Version Upgrades

The Cloud Eye Agent collects OS-level metrics from the host, which is valuable for server monitoring. The Cloud Eye Agent will be continuously upgraded to provide you with a better monitoring experience.

Upgrade Cause

Causes for upgrading the Cloud Eye Agent are as follows:

The Cloud Eye Agent regularly updates to add new features, fix stability issues, and optimize performance. If the Cloud Eye Agent is not updated for a long time, some stability issues may occur, affecting services. For example, memory leakage may occur.
Due to different architectures, Cloud Eye Agents are available in both earlier and new versions. Some new versions (2.6.4.1 and earlier) and earlier versions (1.x.x) are no longer maintained. If you encounter any problem with the Cloud Eye Agent, upgrade it to the latest version. If the problem persists, submit a service ticket to contact customer service.

Pay attention to the version release information of the Cloud Eye Agent and upgrade it to the latest version. For details about Cloud Eye Agent versions, see Agent Features per Version.

Checking the Cloud Eye Agent Version

You can log in to the Cloud Eye console, choose Server Monitoring > Elastic Cloud Server or Server Monitoring > Bare Metal Server, and view Agent Edition in the server monitoring list.

If the Agent version is 1.x.x, the Cloud Eye Agent installed on the current host is of an earlier version.
If the Agent version is 2.x.x, the Cloud Eye Agent installed on the current host is of a new version.

If Agent Edition cannot be viewed in the server monitoring list, you can log in to the server to view the version of the Cloud Eye Agent.

Log in to the server as user root.
Run the following command to check the Agent version:
```
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 earlier version is used and the Agent version is 1.x.x.
- If a version number is returned, the Agent of a new version is used and the Agent version is 2.x.x.
- If 0 is returned, the Agent is not installed.
