splunk-add-on-ucc-framework
A framework to generate UI based Splunk Add-ons. It includes UI, Rest handler, Modular input, Oauth, Alert action templates.
Note: after UCC 5.2 Python 2 specific libraries are not supported anymore. This means if the add-on has
package/lib/py2/requirements.txt
they will not be installed while runningucc-gen
command. Therefore modular inputs that are supposed to run on Python 2 will not be supported by UCC.
What is UCC?
UCC stands for Universal Configuration Console. It is a service for generating Splunk Add-ons which is easily customizable and flexible. UCC provides basic UI template for creating Addon's UI. It is helpful to control the activity by using hooks and other functionalities.
Features
- Generate UCC based addons for your Splunk Technology Add-ons
UCC 5
UCC 5 has potentially breaking changes to add-ons using hook extension in the UX. Previously such hooks were limited to un-optimized js files placed in the package. Add-ons may now package such extensions with webpack.
Requirements
- Addon package and globalConfig.json file
Note: You may refer the globalConfig.json file here
