How Exo Ensures Critical Alerts Get Through At Night
- =Reduce noise and alert fatigue
- =Escalations and persistent alerting
- =Increase transparency
- =Connect monitoring to operators that need to wake up at night
- =Consolidate alerting across multiple platforms

Challenge
exo is a public transportation provider in Montreal, Quebec that needs to maintain service availability around the clock. They needed a better way of connecting their monitoring environment with their operators, particularly at night:
- Monitoring (SCOM) generated a single alert with no automated escalation
- Critical alerts were easily missed if the operator didn’t hear the single email ding at night
- Alert fatigue made it difficult to separate critical incidents from routine notifications
- Managers lacked visibility into whether incidents had been acknowledged or resolved
exo supports business-critical applications that require 24/7 monitoring. The challenge was ensuring critical alerts reached the right person overnight without waking operators for routine issues or false alarms.
Solution
After evaluating several alternatives – including custom scripting solutions – exo selected SIGNL4 as its centralized alerting and escalation platform, connecting monitoring systems directly with on-call operators:
- Centralizing alerts: Consolidated alerts from SCOM, SolarWinds, Azure, and other event sources into a single alerting platform.
- Standardized communication: Established a consistent alerting process across all monitoring and event management systems.
- Personalization for after-hours: Operators have personalized their notification channels with the option that works best for waking them up at night
- Reducing Noise: Working with event sources, that do not have a proper filtering mechanism, exo can use SIGNL4’s capabilities to separate the critical from the non-critical
Benefits
The benefits were immediate. Operators – and even their families -quickly embraced the new approach because they knew overnight notifications would only occur when action was truly required.
- Targeted routing and reduced alert fatigue: Operators know that when SIGNL4 calls, the alert is important and requires immediate attention.
- Peace of mind: If an operator doesn’t respond, automatic escalations trigger for reliable 24/7 alerting.
- Improved operational visibility: Complete visibility into alert acknowledgments, escalations, and resolution status.
- One central communication hub: Consolidation across multiple monitoring platforms and event sources.
exo is now exploring SIGNL4 Remote Actions, enabling operators to trigger remediation tasks directly from alerts and further reduce response times.
