Log File Analyzer for Java developers [closed]

Question

Sorry to raise this question. But I see a need to update the best log analyzer tools list.

I used BairTail. It's simple and fast. But the development stopped in 2007 and never updated thereafter and no search functionality for free users

Then moved to LogExpert, it's good and free with search functionality. But it's damn slow when log size goes by 2-3mb and scrolling is pain

Apache Chainsaw, other than it's from Apache, i would say it's pretty hard for developer who wants to analyze logs bit fast without doing all regex and manual work. It's too much deviation from normal usage and pretty slow

Please suggest one good/best Log Analyze tool [freeware]

1. Simple Search functionality and highlight is must
2. Should run smooth with minimum cpu resources
3. It will be used upto analyzing 30-50mb files
4. Scrolling and GUI friendly. I use in windows environment and need GUI tools only

Answer 1

I used otroslogviewer to analyze generated logfiles on windows. I used it with 500MB files without any performance or stability. It's free, open scource and the development is still active. It has a pattern auto detect for Java.util.logging or you can pass in your PatternLayout from log4j or describe your custom setup to parse the log messages. You can search (optional with RegEx), mark and filter results and use highlighting (for stacktraces or XML etc.). It's the best choise for me, I found in the web.
