SIGNL4 Integration with Netdata

Netdata is a real-time observability platform for infrastructure, containers, applications, and hardware. It provides per-second metrics, automated dashboards, AI/ML-based anomaly detection, alerting, and log management, and it scales to large environments without requiring all data to be centralized.

SIGNL4 enhances Netdata with reliable mobile alerting, including a mobile app, push notifications, SMS messages, voice calls, automated escalations, and on-call scheduling. SIGNL4 ensures that critical alerts reach the right people reliably – anytime, anywhere.
