3.7.4 Suggestion of response actions appropriate to the system status

When a failure occurs in the system, our previous procedures required a series of processes to be carried out to address the failure, including reviewing the operational rules, identifying the business operations affected by the failure, checking and determining the system operation status, determining the actions that can be taken to properly address the failure, and implementing an appropriate action. This meant spending a considerable amount of time before the actual action can be undertaken to address the problem, which has been a huge burden for system operators.

The suggestion of response actions appropriate to the system status, which is based on the established operational rules and past operational records, offers a quick way to execute a suggested response action appropriate to the status of the system. It works like this: When one of the abnormalities being monitored for is detected, an operator requests suggestions from JP1/IM. In response to this, the Intelligent Integrated Management Base suggests several response actions that are appropriate to the current status of the system. All that the operator has to do to address the abnormality is select a suggestion and execute the corresponding response action.

This solution minimizes the efforts required to check the operational rules and to identify the business operations affected by the problem, and leads to a considerable reduction in the amount of time it takes to address failures in the system. It also reduces human errors and operational mistakes and enables smooth transition from system operation that relies heavily on human input to system operation management that is unaffected by the skills of the individuals using the system.

The following figure shows an overview of the process through which the Intelligent Integrated Management Base suggests response actions that are appropriate to the system status.

You can set the operational rules (suggestion activation criteria and response actions) to be used to suggest response actions appropriate to the system status by using the suggestion definition files. The use of linked products and the implementation of plug-ins enable advanced operation.

The following figure shows the relationship between operational rules and suggestion definition files.

The following table describes the types of information items that can be set as suggestion activation criteria. You can combine these information items by using an OR condition or AND condition.

Table 3‒11: Information items that can be set as suggestion activation criteria

JP1 event	Performance information (trend information)	Relation	Plug-in
Judgment of each attribute Correlations between multiple events	The number of time-series data items whose values have increased	Relations between jobs and infrastructures, or between jobs	Execution results of plug-ins, REST APIs, and commands

The following table describes the response actions that can be executed. Note that the information items referenced by suggestion activation criteria can be used as variables.

Table 3‒12: Response actions that can be executed

Change of the event status	Window display	Plug-ins, etc.
Changes can be made to the event status of JP1 events.	The Web window can be displayed to check the business impact and linked products.	Plug-ins, REST APIs, and commands can be executed.

You can define suggested response actions in suggestion definition files and apply them by executing the jddupdatesuggestion command. In the tree view in the Integrated Operation Viewer window, the icon is displayed beside the IM management nodes for which the Suggestion tab can be displayed.Furthermore, the following suggestion icons are displayed beside IM management nodes where a failure defined as Emergency/Alert/Critical, Error, or Warning has occurred:

• : Emergency/Alert/Critical

• : Error

• : Warning

When a user clicks an IM management node with one of these icons displayed beside it, the suggestion definitions mapped to the clicked IM management nodes are acquired, and a judgment is made as to whether the JP1 permission granted to the logged-in user matches the suggestion display criteria defined in the suggestion definitions. If the user's permission level matches the suggestion display criteria, a list of response actions shows up on the Suggestion tab.

When the user clicks the Suggestion button, the Intelligent Integrated Management Base automatically determines the system status, and activates and displays the suggestion definitions matching the suggestion activation criteria so that one of them can be executed as the response action.

After examining the details of the defined criteria and checking the specifics of the response actions that can be executed by the activated suggestions, the user determines which suggestion to execute. When the user clicks the Execute button, the response action is executed. This completes the response action necessary to address the failure.
