You can configure VMware polling interval defaults, retries, and time-outs by using the Polling and Thresholds Console of the Domain Manager Administration Console.
Through the default polling groups for the Server Manager, you control the polling of the managed objects in your network. The polled data serves as input to the Server Manager root-cause and impact analysis.
Appendix E, Polling Groups and Settings, provides additional information about polling.
VMware, Inc. recommends that you do not change the default settings.
