Mobile alerting with tracking & escalation for Sematext



Sematext is a hybrid monitoring service capable of detecting and troubleshoot production & performance issues with logs, metrics, and real user monitoring. Performance monitors are easy to configure, and notifications channels are configured with just a few clicks.  SIGNL4 ensures that all on duty members receive, acknowledge and resolve critical alerts, all from their smartphones. With persistent notifications and escalation chains there will never be a critical alert that goes unattended. SIGNL4 also offers ad-hoc collaboration between team members for each alert, so Subject Matter Experts can be looped in to help resolve issues.
