Monitoring Agent
The monitoring agent is an auxiliary agent program independently developed and open-sourced by the platform. Installing the monitoring agent in the cloud host or physical cloud host can enable resources to work better with the cloud platform monitoring system, thereby expanding the monitoring depth of resources and enriching monitoring indicators (such as memory, disk space, processes, etc.).

Comment：
- If you need to use the Linux intranet data reporting version, please reinstall the agent; umagent now supports physical cloud hosts. If there is an error after installation, please resolve the dependency according to the error message.
- The monitoring agent only supports kernel versions below 4.18. Using kernels 4.18 and above in conjunction with UMA may result in the inability to obtain some indicators.
2.Preparation for Monitoring Agent Installation
- The installation process requires the use of system administrator users (such as root, administrator, etc.).
- The installation process needs to be carried out in the internal network environment of UCloud UHost.

Comment： Install the uma installation package for py2 or py3 according to the default python version of the current system. If the installation fails, you can try to install the other version.
