Monitoring
Monitoring and Cloud Trail of KakaoCloud monitor Virtual Machine (VM) and analyze the traffic patterns to solve resource issues.
For monitoring, install the Monitoring Agent in advance.
Monitoring
KakaoCloud collects metrics, events, and logs of virtual machines through the monitoring service. With this service, you can configure time-series dashboards for these metric elements. By monitoring specified metrics and sending notifications if the metrics exceed the allowable range, you can ensure the system is performing as expected.

Cloud Trail
KakaoCloud Cloud Trail automatically collects and records user activities. It tracks user activities such as logins and resource creation, modification, and deletion on an event basis, allowing you to manage activity information. You can audit whether security policies are being complied with by viewing events from the past 90 days in the console. Additionally, you can check for recent activities in the project, and whether unauthorized users have accessed or worked on the project.
