log analyzer quarkus

Troubleshooting Quarkus logs in production or dev mode often leads to a rabbit hole of CDI resolution errors and SmallRye configuration codes. This skill parses JVM and GraalVM native logs to identify the root cause of failures in io.quarkus applications.

What it does

• Standardized Log Parsing processes Quarkus-specific formats including category packages and thread names.
• Error Pattern Matching identifies specific codes like SRCFG configuration failures and UnsatisfiedResolutionException CDI issues.
• Sensitive Data Detection flags PII, JWT tokens, and database credentials that must be redacted or secured.
• Native vs JVM Analysis adjusts diagnostic logic for compressed GraalVM stack traces versus verbose JVM outputs.
• Structured Reporting generates a professional executive summary with severity levels and root cause hypotheses.

How it works

1. Initial Screening identifies missing context such as environment (PROD/DEV) or truncated stack traces.
2. Chain Tracing follows the Caused by: sequence to find the originating component.
3. Pattern Correlation matches log events against known Quarkus failure modes like JDBC connection pools or SmallRye health checks.
4. Diagnostic Output produces a formatted report with critical findings, warnings, and clear next steps.

Frameworks & tools

Specifically built for Quarkus, GraalVM, SmallRye Config, ArC (CDI), Netty, and JAX-RS (RESTEasy).

Why this beats prompting it yourself

Generic LLMs often miss the specific meaning of SmallRye error codes or fail to notice when a GraalVM native stack trace is misleading. This skill uses a strict diagnostic guide to avoid reporting cascade errors as primary causes.

Use cases

• Debugging UnsatisfiedResolutionException during complex CDI bean injections.
• Identifying specific missing properties signaled by SRCFG00014 or SRCFG00040 codes.
• Auditing logs for leaked secrets like Bearer tokens or internal hostnames.
• Root cause analysis for JDBCConnectionException in high-load environments.

Known limitations

Cannot fix code directly. Requires manual input of application.properties for configuration-related root cause verification. Limited accuracy with heavily truncated logs using ...X more.
