 ### Sessions
 
+#### How do I find my session ID?
+
+##### Background
+
+When a Posit Workbench session is requested by the user, it is assigned a session ID. This is a long string of letters and numbers that uniquely identifies the session. The session ID corresponds to metrics and logs that are produced by the Posit Workbench application and collected for onward analysis and debugging of issues.
+
+##### Steps to find out the session ID of your Posit Workbench session
+
+1. If you have not already done so, log into Posit Workbench and start a session (refer to the [guidance on the Knowledge base here](https://public-health-scotland.github.io/knowledge-base/docs/Posit%20Infrastructure?doc=How%20to%20Access%20Posit%20Workbench.md#logging-in) if necessary).
+
+2. After the session has started, navigate to the [Posit Workbench homepage](https://pwb.publichealthscotland.org) and identify the session for which you would like to obtain the session ID in the list of sessions, as circled in red below:

+
+3. Click the "Info" button of the session (highlighted in yellow above) to bring up a dialog box containing further information about the session:

+
+4. Click on "Launcher Diagnostics" (highlighted in yellow above) to view a tab with further details:

+
+5. The session ID of the session is highlighted in yellow above - it is a long string of letters and numbers.
+
+6. To close the dialog box, click the "Close" button, circled in red above.
+
+##### Alternative method
+
+The session ID can also be found in the URL (i.e. web address) when a session is open. This method can be useful to capture the session ID of a session that has crashed or failed to launch successfully. In the address bar of your web browser, you will see a URL like the one below:
+
+```
+https://pwb.publichealthscotland.org/s/bd664cfc78a31605322d7/?launcher=1
+```
+
+The long string of letters and numbers (in this case <code>bd664cfc78a31605322d7</code>) is the session ID.

 #### <a name="sessions-502-504">Why do I get _Status code 502/504_ errors when starting a session and what can I do about it?</a>
 
 _Status code 502/504_ errors are produced when the Posit Workbench application is unable to connect to your RStudio IDE session.  This will most often happen when you are starting a session, especially when you have requested a large session as these take longer to start.
