Example text

If the OVO product is loaded and configured with the basic events and templates deployed, the system will be inundated with information about the monitored systems. Most of this information will be unwanted, unnecessary, and duplicated. Literally tens of thousands of events and messages can easily be generated on a daily basis if the default templates and traps are deployed out-of-the-box. It is virtually impossible to peruse through fifty thousand messages on a daily basis. The same concept applies to NNM.

If the information cannot be retrieved from the SNMP agent, another way will have to be devised, possibly through an OVO action, command, or monitor, or some other method or add-on product. Tip When using NNM Threshold and Monitoring, only numeric variables can be retrieved for status checking. Polling for changes in text cannot be done. 2 OpenView Operations OVO is agent based, meaning that an agent is deployed to the node and alarms (messages) are sent to the OVO Management station based upon the templates assigned to the node.
