Changing Text Colour In a Dashboard

[itsomana]

I have a traffic light dashboard configured and was wondering if you can change the white text in the green traffic light box to black. If so could some advise as to how I would go about doing it.

Splunk uses a CSS file to define what colour things appear.
So for example the default one is located in;
$SPLUNK_HOME/share/splunk/search_mrsparkle/exposed/css/skins/default/

If you are working on an app you can copy and paste the application.css file to your etc/apps/APPNAME/appserver/static/ folder to override the default settings.
Of interest is the part;

.SingleValue .severe {
       background-color: #bb2121;
       color: #fff;
}
.SingleValue .high {
       background-color: #e67918;
       color: #fff;
}

This defines the background colour of the different colours. if you wanted you could copy and paste one of those and create your own, maybe called it .SingleValue .reallyBad { and then you just need to use the term reallyBad in place of low, severe etc in your rangemap command. You can then also define your own custom colours but also use the existing ones!

Just some important points, ensure Splunk has access to the file if you copy it over or move it as an admin/root user.
