Tomcat Stuck Thread Log Parser

Compare different implementations to count stuck threads in multiple log files.

After an initial comparison, further features will be implemented in Java.

Test all implementations (with bats)

First, install bats.

Run tests

bats tests.bats

Generate custom performance comparison report

# Script with folder and prefix for a custom subset
./generate-report.sh ./tomcat-log-examples example-2022-06-01

The example reports in count-stuck-threads.md was generated with a private 5 GB dataset which is not attached to the repository for several reasons.

Usage for Java CLI

cd java

# Count stuck threads per line (async)
./build-and-run.sh ../tomcat-logs/ --async

# Show most common codeline per file
./build-and-run.sh ../tomcat-logs/ --analyze-code-line-occurrences
