ControlUp Scripts & Triggers Training & Support Archives

When configuring alerts in ControlUp based on device tags, a frequent question arises regarding whether selecting multiple device tags in the alert conditions operates as an OR or AND logic. It was clarified that in the current ControlUp alert configuration interface, when multiple device tags are selected, the alert triggers if the device has any one of the specified tags. This means the condition acts as a logical OR between the tags rather than an AND. The user interface presents these tag selections as checkboxes, limiting the direct ability to express compound AND logic (such as requiring both tags to be present simultaneously). There is no built-in switch or toggle to explicitly select AND versus OR behavior for device tag conditions. While the idea of combining tags using expressions like "tag1&&tag2" was discussed, this is not supported directly within the tag selection box, and typing such expressions does not function as a filter in the UI. However, a workaround approach involves leveraging multiple alert conditions, which are inherently ANDed together by ControlUp. For instance, instead of trying to combine two tags in one condition, you can create two separate conditions that must both be true, effectively achieving an AND between device tag criteria. Since tags are treated as string fields in the system, operators such as "contains" or "=" can be used in these conditions. Using "contains" is useful but may lead to partial matches, which requires careful tag naming conventions to avoid unintended matches (e.g., "reboot_device" matching both "reboot_device" and "no_reboot_device"). To address this, users have adapted by modifying their tagging strategies to use more distinctive and unambiguous tag names like "device_reboot_yes" and "device_reboot_no," which helps ensure that the use of "contains" or equality checks does not overlap between conflicting tags. Some users also explored adding exclusion conditions (e.g., conditions that exclude devices with certain tags), but these might not cover all scenarios adequately. The community suggested it would be valuable for ControlUp to enhance alert configuration with explicit AND/OR toggles or support for string operations like "starts with" to improve flexibility for tag-based alerting. Meanwhile, using multiple conditions combined with clear tag naming conventions is the recommended practical approach for achieving AND logic with device tags in alerts. For more detailed information on alert condition configuration and tag-based filtering, refer to the official ControlUp documentation at https://docs.controlup.com. This includes guidance on condition operators, tag management, and best practices for alert configurations.
