Mobile workers are not able to sit in front of a Checkmk dashboard and actively monitor problems. SIGNL4 enables Checkmk to notify the mobile teams in the field or on call in real-time. This speeds up their response significantly and frees resources in the operations.

 How it Works

Checkmk sends detailed problem information by using a webhook or email to SIGNL4, informing the on-call team or technician. The Checkmk connector in SIGNL4 allows status updates to be sent directly from the SIGNL4 mobile app, like acknowledging an alert. This ensures both SIGNL4 and Checkmk dashboard users have real-time information on problem resolution status. If Checkmk recognizes a solution (UP), it automatically updates SIGNL4 and closes the alarm.

Tips & Tricks


Alert Optimization

SIGNL4 can further increase the visibility of alerts through its Signals and Services categories. Augmenting the color and icon of alerts will provide more relevant information at a glance without having to open the alert. You can also augment ticket alerts with maps or change the subject or message to a more comprehensible content.

Alert categories in SIGNL4 also allow to group ticket alerts and even to route those ticket notifications to your staff based on skills or other criteria. Screenshots show how to override text, colors and titles are triggered by keywords set within the mobile app.
