    • getGroupStatus

      public org.apache.nifi.controller.status.ProcessGroupStatus getGroupStatus(String groupId)
      Returns the status of all components in the specified group. This request is not in the context of a user so the results will be unfiltered.
      Specified by:
      getGroupStatus in interface EventAccess
      Parameters:
      groupId - group id
      Returns:
      the component status

    • getGroupStatus

      public org.apache.nifi.controller.status.ProcessGroupStatus getGroupStatus(String groupId, RepositoryStatusReport statusReport)
      Returns the status for the components in the specified group with the specified report. This request is not in the context of a user so the results will be unfiltered.
      Parameters:
      groupId - group id
      statusReport - report
      Returns:
      the component status

    • generateRepositoryStatusReport

      protected RepositoryStatusReport generateRepositoryStatusReport()

    • getGroupStatus

      org.apache.nifi.controller.status.ProcessGroupStatus getGroupStatus(ProcessGroup group, RepositoryStatusReport statusReport, Predicate<Authorizable> checkAuthorization, int recursiveStatusDepth, int currentDepth, boolean includeConnectionDetails)
      Returns the status for the components in the specified group with the specified report. The results will be filtered by executing the specified predicate.
      Parameters:
      group - group id
      statusReport - report
      checkAuthorization - is authorized check
      recursiveStatusDepth - the number of levels deep we should recurse and still include the the processors' statuses, the groups' statuses, etc. in the returned ProcessGroupStatus
      currentDepth - the current number of levels deep that we have recursed
      includeConnectionDetails - whether or not to include the details of the connections that may be expensive to calculate and/or require locks be obtained
      Returns:
      the component status
