# Diagnostics - Threads

> The Threads page displays a snapshot of information about Gateway’s execution threads. This information may be important when troubleshooting certain types of issues. If you are working with Support, you may be asked for a thread dump.

Their state and CPU usages are displayed to easily find problem threads, as well as a chart of what systems are using the threads and the ability to filter the threads based on a keyword. Each thread can be expanded to give details on what it is currently doing, and that individual thread process can be copied to the clipboard.

## Thread Performance by System
The upper section of the Diagnostics - Threads page depicts graphical representation of the current threads including percentage of total CPU used, overall scope, and average CPU usage per system. 
* Click the **Expand** ![expand icon](expand-icon.png) icon to see the display.
* Click the **Reset** ![reset icon](reset-icon.png) icon to reset the information.

## Individual Threads
The lower portion of the Diagnostics - Threads page displays statistics for individual threads. 

To download a thread dump, click the **Download** ![download icon](download-icon.png) icon on the right of the page. In order to be useful, a thread dump must be taken at the time the issue is observed. Unlike logs, which maintain a record of past messages, a thread dump is a time-specific snapshot and will not contain a record of past states. To see more information on thread dumps, including other methods of obtaining them such as [system functions](appendix\scripting-functions\scripting-functions.md) or the command line, click [here](https://support.inductiveautomation.com/hc/en-us/articles/4584702794509-How-To-Take-a-Thread-Dump).
