# My Patterns

# Introduction

The "My Patterns" feature allows users to define custom patterns by specifying a pattern name and a corresponding stack trace. When a thread report is generated, the system will highlight the specified stack trace in yellow for any matching threads. This feature enhances the visibility of specific thread traces, making it easier for users to identify and analyze relevant information in the thread report

# Feature Overview

The key functionalities of the "My Patterns" feature include:

  • Pattern Creation: Users can create custom patterns by providing a unique pattern name and the associated stack trace.

  • Thread Report Highlighting: When a thread report is generated, the system compares the defined patterns with the thread traces. If a match is found, the corresponding stack trace in the thread report in my pattern section highlighted in yellow.

  • Matching Threads List: In the "My Patterns" section, users can view a list of threads that match the defined patterns. The system provides a convenient way to identify and explore the threads associated with each pattern.

# Examples

# Creating a Pattern

Pattern Name: DatabaseConnectionIssue
Stack Trace: 

at com.example.DatabaseConnector.openConnection(Databaseconnector.java:50)
at com.example.Application.runQuery(Application.java:100)

There is no strict limit on the number of patterns you can create, but it's recommended to keep the list manageable for better usability.

# Conclusion

The "My Patterns" feature empowers users to customize thread reports, making it easier to identify and focus on specific stack traces of interest. Regularly review and update patterns to ensure they align with the evolving needs of your application.
