Consider these best practices for APIs and Integrations.
Use the API when there is a need to automate a well-defined workflow, such as repeating the same tasks to configure access control for new vRealize Operations users. The API is also useful when performing queries on the vRealize Operations data repository, such as retrieving data for particular assets in your virtual environment. In addition, use the API to extract all data from the vRealize Operations data repository and load it into a separate analytics system.
Use manual discovery to perform a port scan through an IP range as an SNMP adapter does not know the location of the SNMP devices that you want to monitor.
Use the Realize Operations Email Template Manager to customize the email template, as the manual method is error prone.
