应用诊断

应用诊断介绍

基于阿里arthas对JAVA应用进行性能诊断，快速定位Java线上问题、可以在不重启JVM进程的情况下，查看程序的运行情况。线程耗时分析、方法执行分析和性能分析。

Warning

对需要诊断的应用Pod Annotation增加diagnosis: true字段

修改诊断网关配置文件

配置文件示例

  1. giraffe通过namespace定期上报Pod信息到鲁班运维平台，这里namespace支持配置多个

  2. 配置阿里云oss信息，创建内存快照、火焰图功能会将文件上传到oss

#giraffe:
# agent 以Sidecar运行在容器内
agent:
  port: 43439

# 阿里云oss AK
oss:
  accessKey:  ""
  accessSecret:  ""
  endpoint: "http://oss-cn-hangzhou.aliyuncs.com"
  bucket: "lubanDump"
  originDir: "headdump/"
  bucketDomain: "https://lubanDump.oss-cn-hangzhou.aliyuncs.com"

# controller监听端口及订阅的namespace
controller:
  port: 45459
  host: '127.0.0.1'
  # 上报namespace下的Pod信息, 多个命名空间以"｜"分隔、 示例： default|test|uat
  namespace: 'prod|uat'

auth:
  # 认证token
  token: '951ebc8e-15f1-48d3-af2d-b28def327067'
  # 运维平台地址
  url: 'http://127.0.0.1:8999'

启动giraffe-gateway

giraffe-gateway通过informer订阅Pod信息，giraffe-agent以sidecar方式运行在Pod内。诊断数据将通过rpc方式传输
