Policies are visual representations of your data center operation procedures. Policies are built by dragging and dropping objects and connecting them with links. When triggered, each object performs an action. Once an object has completed it will trigger any objects that are linked to it.
Each object performs a specific action when it is executed by the Action Server. To use an object, drag-and-drop it to the Policy, configure its properties, and link it to the object that will trigger it. For example, the Send Email object is used to send email through an SMTP server. To use the Send Email object you must configure the recipients, subject, message body, and the SMTP server.
All objects produce data that is published to the Databus. This data will automatically be made available to objects further down the flow without any need to create symbolic variables for storage. To learn more about the databus, see “CROSS_REF”
Some objects are triggered by external applications and cannot be triggered by another object. These objects are called Monitors. Monitors are used at the beginning of Policies to create start conditions. For example, the Monitor Folder object will wait for the files within a specified folder to change. When a file changes the Monitor Folder object will trigger the next object in the Policy.
Policies can only contain one starting point. See our best-practices guide for more information.
Links are used to connect objects and create the order in which they are triggered. Links can be configured with Link Conditions that will filter data from the previous object in the Policy. The filters can test any data published to the Databus. With Link Conditions, you can build automatic decision making in your Policies.
