I am about to use the horizon_chart visualization located in on "visualizations app (VIS_APP)" i created, so I copied the structured tree to my app and defined visualizations.con and default.meta in order to use it in order apps.
It works just fine.
But if I had horizon_chart_app installed, my dashboards return an error saying they can't find horizon_chart visualization in VIS_APP. If I disable horizon_chart_app, it returns to work.
What is happening? What makes Splunk look into horizon_chart_app by default even when I tell him to look at one specific app VIS_APP?
I faced the same problem recently and changing the visualization's name inside of my app did the trick. All you have to do is change the name to "horizon_chart_viz", or any other name, as long as it is different from the original visualization's name:
Change the visualization stanza inside the "visualizations.conf" file to "[horizon_chart_viz]"
Change the visualizations stanza on the "default.meta" file to "[visualizations/horizon_chart_viz]"
Change the name of the folder containing the visualization to "horizon_chart_viz" (on /etc/apps//appserver/static/visualizations/)
@TiagoTLD1 Horizon Chart is one of Splunk's Custom Visualization (similar to inbuilt visualizations but available as individual apps on Splunkbase). This can be either made available only to System app or All Apps from Horizon Chart > App Permission settings:
