This product usually uses the communication mode in which data is "pushed" from Agents (or Proxy Managers) to the Manager. However, communications using the Push method are not always appropriate, such as with Internet environments where the managed servers are in the DMZ and communications options are limited. In such situations, configure communication environment using the Pull method.
Pull type communications are initiated by the Manager, which polls the Agents (or Proxy Managers) and pulls the results from them. These communications use the HTTP protocol and so require an HTTP communications environment on the Agents (or Proxy Managers).
Point
The communication mode is Push when installing Agents (or Proxy Managers). Switch the communication mode in order to use pull communication.
For push communications, Agents (or Proxy Managers) send data autonomously, and so no particular definitions need to be made. For pull communications, definitions for the Agents and Proxy Managers from which data will be "pulled" must be defined on the Manger.
Note that push and pull communications cannot be used together on the same Agent or Proxy Manager.
Refer to the following sections for installation methods that are based in configuration models in pull communications mode:
