Elasticsearch - ELK Stack Integration
You created an anomaly detection job but see no results after starting the datafeed. What is a likely cause?
AThe job was deleted before starting
BThe Elasticsearch cluster is offline
CThe datafeed is not running or has stopped
DThe anomaly scores are all zero
Step-by-Step Solution
Solution:
  1. Step 1: Check datafeed status

    If no results appear, the datafeed may not be running or has stopped feeding data to the job.
  2. Step 2: Evaluate other options

    Job deletion would prevent starting datafeed; cluster offline causes broader failures; zero scores still produce results.
  3. Final Answer:

    The datafeed is not running or has stopped -> Option C
  4. Quick Check:

    No results usually mean datafeed stopped [OK]
Quick Trick: No results? Check if datafeed is running [OK]
Common Mistakes:
MISTAKES
  • Assuming zero scores mean no results
  • Ignoring datafeed status
  • Blaming cluster offline without checking datafeed
