You configured this alert:
if cpu_load > 80% then alert

No alerts are triggered despite high CPU load. What is a likely reason?
AThe alert rule syntax is incorrect
BCPU load is not a valid metric for alerts
CAlerts only trigger when CPU load is below 80%
DThe alert lacks a duration condition to avoid transient spikes
Step-by-Step Solution
Solution:
  1. Step 1: Analyze alert rule

    The rule triggers alert immediately when cpu_load > 80%.
  2. Step 2: Consider transient spikes

    Without a duration, brief spikes may not trigger alerts or may be ignored by the system.
  3. Step 3: Identify likely cause

    Lack of a duration condition means alerts may not fire as expected.
  4. Final Answer:

    The alert lacks a duration condition to avoid transient spikes -> Option D
  5. Quick Check:

    Does the rule specify duration? No [OK]
Quick Trick: Alerts need duration to avoid false negatives [OK]
Common Mistakes:
MISTAKES
  • Assuming CPU load is invalid metric
  • Thinking alerts trigger on low CPU load
  • Believing syntax is incorrect without evidence
