Configuring one-time job settings for proactive problem management

As a problem coordinator, you can configure and run one-time clustering jobs for proactive problem management. You can create a maximum of three jobs.
When you set up a one-time clustering job, the algorithm runs once to cluster incidents based on the selected criteria.
By default, a maximum of 200000 incidents are considered while creating a one-time Proactive problem management job. However, you can increase the limit by customization.

To create a one-time job

  1. On the Proactive problem management settings page, click Create one-time job
  2. In the General section, enter a job name. 
  3. Select the language for the incident text processing. Even though your incident text contains mixed language, pre-processing is done on the basis of the selected language.
  4. In the Data Set section select the fields on which you want to create clusters. 

    To also view the required system fields, select the Show system fields check box. The system fields cannot be removed. Except for Submitter, all other system fields cannot be removed. Some fields may be hidden from the data set by your admin to comply with privacy regulations.

  5. You can apply filters on the fields to further refine your data set. 

    1. Click the required filter category and select one of the following options:

      OptionDescription
      Equals to

      Select this option to include values in the filter.

      Not equals to

      Select this option to exclude values from the filter.

    2. Search and select the field value that you want to include or exclude.
    3. Click Apply filters.

      • Searching for a string without a wildcard (%) is not supported in a filter that has a text field. We recommend using a wildcard (%) for a search in such filters.
      • The Equals to and Not equals to options only appear in fields with a character menu, such as Service CI.


  6. In the Data range section, specify the date range that the job should use to search incident data. The Data range date field is the date field that is used to search for incidents within the defined data range.

    Best practice

    Define your date range based on the problem management process and review cycles for problem identification in your organization.

    The recommended date range is the previous 1-4 weeks of data. 



  7. In the Create clusters section, specify the parameters by which the data is to be grouped. 
    1. For the first level of grouping, select from one of the data fields. If you select Machine learning, you cannot select the second level grouping. 
    2. For the second level of groupings, you can select Machine learning or another set of data fields (excluding the data field already selected in level 1 grouping). 
    3. If you have selected Machine learning, you can specify the text fields to be clustered, but Summary is the default text field that is used. 

      Important

      If you have not selected Machine learning in any of the Group by fields, then a clustering job is not run and incidents are grouped by the selected fields.


  8. In the Advanced machine learning section, the Let the system set the number of clusters check box is selected by default.

    Best practice

    When selecting the number of clusters, we recommend selecting the Let the system find no. of clusters check box rather than setting the number of clusters yourself. The system automatically selects an optimal number of clusters. However, when you know the number of clusters from prior execution runs or domain knowledge, you can specify a value to improve the response time. We recommend setting 20-30 clusters for optimal incident monitoring.

  9. You can upload custom stop words in the form of .txt file where each stop word is defined on a new line. Stop words are commonly used words that are ignored when the text is processed.
    Every time you upload a new file containing the updated stop words, it overrides the old file. 

    BMC Helix ITSM Insights has a built-in library of stop words for every supported language. The algorithm refers to the library and your preferred stop words while processing incident information.

    Important

    While generating cluster labels in the dashboard from the relevant incidents, the algorithm compares the incident description words with the stop word library. Therefore, the cluster labels do not contain words mentioned in the stop word library.

    The following table describes the usage of in stop words:

    Incident summaryStop wordDescription
    ITSMInsights is running low on memoryITSM%Removes the stop word ITSM and the characters following it.
    In this case, ITSMInsights is removed from the resulting cluster label.
    ITSMInsights is running low on memory%Ins%Removes the stop word Ins and the characters preceding and following it.
    In this case, ITSMInsights is removed from the resulting cluster label.
    ITSMInsights is running low on memory%InsightsRemoves the stop word Insights and the characters preceding it.
    In this case, ITSMInsights is removed from the resulting cluster label.

    Important

    Stop words are case-sensitive. We recommend matching the case of your stop word with that of the word in the description that you want to remove.

  10. Click Run now.

The job configuration is saved. A job might take several minutes to complete, depending on the incident data to be processed. Refresh the jobs table to check if the job is completed. 

When the job run is completed, the jobs table displays job status in the Jobs table. If the job run was not successful, the Job message column displays the reason why the job failed. Once the job is successfully run, you can select it from the Jobs list in the dashboard to view the clusters.

Important

  • Depending on number of records or incidents and the kind of incident data, the number of clusters on the dashboard could be less than the number you have specified.
  • Running a job multiple times with the same parameters may generate a different number of clusters. You may notice a slight difference in the number of clusters generated under the following conditions:
    • When you use Group by fields and let the system generate the ideal number of clusters.
    • When you use Group by fields and provide a cluster value.
  • The algorithm groups incidents that have similar words in their description and avoids generating one-word cluster labels in the dashboard. Therefore, if an incident has a one-word description, the algorithm finds an existing cluster that has incidents with that word in its description sentence and adds the incident to that cluster.

To edit a recurrent job

To edit a recurrent job, click the edit icon in the Actions column. Make the necessary changes to the job.

The changes you have done will take effect in the next job run.

To delete a recurrent job

To delete a recurrent job, click the delete icon in the Actions column. When you delete a job, the job definitions, that is, the data fields and filters applied are also deleted. Also, all job runs associated with that job are deleted.
