In this second installment of a two-part series, we’ll be going over Phase Two, the build out of standard pre- and post-patching automation, and Phase Three, the build out of application-specific pre- and post-patching automation. Click here for Phase One. Status Report With basic patching and reboots automated, a patching session for application environments without any special pre-patching and post-patching activities was reduced from 20 minutes per server, down to 6 minutes per server.

ServiceNow also provides you with a REST API Explorer that uses information from your instance to provide you with a list of endpoints, methods, and variables that you can use to build and send a REST request.
