearch集群异常/分片超限等问题后，通过sidecar加载demo镜像，临时在demo的容器建立隧道连接oap，现在看到demo，点击也不提示检测不到tracing探针了。

[dxsup]

这个对了，然后出现这种空的情况时，可以尝试重启一下kindling-agent，然后再发起请求看下数据
