When there are several hundreds or thousands of threads in the thread dump, the user might want to search threads based on thread name, thread Id, stack trace … Here are a few sample cases:
- Find all the threads which are executing a specific class
- Find all the threads which are executing a specific method
- Find all the threads whose name begins with ‘ajp-bio-‘
- When multiple thread dumps are uploaded, the user might want to search what a specific thread was doing across multiple thread dumps
- Find all the threads which have priority ’10’
To facilitate such searches, fastThread provides ‘search’ functionality in the application.

At the right top corner of the fastThread report, you will see a ‘search this thread dump’ text field. In this field you can enter search term with which you want to search the threads. When you enter the search terms and click on the search button, you will be taken to a new thread search results page. In this page matching thread results will be shown.
Advanced Search
Tool also provides advanced search capabilities. When you click on the ‘Advanced Filter’ button in the thread search page, a search panel is show-up.

- Regular expression
- Match Case
- Whole words
Search Fields
Using this option, you can search on various thread fields:

You can also combine ‘Search Fields’ and ‘Search Options’ and search for the Threads.

Could you explain HOW can I combine two or more search fields using “AND” rule.
E.g. I need to find all threads with name matching “http-nio-localhost-8080-exec.*” , which has RUNNABLE state.
All I was able to get was all threads with name matched the string OR state is RUNNABLE. I.e all runnable threads + some waiting with name match, which is obviously useless

Hello Dennis! Indeed very interesting prespective. Currently our search doesn’t support the ‘AND’ requirement you are asking. May be we need to provide something similar to JQL (provided in JIRA) to suppport this requirement.
