This is a followup to a prior post about CallManager Express and Splunk integration.
One of the really handy features in Splunk is the ability to run a search in CLI and save the output in various formats, like CSV and XML. I put together a small script and an XSLT file to transform the XML output of the scripted report into an HTML document with all the important information, for use in a dashboard page.
Here is an example piece of XML from the report to show the schema:
<searchResults timestamp="01/14/2009:11:12:37">
<command>QUERY GOES HERE|replace 5206 with SomeLine in dialed_number|fields + a_date,weekday,date_hour,date_month,date_mday,dialed_number ] | outputxml</command>
<results type="message">
</results>
<results type="unknown">
<cols>
<col cd="1" dc="32">a_date</col>
<col cd="3" dc="21">date_hour</col>
<col cd="5" dc="31">date_mday</col>
<col cd="4" dc="2">date_month</col>
<col cd="6" dc="9">dialed_number</col>
<col cd="2" dc="7">weekday</col>
</cols>
<r>
<m col="1" cd="625ec574">01/14/2009</m>
<m col="3" cd="5970c7">11</m>
<m col="5" cd="5970ca">14</m>
<m col="4" cd="cda985df">january</m>
<m col="6" cd="e13fb9d">Sales</m>
<m col="2" cd="67a9b049">wednesday</m>
</r>
---ETC---
So, you see that <cols> holds your column headings and <r>s are somewhat analoguous to rows in a CSV file.
Below is a smattering of chunks of the XSL file.

You can use cron to schedule and something like XML Starlet to run the transform the XML to HTML using the XSLT.
