Looks like the plugin's latest code only works with Kibana 5.0.0. If you have Kibana 5.0.2, which is the latest, you should see an error in the console or the Kibana logs when you start Kibana:
log [18:53:42.601] [warning] Plugin "gauge_sg" was disabled because it expected Kibana version "5.0.0", and found "5.0.2".
You can fix this yourself by editing the plugins/gauge-sg/package.json file in the Kibana directory, and change "version": "5.0.0" to your exact Kibana patch version.
Once I did that, I see the Gauge option in "Create New Visualization", and I have Kibana 5.0.2:
How to use the gauge plugin to generate gauge visualization? I find changing the number of gauge level doesn't make it point to the corresponding gauge section
