Query¶

let AppName = "my-container-app";

Example Output¶

Interpretation Notes¶

• High-frequency identical errors are good candidates for first remediation.
• Noise reduction improves on-call signal quality.
• Normal pattern: healthy mix of informational logs with low repetitive errors.

Limitations¶

• Does not group semantically similar but text-different messages.
• Large dynamic fields can fragment counts.
