i need to construct a form search in a dashboard that brings back the vpnpool ip address's of any username i type into the input field, im at a loss as how to do this.
This link is a good place to start: http://www.splunk.com/search/docs?q=dashboard
It is a search for dashboard entires in the documentation in the general sense.
This link is to the specific doc entry on form creation: http://www.splunk.com/base/Documentation/latest/Developer/FormIntro
Try to drop this code into your dashboard panel to give a general sense of how forms can work:
<form>
<label>My form search</label>
<searchTemplate>$username$</searchTemplate>
<fieldset>
<input type="text" token="username" />
</fieldset>
</form>
