What is API Log Analyzer?

API Log Analyzer turns copied server logs into a compact summary for incident triage, support escalation, and backend debugging.

Analyze API logs for ERROR/WARN/INFO counts, duplicate exceptions, correlation IDs, and timeline buckets.

How to use API Log Analyzer?

Step 1

Try the included example input, then replace it with a redacted sample from the system you are debugging.

Step 2

Paste a focused log window around the failing request.

Step 3

Review level counts, duplicate error groups, request IDs, and timeline buckets.

Step 4

Copy the summary and include only redacted lines in tickets or chat.

Example input / output

Use API Log Analyzer to inspect a representative sample, confirm the result and continue to a related validation, conversion or comparison step if needed.

Compare the generated output with the included expected result and check that meaningful values were preserved.

Example input

2026-05-17T12:00:02Z ERROR requestId=abc-1 java.lang.IllegalStateException: Duplicate key

Example output

ERROR/WARN/INFO counts, correlation IDs, duplicate exception groups, timeline buckets, and extracted exceptions.

Practical developer examples

Check a copied value

Use API Log Analyzer on a small, redacted sample from a request, response, Log, test fixture or configuration file. Compare the result with the source before reusing it.

Document the result

Include the relevant input, selected action, output and expected behavior in a ticket or code review so another developer can reproduce the same check.

Common developer use cases

API Log Analyzer handles a focused transformation or inspection in the browser so you can answer one debugging question without creating a temporary script or project file.

Common issues

Logs without timestamps or correlation IDs are harder to group accurately.
Multiline stacktraces copied from terminals may need the Java Stacktrace Analyzer for deeper frame extraction.

FAQ

Does API Log Analyzer send data to a server?

The interactive transformation is handled in the browser in this frontend build. Analytics and advertising scripts may still load separately for site measurement or ads readiness, so avoid pasting active secrets or regulated personal data.

What input works best in api log analyzer?

Paste raw application logs directly into the input area or use the example button for a quick starting point.

Can I share API Log Analyzer output with teammates?

Yes, but review the result first and redact tokens, private keys, customer data, internal URLs, account IDs, and other sensitive values before sending it in a ticket, chat, or pull request.
