Building Advanced Dashboards - Implementing Splunk: Big Data Reporting and Development for Operational Intelligence - page 224

This query will produce a "V" from our random req_time field, as shown in the
following screenshot. See the maps documentation at splunkbase.com for more
information about the _geo field:
This is a very simplistic example, using the default settings for nearly everything.
For a more complete example, see the Google Maps dashboard included
with the Google Maps app. You can see the source code in the manager,
or by using the showsource attribute. On my server, that URL would be
http://mysplunkserver:8000/en-US/app/maps/maps?showsource=1 .
Sideview Utils
Sideview Utils is a third-party app for Splunk that provides an alternative set
of modules for most of what you need to build an interactive Splunk dashboard.
These modules remove the complexity of intentions, make it much easier to build
forms, make it possible to use variables in HTML, and make it much simpler to
hand values between panels and dashboards.
We will use a few of the modules to build forms and link multiple dashboards
together based on URL values.
An older but still functional version of SideviewUtils is available through
Splunkbase. You can download the latest version from http://sideviewapps.com/ ,
which adds a number of features, including a visual editor for assembling dashboards.
