# Live Performance Data and Probes

Provided the user has access to trace and performance data for a given server, the user can explore the live performance of a running server and can insert probes to see the live data for any given chain point through-out the rules. This is an excellent debugging tool that can even be used on productions servers.

To obtain live performance data, go to the server status and click to retrieve the server performance as normal. If you have the ability to trace and view performance for the server, some additional options will show:

In the **View live** section, click on **View Rules Performance** to see the live performance of your rules:

You can not only see the number of transactions flowing through each rule, you can also see the live properties of the rule set in use. The data and rule sets visualized for the live view are all extracted from the server. The transaction counts will update every 5 seconds.
