The following list describes the reasons for upgrading the CloudMonitor agent:
The version of the CloudMonitor agent is continuously iterated to provide new features, fix stability issues, and optimize performance. If the CloudMonitor agent is not upgraded for a long period of time, stability issues may occur and your business is affected. For example, memory leaks may occur.
