ERROR,com.alibaba.chaosblade.box.service.collect.CollectorTimer - collect container fail! #48

Access: box的log报这个错误, kubeconfig应该有最高权限了. 场景是部署了chaosblade-box, 通过k8s获取pod等相关信息 信息是能获取的, 但稍等一会, 感觉轮询的时候就会报这个错误.

用rancher的api, 和直接的k8 api都报错:

Log detail:(rancher) 2021-07-01 11:41:58.356, ERROR, [OkHttp https://rancher.cn.nonprod/...] com.alibaba.chaosblade.box.service.collect.CollectorTimer - collect container fail!

rancher的kubeconfig:

apiVersion: v1
kind: Config
clusters:
- name: "performance"
  cluster:
    server: "https://rancher.cn.nonprod/k8s/clusters/c-65jpj"

current-context: "performance"

k8s 源生kubeconfig:

apiVersion: v1

    api-version: v1
    certificate-authority-data: LS0...0K
    server: "https://whdrcsrv220.cn.nonprod:6443"

    client-key-data: LS0...LS0tCg==

目前的workaround就是不做experiment的时候 "关闭采集"

有详细的错误调用栈信息吗

经开发初步排查, 日志问题基本定位了，是探针采集的时候，发请求太凶猛导致k8s的api server cpu打满。

能否暴露频率参数, 运行jar的时候进行调整 --
拿到node列表后，每隔30秒就轮询每个node上pod 再每30秒轮询每个pod上container

同遇到类似问题， 这样的话，确实看到apiserver cpu使用率爆了，这样岂不是对apiserver 压力过大。。
