You set an alert to notify your team when memory usage exceeds 90%, but no alerts are received even though memory usage is high. What is the most likely cause?
ANotification channel is not configured correctly
BMemory usage metric is not collected
CAlert condition threshold is set too low
DAlert duration is set to zero
Step-by-Step Solution
Solution:
  1. Step 1: Check alert condition and metric

    Memory usage is high, so condition threshold is likely correct and metric is collected.
  2. Step 2: Verify notification setup

    If no alerts are received, the notification channel (email, Slack, etc.) may be misconfigured or missing.
  3. Final Answer:

    Notification channel is not configured correctly -> Option A
  4. Quick Check:

    No alerts + correct condition = notification issue [OK]
Quick Trick: Check notification setup if alerts not received [OK]
Common Mistakes:
MISTAKES
  • Assuming threshold is always wrong
  • Ignoring notification channel setup
  • Thinking metric collection is always faulty
