os：Ubuntu 2204
ob: 4.2.0

背景：
因为某些原因，无法再Ubuntu2204上通过obd安装部署observer、obagent
现在手工方式安装observer、obagent，目前observer已经是正常的，但是部署obagent的有问题。

#  cat  conf/monagent.yaml

启动：

# bin/ob_monagent -c conf/monagent.yaml >> ./log/monagent_stdout.log
复制

验证：

# curl --user admin:root  http://10.x:8088/metrics/ob/basic

复制

为什么会报错呢？
