Third-party add-ons

There are many excellent apps available at http://splunkbase.com, a number of which provide custom modules. We will cover two of the most popular, Google Maps and Sideview Utils.

Google Maps

As we saw in Chapter 8, Working with Apps, the Google Maps app provides a dashboard and lookup to draw results on a map. The underlying module is also available to use in your own dashboards.

Here is a very simple dashboard that uses the GoogleMaps module:

<?xml version="1.0"?>
<view template="search.html">
<!-- chrome -->
<label>Chapter 9 - Google Maps Search</label>
<module name="AccountBar" layoutPanel="appHeader"/>
<module name="AppBar" layoutPanel="navigationHeader"/>
<module name="Message" layoutPanel="messaging">
<param name="filter">*</param>
<param name="clearOnJobDispatch">False</param>
<param name="maxSize">1</param>
</module>
<!-- search -->
<module name="SearchBar" layoutPanel...
