public String getClientRequestToken() {

<p>
The token passed to the operation that generated this event.
</p>
<p>
All events triggered by a given stack operation are assigned the same client request token, which you can use to
track operations. For example, if you execute a <code>CreateStack</code> operation with the token
<code>token1</code>, then all the <code>StackEvents</code> generated by that operation will have
<code>ClientRequestToken</code> set as <code>token1</code>.
</p>
<p>
In the console, stack operations display the client request token on the Events tab. Stack operations that are
initiated from the console use the token format <i>Console-StackOperation-ID</i>, which helps you easily identify
the stack operation . For example, if you create a stack using the console, each stack event would be assigned
the same token in the following format: <code>Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002</code>.
