The O&M Dashboard page in Operation Center displays the overall O&M information, including the results of O&M stability assessment, key O&M metrics, usage of scheduling resources, and status information about auto triggered tasks. This page also displays information about synchronization tasks in Data Integration. This helps you quickly understand the overall information about tasks in your workspace, identify and handle exceptions at the earliest opportunity, and improve O&M efficiency.
Usage notes
The O&M Dashboard page allows you to view the overall O&M information about workspaces and the O&M information about synchronization tasks in Data Integration of workspaces from the following perspectives:
Specified workspace: You can view O&M information about a specified workspace, including the overall O&M information about the workspace and the O&M information about synchronization tasks in Data Integration of the workspace.
All workspaces: You can view the overall O&M information about all workspaces within your current account. From this perspective, you cannot view the O&M information about synchronization tasks in Data Integration.
Limits
In a workspace in standard mode, you cannot use the O&M Dashboard module in Operation Center in the development environment. In a workspace in standard mode, you can switch between the production environment and development environment in the top navigation bar in Operation Center.
The Workbench Overview tab displays only the statistics on O&M information about auto triggered tasks and auto triggered instances.

Log on to the DataWorks console. In the top navigation bar, select the desired region. In the left-side navigation pane, choose . On the page that appears, select the desired workspace from the drop-down list and click Go to Operation Center.
View the statistics on the Workbench Overview tab
The Workbench Overview tab displays the O&M information about your workspace in different dimensions, including overall O&M stability, O&M issues, running details of auto triggered tasks and auto triggered instances, usage of resources in resource groups, ranking of instances in different states, and ranking of instances with errors.
View information in the O&M Stability Assessment section
In the O&M Stability Assessment section, the O&M stability of your workspace is assessed based on the overall running details of tasks in your workspace. The health status for O&M stability can be excellent, good, medium, or poor. If high-risk or low-risk items are displayed, the health status of the workspace is poor. You must handle the risky items and optimize the performance of the workspace at the earliest opportunity. You can select All Project in the top navigation bar to view the following information about all workspaces: stability assessment result, number of auto triggered instances, and completion rate of auto triggered instances.
View information in the Focus On section
The Focus On section displays the O&M exceptions from the workspace and individual perspectives based on exception statistics of intelligent baselines and auto triggered tasks. You can view the overall information in your workspace or view only the information about tasks of which you are the owner to identify and handle exceptions at the earliest opportunity and ensure that your business is not affected. 
The following table describes common exception types.
Exception type | Description | References |
Baseline in Overtime | Counts the number of baseline instances that are in the overtime state on the current day. If a task in a baseline is still running when the committed completion time of the baseline arrives, an instance that is generated for the task enters the overtime state. | |
Baseline in Alert | Counts the number of baseline instances that are in the alert state on the current day. You can specify an alert margin threshold to ensure that important data is generated as expected in scenarios in which dependencies between tasks in the baseline are complex. If the alert margin threshold is exceeded, tasks may fail to finish running as expected and exceptions may occur. | |
Error-related Events | Counts the number of error-related events that are generated on the current day. An error-related event is generated if a task in a baseline fails. In this case, the running of descendant tasks of the task may be blocked. You must handle the error at the earliest opportunity to prevent the task from affecting the running of its descendant tasks. | |
Slowdown Events | Counts the number of slowdown events that are generated on the current day. A slowdown event is generated if the running duration of a task in a baseline is significantly longer than the average running duration of the task in the historical periods of time. | |
Isolated Nodes | Counts the number of isolated tasks on the current day. If an auto triggered task does not have an ancestor task, the auto triggered task becomes an isolated task. In this case, the task cannot be automatically scheduled to run. | |
Frozen Nodes | Counts the number of auto triggered tasks that are frozen on the current day. If an auto triggered task is frozen, instances that are generated for the task are also frozen. Frozen instances are not automatically scheduled, and the descendant instances of the frozen instances are blocked from running. | |
Expired Nodes | Counts the number of auto triggered tasks for which the effective period of scheduling expires. The system generates instances for an auto triggered task and runs the instances within the effective period of scheduling of the task. If the effective period of scheduling expires, the system does not generate or schedule auto triggered instances of the task. | None |
Modified Nodes | Counts the number of auto triggered tasks whose configurations are modified on the current day.
Note If you select Mine in the upper-right corner of the Focus On section, only the number of modified tasks of which you are the owner is counted. | None |

View information in the Resource Usage in Resource Group for Scheduling section
This section displays the resource usage of a resource group for scheduling and the trend in the number of instances that are run on the resource group over a specific period of time. The Resource Usage line shows the percentage of the resources used by the instances that are run on the specified resource group. If the resource usage of a resource group exceeds 80%, we recommend that you scale out the resource group to prevent insufficient resources from affecting the running of tasks.
This section displays statistics for a maximum of seven days.
The Resource Usage and Instances metrics apply to resource groups. For example, if multiple workspaces share the exclusive resource group for scheduling that you use, this section displays the resource usage and the trend in the number of instances that are run on the resource group in all the workspaces.
