With built-in duty scheduling, tracking, and automatic escalations, you ensure fast response times – even outside business hours.

Driving Impact in IT Operations and Monitoring with IT Alerting Software SIGNL4
Immediate incident response and escalation without complex IT Alerting tools
Of course, it is important that especially critical IT alerts are processed promptly. Even small problems can quickly lead to major failures. Channels such as email and dashboards are often the means of choice, as they come built into most monitoring tools. However, you need to be aware of the limits of these two methods and allow SIGNL4 to help your digital transformation:
- Location-independent attention-grabbing: Dashboards require constant attention and/or appropriate access, e.g. a PC/monitor. The employees’ freedom of movement is restricted. IT Alerting via smartphone, call and SMS by SIGNL4 ensures greater flexibility and mobility.
- Email has several disadvantages: Important alerts have the same relevance in a mailbox as an Amazon delivery notification. Tracking (alert acknowledged, resolved or not) is difficult to cumbersome. And assigned responsibility for an incident (takeover by a colleague) is also difficult. SIGNL4 provides a remedy here. Alerts can be acknowledge for clear ownership. Signaling can be adjusted to the severity and other parameters. The status of an alert can be viewed directly, updates are provided in real time.
Key Features to Avoid Temporary Alerts and Alert Fatigue in IT Alerting
- Alerts can be filtered. Distribution rules in SIGNL4 include a powerful filter system allowing to parse content and parameters of incoming data and events (messages from monitoring systems). If the required data are not included, an event is not processed and an alert is not transmitted or triggered.
- SIGNL4 allows you to set up multiple alert categories, each with tailored signaling and visualization options, including clear indicators of incident severity.
- Distribution rules can also be used to send alerts exclusively to specific teams or team members according to their responsibilities and capabilities.
- Particularly in network environments, there are often brief equipment downtimes or sensor signals that auto-resolve after a few seconds. Such alerts can cause a lot of work and require unnessary attention, because it takes a lot of effort to track the validity of such alerts.
- SIGNL4 can also process a monitoring alert in a third party system via 2-way connectors and its REST API. This means that when an alarm reset occurs in the monitoring system, the alarm is also set to closed in SIGNL4 and alert notifications are stopped. At the same time, the alert remains visible in the log for later analytics. It only takes 5 minutes to leverage integration capabilities provided by SIGNL4 and boost your IT Alerting.
