Alarms are specific to a site and the data it is providing. To specify the conditions for an alarm, you must select the site and dataset to be monitored.
1. Expand the Sites panel by clicking the Sites tab.
This panel contains the fields used to select the source data for the alarm. The Select a site field is populated with all sites in the instance.
2. Click in the Select a site field to expand the field.
The list of sites can be filtered by specifying textual search criteria in the Search field at the top of the list. Only sites that match the text specified will be included in the list. A drop-down list beside the Search field can be used to filter the list even further by specifying the property in which to search for the matching text. When an option is selected, only sites with text in the selected property (tenant, tag, etc.) will be available.
3. Select a site from the list.
All ingested datasets and computed datasets available for the selected site will be displayed in a drop-down list. Additional sites can be selected to display more datasets if needed.
4. [Optional] Click in the site field again and select additional sites as needed.
5. Expand the datasets drop-down lists to view the available datasets.
The Properties button (...) beside each dataset in the list displays a dialog box containing information about the dataset.
6. Select the dataset that you want to set a condition for and drag it to the top of the Start Condition list.
The dataset is only shown in the Start condition field because, by default, the End condition is the opposite of the Start condition and does not require the user to specify the criteria manually. If a custom end condition is required, the dataset can also be added to the End condition field and criteria specified.
7. Select a conditional operator by clicking the drop-down arrow inside the Start condition field.
8. Click the Val field and type a value for the Start Condition.
9. Select a unit of measure for the value.
The duration controls can be used to specify a length of time that the condition must be detected during ingestion in order for the conditions of the alarm to be met. For Rainfall data, the Duration option is renamed Within and will detect an event when the rain accumulation amount exceeds the limit within the specified time period.
10. [Optional] Click the check box to enable the duration controls.
11. [Optional] Specify a value and unit for the duration.
If a different End condition is needed, a dataset must be added to the End condition field and the settings defined manually.
12. [Optional] Drag the relevant dataset to the End condition field.
13. [Optional] Select an operator and type a value for the End Condition.
The first condition is now complete.
14. Drag another dataset into the Start condition list to add a second condition. This can be either above or below the first condition.
When a second dataset is added, a boolean operator must be selected to identify the relationship between the first and second conditions.
Boolean operators include.
• And: Both conditions must be met to trigger an alarm. When either condition is no longer met the alarm is deactivated.
• Or: Either condition must be met to trigger an alarm. When both conditions are no longer met the alarm is deactivated.
In the following example, an alarm will be triggered when both the Velocity goes above 5 feet per second and Level goes above 10 inches and remains that way for 1 hour. The alarm condition ends when either value falls below their End condition value because, when using the And operator, both start conditions must be maintained for the alarm to continue.
15. Select a boolean operator for both the Start and End conditions.
16. Select a conditional operator for the second dataset.
17. Type the value for the second condition.
18. Select a unit of measure for the second condition.
19. [Optional] Click the check box to enable the duration controls.
20. [Optional] Specify a value and unit for the duration.
The conditions are now complete.
21. Click the Create alarm settings button 
.
You are returned to the Settings page and the new alarm is available in the list.
