Addressing Alert Fatigue in Engineering for a More Resilient Future 🚨

Alert fatigue can inundate Engineering Teams with numerous context-lacking alerts, increasing costs and leading to underproductive teams.

Alerting serves as a convenient and efficient method for monitoring any application or service, eliminating the need for manually tracking essential metrics. In the presence of complex infrastructure, monitoring application health metrics as part of infrastructure-related alerts, including the general availability of services, to establish reliability around a resilient system becomes crucial. Additionally, proactive awareness of business-critical flow disruptions before customers report issues enables teams to investigate and apply corrective measures, minimizing the impact.

However, just as an excessive intake of sugar can lead to diabetes, an overload of alerts, coupled with the proliferation of systems, can result in "Alert Fatigue."
Alert fatigue can inundate Engineering Teams with numerous context-lacking alerts, increasing costs and leading to underproductive teams. Over time, operators may become desensitized, potentially missing important issues as they ignore or respond slowly to alerts. Unnecessary alerts can lead to burnout, adding a psychological burden to operators and engineers responsible for incident response.

This scenario stands in stark contrast to the original purpose of alerting.

Addressing alert fatigue involves several strategies: 💡

• Classification and Categorization: Classify and categorize alerts based on severity and context, grouping them by services.

• Actionable Alerts: Notify only alerts that require immediate action, with exceptions for specific cases like cloud service outages affecting multiple applications.

• Periodic Review: Regularly review existing alerts before adding new ones, adjusting thresholds, and muting alerts that haven't prompted action for an extended period.

• Segregation and Tunneling: Segment alerts based on infrastructure versus user flow, and adjust thresholds for alerts in different environments (Dev, Stage, Prod).

• Rely on SLO and SLI: Base alerts on Service Level Objectives (SLO) and Service Level Indicators (SLI).

• Self-Healing Alerts: Implement conditions for alerts to self-heal based on specific error occurrences with periodic intervals.
  
  As the saying goes, "A stitch in time saves nine 💊 ," but it's true that "Procrastination leads to more work."
