New Inspections¶

• Cloud Idle Resource Inspection: As cloud computing rapidly develops as a new IT service model, it provides convenient, fast, and elastic IT infrastructure and application services for enterprises and individuals, bringing high efficiency and economy. However, with cloud resources becoming a major part of enterprise data centers, significant waste of cloud resources has become increasingly prominent. Especially within enterprises, due to demand fluctuations and departmental isolation, some cloud resources are not fully utilized, forming a large number of idle resources. This situation can lead to rising cloud service costs, decreased resource efficiency, and reduced security and performance levels. To better manage and optimize idle cloud resources and improve the utilization and efficiency of cloud computing, conducting idle resource inspections is essential. Through inspections, unnecessary resources in current cloud services can be discovered and handled promptly, avoiding unnecessary expenses, data leaks, poor performance, etc.

• Host Reboot Inspection: Host abnormal reboot monitoring is an important aspect of modern internet system operations. On one hand, the stability and reliability of computer systems are crucial for smooth business operations and user experience. When hosts experience abnormal reboots, risks such as system crashes, service interruptions, and data loss arise, affecting business operations and user satisfaction. On the other hand, with the increasing number and scale of hosts in cloud computing and virtualization environments, system complexity and the probability of issues increase. System administrators need to use relevant monitoring tools for real-time monitoring and timely discovery and resolution of abnormal reboots. Thus, properly implementing host abnormal reboot monitoring helps businesses diagnose problems quickly, reduce business risks, enhance operational efficiency, and improve user experience.
