Component Monitoring¶
Components refer to the services that you deploy, including containers and common processes. For example, a workload on the Cloud Container Engine (CCE) is a component, and the Tomcat running on the VM is also a component.
The component list displays information such as type, CPU usage, and memory usage of each component. You can click a component name to learn more information about the component. AOM supports drill-down from a component to an instance, and then to a container. You can implement multi-dimensional monitoring.
Note
The ICAgent reports resource information every ten minutes. The resource status changes are described as follows:
If the ICAgent on a host does not report resource information for three consecutive times, the system determines that the resource has been deleted. Therefore, the host status is displayed as Deleted within 30 minutes after the ICAgent is uninstalled or the resource is deleted.
When the ICAgent on a host reports resource information for one time, the system determines that the resource is restored. The host status is displayed as Normal ten minutes after the ICAgent is reinstalled or the resource is restored.
In the navigation pane, choose Monitoring > Component Monitoring.
The component list displays information such as Component Name, Status, Application, and Deployment Mode.
Click
in the upper right corner and select Hide system component.
Perform the following operations as required:
Adding an alias
If a component name is complex and difficult to identify, you can add an alias for the component.
Click Add alias in the Operation column. The added alias can be modified but cannot be deleted.
Adding a tag
Tags are used to identify components. You can distinguish system components from non-system ones by using tags. By default, AOM adds the System Service tag to system components, including icagent, css-defender, nvidia-driver-installer, nvidia-gpu-device-plugin, kube-dns, org.tanukisoftware.wrapper.WrapperSimpleApp, evs-driver, obs-driver, sfs-driver, icwatchdog, and sh. You can click
in the upper right corner and select or deselect Hide system component. You can also customize tags to facilitate component management.Note
The Tags column of the component list is hidden by default. You can click
in the upper right corner and select or deselect Tags to show or hide them.
Set filter criteria to search for the desired component.
Note
Components cannot be searched by alias.
Click the component name to go to the Component Details page.
Click View Log next to the component name to go to the log search page and view the logs of the component. Logs of ServiceStage components cannot be viewed on the Component Details page.
On the Instance List tab page, view the instance details.
Note
Click an instance to monitor information such as resource usage and health status.
On the Host List tab page, view the host details.
On the Alarm Analysis tab page, view the alarm details.
Click the View Monitor Graphs tab to monitor the metrics of the component.
