Upgrading the Agent on a Linux Server

If the Agent of the early architecture cannot meet the requirements, you can upgrade the Agent. The Cloud Eye Agent will be continuously upgraded to provide you with a better monitoring experience. The following describes how to upgrade the Agent of an early architecture (Telescope) to that of the new architecture (Uniagent) on the Linux OS.

Procedure

Log in to an ECS as user root.
Run the following command to check whether the current Agent is using the Uniagent or Telescope architecture:
```
if [[ -f /usr/local/uniagent/extension/install/telescope/bin/telescope ]]; then /usr/local/uniagent/extension/install/telescope/bin/telescope -v; elif [[ -f /usr/local/telescope/bin/telescope ]]; then echo "old agent"; else echo 0; fi
```
- If old agent is returned, the Agent of an early architecture (Telescope) is used.
- If a version is returned, the Agent of the new version (Uniagent) is used.
- If 0 is returned, the Agent is not installed.
Uninstall the Agent of the current version.
- Early version: Run the command in Uninstalling the Agent (Early Version).
- New version: Run the command in Uninstalling the Agent (Early Version).
Install the Agent of the latest version by running the command in Procedure.
