Manage defined alerts
Devo users with the necessary administrative permissions can perform the following tasks with existing alerts (see Configuring alerts to see the permissions needed):
All of these tasks are carried out in the Available Alerts tab of the Administration → Alert Configuration area.
You can only edit the definition of the alerts created by users in your domain, which are in the My Alerts category. The pre-installed alerts provided by Devo cannot be edited.
Filter alerts
Since the number of existing alerts in a domain is potentially high, the process of filtering alerts provides a quick way of finding them and is therefore an instrumental step to perform prior to any other task.
There are three different methods to filter alerts: a global one that affects all the structure (the top filter) and the other two that affect only the alerts list.
The top filter is somehow similar to the Data Search finder in the sense that the lists are hierarchical. The box on the left represents the categories, the box on the right represents the subcategories and the list below shows the alerts that correspond to the category-subcategory combination selected.
- Selecting a category in the box on the left will cause a cascade filtering to show only the category, its subcategories and the alerts inside those subcategories.
- Selecting a subcategory will cause further cascading to show only the alerts inside that subcategory. If it is selected without selecting a category before, the filtering is performed in both directions of the hierarchy to show only the parent category and the child alerts.
Clicking All Categories/Subcategories will reset the filters up to that level. This means All Categories will show everything again while All Subcategories will show everything inside the selected category. These options will be disabled until a selection is made on the corresponding box.
As alerts are created and deleted over time, it's possible that a subcategory that was created in the past no longer contains any alerts. When this happens, Devo lets you know by displaying a Delete button when you hover over the subcategory in the filter list.
It is also possible to filter directly on the Alerts list. To do this, you have two different options:
- Use the general filter: write the desired string and click on Filter to show only those alerts that contain such a string in any of their fields (category, subcategory, name, owner, etc.). Click Clear Filter to remove the filtering criteria.
- Use the column filter: click on the desired column filter and write the desired string. The alerts will be filtered as you type, showing only those that contain such a string in that specific field. To remove the filtering criteria, just delete the string.
Be aware that these methods work independently. This means their use in combination does not imply substitution or overruling of one criterion over another but an aggregation for a more concise approach. Similarly, each option to reset the filtering criteria only reaches the scope of its corresponding method, in other words, they can reset only the filters they are capable of applying (All Categories-Categories, All Subcategories-Subcategories, Clear Filter-Alerts).
Edit the query and basic information of an alert
Note that if you want to edit the query that feeds the alert, you should do that prior to making any modifications to the alert's basic information, as we indicate in this procedure.
- Inside Administration → Alert Configuration → Available Alerts, click My Alerts in the Categories filter box to list only your domain's custom alerts. Find the alert you want to edit (you can use the filters explained in the section above).
- Hover over the alert's row in the list, then click the ellipsis menu and select Edit. The Edit Alert Definition window appears.
- (Optional) If you want to edit the actual query, click Edit. The query opens in the search window where you can make the necessary modifications. When you are finished editing the query, select Additional Tools → Set this Query in Alert to save the query definition in the alert. This returns you to the Edit Alert Definition window.
- To modify the alert's Summary, Description, Priority, or trigger definition, edit the field values directly.
- When you're finished, click Update to save your changes.
Activate or deactivate an alert
If you want to stop an alert temporarily so that you can start it again in the future, you can deactivate it. You need to locate it inside Administration → Alert Configuration → Available Alerts (you can use the filters explained in the section above) and then simply use the ON/OFF slider in its row to activate or deactivate it.
Delete an alert
Delete an alert when you have determined that it is no longer going to be useful to your domain users. Deleting an alert has no impact on the query whose data has been feeding the alert. It simply removes the alert.
- Inside Administration → Alert Configuration → Available Alerts, click My Alerts in the Categories filter box to list only your domain's custom alerts. Find the alert you want to edit (you can use the filters explained in the section above).
- Hover over the alert's row in the list, then click the ellipsis menu and select Delete. A confirmation window appears. Click Yes to delete the alert.
Remember that you can deactivate an alert if you think it might be useful in the future and you only need to stop it temporarily.
