Operating System Console FAQ-Alibaba Cloud Linux(Alinux)-阿里云帮助中心

The Operating System Console provides management features to improve operating system performance. This topic answers the frequently asked questions (FAQs) about the Operating System Console.

Is the Operating System Console free?

The Operating System Console service is free. However, you are charged for the resources you use, such as bucket storage and Alibaba Cloud Simple Log Service (SLS).

Resource consumption of the persistent SysOM component

The SysOM component is the core management component of the operating system. All console features depend on this component. The persistent SysOM component consumes the following resources:

Memory: Approximately 300 MiB on average, with a maximum of 500 MiB.
CPU: An average of 5% on a single-core CPU.

Can anomaly reports be automatically generated when an anomaly is detected?

Yes, they can. The System Overview feature generates real-time anomaly events. You can retrieve these events by calling the ListAbnormalyEvents - Get anomaly event details API operation. Automatic push notifications for anomaly events will be available in a future release.

Do I need to upgrade component versions to use all console features?

No, you do not.

Is the Operating System Console only for Alibaba Cloud Linux images?

This feature is not exclusive to Alibaba Cloud Linux images. For a full list of supported images, see Use the operating system console.

Is onboarding manual or automatic?

Onboarding applies to clusters and nodes. When you onboard a cluster, its nodes are automatically onboarded by default.

What should I do if my application experiences high latency when accessing basic services?

You can use the process call graph generated by the Process Hotspot Tracking feature to identify performance bottlenecks and hot spot issues in your application.

What should I do if my application has an out-of-memory (OOM) error or my ECS instance is unresponsive?

You can use the OOM Diagnosis feature to diagnose the cause of the OOM error in the operating system.

Can the Operating System Console help locate the cause of issues like high CPU, high memory, or full I/O utilization?

Yes, it can. You can select the appropriate diagnostic item for the specific issue to analyze and resolve it.

CentOS 7 is reaching its end-of-life (EOL), but migrating to Alibaba Cloud Linux is difficult. What should I do?

The Operating System Console provides features such as monitoring, alerting, and subscriptions to reduce the threats associated with the CentOS 7 end-of-life. However, for a long-term solution, replace or upgrade your operating system.

How can I effectively distinguish between test and production environments to avoid disrupting normal business operations?

You can use the grayscale deployment feature in the Operating System Console. You can batch install components for ACK clusters and use various grayscale deployment policies, such as those based on values, percentages, or ACK node tags, to distinguish between environments. For more information, see Grayscale deployment of components in an ACK cluster.
