Alert fatigue, or alarm fatigue is one of the most common challenges facing IT teams, DevOps engineers, and managed service providers (MSPs) today. When dozens (or even hundreds) of alerts arrive everyday, it becomes harder to separate the critical issues from the noise. Engineers miss sleep, teams lose focus, and sometimes the most urgent problems slip through the cracks.
At its core, alert fatigue happens when too many notifications, false alarms, or low-priority alerts overwhelm staff, leading to burnout and mistakes. The cost is high: delayed incident response, reduced productivity, and even turnover among skilled engineers.
In this guide, we’ll break down:
- What alert fatigue is and why it matters
- The most common causes of alert fatigue in IT environments
- The financial and human impact on organizations
- Proven strategies and tools to combat alert fatigue in 2025
Whether you’re an IT manager, on-call engineer, or MSP provider, this guide will help you understand alert fatigue and give you practical steps to reduce it.
What is Alert Fatigue?
Alert Fatigue occurs when IT teams or on-call engineers are exposed to too many notifications, especially low-priority or false alarms, causing them to become desensitized to alerts. Over time, this constant noise makes it difficult to recognize which alerts are truly critical, leading to delayed responses, missed incidents, and increased stress.
In practical terms, signs of alert fatigue can look like:
- Engineers ignoring alerts because they’ve received so many false alarms in the past
- Teams feeling overwhelmed by constant notifications, especially outside work hours
- Critical systems failures being overlooked because they were buried among low-priority alerts
Alert fatigue isn’t just frustrating, it can increase downtime, affect customer trust, and contribute to employee burnout and turnover.
Causes of Alert Fatigue
Alert fatigue doesn’t happen overnight. It builds when IT teams are flooded with constant notifications that lack clarity or urgency. Instead of helping engineers respond faster, these alerts create noise that distracts from the issues that truly matter. By understanding the root causes of alert fatigue, organizations can take targeted steps to reduce unnecessary alerts and keep their teams focused on critical incidents. Alert fatigue causes include:
Too Many Alerts
When establishing your team’s incident management plans it is incredibly important to ensure that on-call engineers are not being bombarded with too many alerts. When systems are generating hundreds of notifications daily, engineers can’t easily identify which alerts are actually critical and require immediate response. High alert volume without prioritization creates a constant background noise that desensitizes on-call staff.
Lack of Context
Alerts that fail to provide relevant details like, which server is down or what priority level an issue is, force engineers to spend extra time investigating instead of acting. Missing context increases frustration and delays response times.
Sleep Disruption
Receiving minor alerts in the middle of the night or outside business hours disrupts sleep and focus. Repeated interruptions contribute to burnout, stress, and even turnover.
Inefficient Alerting Tools
Older or poorly configured alerting systems can send duplicate messages, fail to escalate critical issues, or lack team collaboration features. This makes it harder for teams to respond efficiently and adds to the cognitive overload.
Poorly Defined Roles and Escalation Policies
When it’s unclear who should be handling an alert, teams may waste time figuring out responsibility, further increasing stress and response delays.
The Cost of Alert Fatigue
Ignoring alert fatigue has both human and financial consequences:
- Burnout and Stress: Constant interruptions and unclear priorities erode team morale.
- Delayed Response: Critical incidents may go unaddressed, increasing downtime.
- Turnover: Engineers experiencing chronic alert fatigue are more likely to leave. Replacing them can cost over 50% of their annual salary.
- Reduced Productivity: Time spent sifting through irrelevant alerts is time lost on meaningful work.
How to Combat Alert Fatigue
Reducing alert fatigue requires both process improvements and technology adoption. Here’s a step-by-step guide:
-
Provide Context in Every Alert
Ensure each alert contains actionable details: affected systems, severity, error codes, and suggested next steps. Context allows engineers to respond efficiently without unnecessary, time-consuming investigation.
-
Differentiate and Categorize Alerts
Not all alerts are urgent. Classify notifications as high, medium, or low priority, and suppress low-priority alerts during off-hours. This allows engineers to immediately know whether they have to jump into action to resolve a critical incident or if an alert is more informational/not critical yet, like disk usage at 60%.
-
Use Modern Alerting Tools
Apps like OnPage allow teams to collaborate, escalate alerts, and effectively manage on-call employees. These platforms support attachments, context, and team communication all within the mobile app.
-
Alert the Right Person, Loud and Clear
Creating proper scheduling and escalation paths within your on-call alerting solution ensure that the on duty engineer will receive the notification immediately. No more clicking through documents and emails to figure out who to alert and when. Plus, consider investing in a solution that provides persistent notifications for critical incidents that continue to sound for up to eight hours until acknowledged by the engineer.
-
Conduct Post-Mortems
After incidents occur, review what worked and what didn’t. ASAP. Post-mortems help teams refine alert thresholds, eliminate unnecessary notifications, and improve response protocols.
Conclusion
In summary, alert fatigue is a real and costly challenge for IT teams, DevOps engineers, and MSPs. By understanding its causes, recognizing its costs, and implementing contextual alerts, priority differentiation, modern tools, and post-mortems, organizations can reduce burnout, improve response times, and retain skilled engineers.
Keeping alert fatigue under control is not just about reducing noise, it’s about creating sustainable, efficient, and proactive IT environments.
💡Tip: Always update alerting strategies to reflect current workloads and technologies. Fresh, actionable practices are the key to keeping teams alert, focused, and effective.
