        2. Base URLOptional: Based on the selected .js script file, this field is populated with the base URL on which the monitor is to be run. Optionally, you can also specify the base URL in this field.
        3. Script Parameters: If script parameters are defined in the contents of the script file, then they are displayed in the Script Parameter fields and you can choose to replace the parameter values. Note that the parameter value is not displayed if the Value is secret option is used when creating or uploading the script.
        4. Options: Optionally, select the following check box:
           • Override DNS: Select this option to specify the IP address to which the target's domain name will resolve, instead of using the standard DNS resolution.

   Click Next.

6. On the Run Settings page:
   1. Vantage Points: Select the vantage points on which you want the monitor to run. If you've set up a Dedicated Vantage Point, then it is also listed in the drop-down list and can be selected. For information on Dedicated Vantage Points, see Use Dedicated Vantage Points.
   2. Select one of the following radio buttons to determine the frequency of monitor runs:
      • Interval: Select this radio button to determine the interval of time between each monitor run.
      • Run Once: Select this radio button if you want the monitor to run only once. If the Run Once radio button is selected, the Scheduling Policy drop-down list and the Interval Between Runs (minutes) field are disabled.
   3. Scheduling Policy: Select one of the following options to stagger the monitor runs on the selected vantage points:
      • All: Select this option to run the monitor simultaneously on all selected vantage points.
      • Round Robin: Select this option to schedule the monitor run sequentially on each vantage point. This functionality works in tandem with the value specified in the Interval Between Runs (minutes) field. For example, if 10 minutes is specified in the Interval Between Runs (minutes) field and the monitor is to run on five vantage points, then the monitor will run on the vantage points sequentially with an interval of ten minutes between each run. The total duration of the monitor runs on all vantage points will then be 50 minutes, after which the sequential monitor run will begin again.
      • Batched Round Robin: Select this option to schedule the monitor run sequentially on batches of vantage points. This functionality works in tandem with the values specified in the Interval Between Runs (minutes) and Sub-interval Between Runs (minutes) fields. In this scenario, monitors are scheduled to run on batches of vantage points and the interval between each run is specified in the Sub-interval Between Runs (minutes) field. The value in the Interval Between Runs (minutes) field denotes the total time taken for the monitor run on all batches.

        The number of vantage points in each batch is automatically calculated based on the number of selected vantage points and the values specified in the Interval Between Runs (minutes) and Sub-interval Between Runs (minutes) fields. For example, if there are 7 vantage points, Interval Between Runs (minutes) = 10 minutes, and Sub-interval Between Runs (minutes) = 5 minutes, then two batches are created. The first batch of vantage points will have four vantage points and the second batch will have three.

        
        
        
        
        
   4. Interval Between Runs (minutes): Specify the number of minutes between monitor runs. The default interval duration is 10 minutes. For the REST monitor type, you can specify one minute as the minimum duration of the interval between monitor runs, and for the other monitor types, you can specify five minutes as the minimum duration.

      Note that if the Batched Round Robin option is selected in the Scheduling Policy drop-down list, then the value selected in the Interval Between Runs (minutes) field denotes the total time taken for the monitor run on all batches.

   5. Sub-interval Between Runs (minutes): Specify the number of minutes between monitor runs on batches of vantage points. Note that this field is only displayed if the Batched Round Robin option is selected in the Scheduling Policy drop-down list.
   6. Timeout: Specify the timeout value. This denotes the maximum runtime allowed and if the monitor runtime does not complete within this time, it will be stopped and marked as a failure. Note that the Interval Between Runs value must be about three times more than the Timeout value.
   7. Enable Retry: Select this check box to retry execution in case of failure. Note that this check box is selected by default.
   8. Enable Network Collection: Select this check box to enable data collection from the network and monitor network performance. Note that for a Scripted REST monitor, this check box is only displayed if the Base URL is specified on the Monitor Definition page:

      On selecting the Enable Network Collection check box, the following options are displayed:

      • Protocol: Select a network protocol.
      • Probe Mode: Select a probe mode for the TCP network protocol. Note that the Probe Mode option is only available for the TCP network protocol.
      • Probe Per Hop: Specify the number of probe packets sent per hop.

   Click Next.

7. On the Tags (Optional) page, you can choose to use the Tagging metadata system to organize and track the monitors, and click Next.
   If tags are added to the monitor, you can filter and view monitors on the Monitors page using Tag Filters on the left pane.

   For information on Tagging, see Tagging Overview.

8. On the Summary page, review the summary of the monitor, and click Create.
