Monitoring an Instance

Performing Job Instance Operations

1. Log in to the DataArts Studio console. Locate an instance and click Access. On the displayed page, locate a workspace and click DataArts Factory.
   Figure 1 DataArts Factory
   
2. In the navigation tree on the left of the DataArts Factory page, choose Monitoring > Monitor Instance
3. You can stop, rerun, continue to run, or forcibly run jobs in batches. For details, see Table 1.

   When multiple instances are rerun in batches, the sequence is as follows:

   • If a job does not depend on the previous schedule cycle, multiple instances run concurrently.
   • If jobs are dependent on their own, multiple instances are executed in serial mode. The instance that first finishes running in the previous schedule cycle is the first one to rerun.
4. Table 1 describes the operations that can be performed on the instance.

   Table 1 Instance monitoring operations

   Operation	Description
   Searching for a job based on the job name or creator	If you select Exact search, exact search by job name is supported. If you do not select Exact search, fuzzy search by job name is supported.
   Filtering jobs by CDM job or node type	-
   Stop	Stop an instance that is in the Waiting, Running, or Abnormal state.
   Rerun	Rerun a subjob instance that is in the Succeed or Canceled state. For details, see Rerunning Job Instances.
   View Waiting Job Instance	When the instance is in the waiting state, you can view the waiting job instance.
   More > Continue	If an instance is in the Abnormal state, you can click Continue to begin running the subsequent nodes in the instance. NOTE: This operation can be performed only when Failure Policy is set to Suspend the current job execution plan. To view the current failure policy, click a node and then click Advanced Settings on the Node Properties page.
   More > Succeed	Forcibly change the status of an instance from Abnormal, Canceled, or Failed to Succeed.
   More > View	Go to the job development page and view job information.

5. Click in front of an instance. The running records of all nodes in the instance are displayed.
6. Table 2 describes the actions that can be performed on the node.

   Table 2 Operations (node)

   Operation	Description
   View Log	View the log information of a node.
   More > Manual Retry	To run a node again after it fails, click Retry. NOTE: This operation can be performed only when Failure Policy is set to Suspend the current job execution plan. To view the current failure policy, click a node and then click Advanced Settings on the Node Properties page.
   More > Succeed	Change the status of a node from Failed to Succeed. NOTE: This operation can be performed only when Failure Policy is set to Suspend the current job execution plan. To view the current failure policy, click a node and then click Advanced Settings on the Node Properties page.
   More > Skip	To skip a node that is to be run or that has been paused, click Skip.
   More > Pause	To pause a node that is to be run, click Pause. Nodes queued after the paused node will be blocked.
   More > Resume	To resume a paused node, click Resume.

Rerunning Job Instances

You can rerun a job instance that is successfully executed or fails to be executed by setting its rerun position.

1. Log in to the DataArts Studio console. Locate an instance and click Access. On the displayed page, locate a workspace and click DataArts Factory.
   Figure 2 DataArts Factory
   
2. In the navigation tree on the left of the DataArts Factory page, choose Monitoring > Monitor Instance
3. In the Operation column of a job, click Rerun to rerun the job instance. Alternatively, click the check box on the left of a job, and then click the Rerun button to rerun the job instance.

   Table 3 Parameters for rerunning a job

   Parameter	Description
   Rerun Type	Type of the instance that you want to rerun. Rerun selected instance Rerun instances of selected job and its upstream and downstream jobs
   Start Time	Time range in which instances have been run
   List of Rerun Job Instances	Upstream and downstream jobs to rerun. You can select multiple jobs at a time.
   Rerun From	Start position from which the job instance reruns. Error node: When a job instance fails to be run, it reruns since the error node of the job instance. The first node: When a job instance fails to be run, it reruns since the first node of the job instance. Specified node: When a job instance fails to run, it reruns since the node specified in the job instance. This option is available only if Rerun Type is set to Rerun selected instance. NOTE: A job instance reruns from its first node if either of the following cases occurs: The quantity or name of a node in the job changes. The job instance has been successfully run.
   Concurrent Instances	Number of job instances that can be concurrently processed.
