Note that all times used in the Discovery Scheduling feature use the UTC time zone, including the calendar views and the time of day for scheduled scans.
The Discovery Scheduling feature is not available for legacy IT HealthCheck subscriptions.
Regularly doing a discovery on an environment captures any changes (new servers or VMs stood up or spun down).
The Discovery Scheduling feature becomes available after the initial scan of the environment has been requested. Following the initial scan, the "Schedule Rescans" button will appear next to the "Request Rescan" button on the RN150 Dashboard page.
Selecting the "Schedule Rescans" button will open the Discovery Scheduler page. This page provides a calendar view of the current month showing the currently scheduled Discoveries. You can navigate forwards and backwards through months of the year using the "<" and ">" buttons on the top right of the calendar view. The "Today" button will navigate back to the current month with the current day highlighted.
Selecting the "+ Add" button will open a dialog for scheduling a new Discovery scan. You can modify any existing scheduled Discovery scan by clicking on an entry shown in the calendar.
When the appliance is in discovery mode it IS NOT collecting performance data. To maintain appropriate balance between performance collection and discovery we recommend scheduling discoveries no more frequent than once every couple of days. Often a weekly schedule may be optimal.
A scheduled scan acts exactly the same as if the "Request Rescan" button had been selected from the RN150 Appliance Dashboard. The scan is requested at the time it was scheduled, and will begin running up to several minutes later. An email notification will be sent when the scan starts, and when the scan has completed and updated Assets information is available in the Portal or FlexDeploy Appliance. Scheduled scans always use the behavior as if the "View Inventory Changes" feature had been selected, which will refresh the data for Assets that have previously been inventoried as well as discovering any new devices. Note that the subnet scope used during a scheduled scan reflects the currently selected subnet entries in the RN150 Subnets page at the the scan is initiated.
If the RN150 Appliance does not have connectivity with the RISC Networks NOC (referred to as being "offline") at the time the scan is scheduled, the scan will not be initiated and the RN150 Appliance will not attempt to run any scheduled scans that were missed when connectivity is resumed.
Adding A New Scheduled Discovery Scan
Select the "+ Add" button at the top right of the calendar to open the "Schedule A Discovery" dialog for adding a new Discovery scan to the schedule.
Selecting the "Run Date" input field will open a calendar where the day can be selected. A Discovery cannot be scheduled in the past, so days prior to the current day, and months prior to the current month, cannot be selected. Click on the desired day to request the scan.
Next, select the time of day to request the scan, in the UTC time zone. The minutes field shows a range of times in 15 minute increments. A range is shown to indicate the asynchronous nature of scan requests. The scan will be requested at the beginning of the time range (for instance, if the "30-45" minute range is selected, the scan will be requested at the 30th minute of the hour, but the scan will actually begin running up to several minutes later.
To schedule a single Discovery scan, leave the "Repeat Every" field at the default value of 0. If you would like to schedule a routine, recurring scan, the "Repeat Every" value should be set to the number of days between requests. For instance, to request a weekly rescan on the same day of the week, set the "Repeat Every" value to 7. The selected hour and minute of the day will be used for each scan request initiated in the series.
Select "Add" to complete the configuration and add the new scan(s) to the schedule. The new scans will now appear in the calendar view on the page. The "Cancel" button can be selected at any time before selecting "Add" to quit configuration, which will not add the scan(s) to the schedule.
Updating An Existing Scheduled Discovery Scan
From the main calendar view, click on the calendar entry that you would like to change. This will open the "Edit A Scheduled Discovery" dialog. From this dialog, any parameter of the scheduled scan can be manipulated, including the day, time of day, and recurrence. To finalize any changes, select "Update". If you would like to permanently remove the scan from the schedule, select "Delete". Selecting "Cancel" will close the dialog without making any changes to the schedule.
When editing a scheduled scan that is part of a recurring series (the "Repeat Every" value is greater than zero), note that any changes made to a scheduled scan in the series operates on the series as a whole. This means that changing the time of day on any element of the series will change the time of day for all subsequent scans, changing the "Repeat Every" recurrence value will change the interval between all scans in the series (beginning from the original scan in the series), and selecting "Delete" will remove all entries part of that series
Note that scheduled scans that have already occurred cannot be modified.
