4. Select Batch Policy.
   • Automatic: The selected hosts are automatically divided into multiple batches based on the preset rule.
   • Manual: You can manually create multiple batches and add instances to each batch as required.
   • No batch: All target instances are in the same batch.

   • You can set the execution success rate. When the number of failed hosts reaches the pre-set suspension threshold figure, the service ticket status becomes abnormal and the service ticket stops being executed.
   • The value range is from 0 to 100 and can be set to one decimal place.
