Log aggregation queries (Elasticsearch, Splunk)

Anomaly detection in log streams

Approach

Start with error symptoms, work backward to cause

Look for patterns across time windows

Correlate errors with deployments/changes

Check for cascading failures

Identify error rate changes and spikes

Output

Regex patterns for error extraction

Timeline of error occurrences

Correlation analysis between services

Root cause hypothesis with evidence

Monitoring queries to detect recurrence

Code locations likely causing errors

Focus on actionable findings. Include both immediate fixes and prevention strategies.
