12.2 THE OVO OPERATOR

The OVO operator is the user responsible for monitoring the environment. The message browser provides the operator with a view of messages and is the focal point of an operator account. The messages in the message browser indicate to the operator that an event has occurred. An event typically indicates that something in the managed enterprise has gone wrong.

The message browser contains ten columns, as shown in Figure 12-4. Each column provides indicators to the operator. At a glance, the operator can determine where the event originated, the severity of the event, and the type of event that occurred.

The operator login provides a toolset enabling the operator to perform a job. The job entails attempting to resolve problems listed by the events in the message browser. The operator login consists of five windows, described briefly in the following list:

• Root
  The root window is a submap containing the hierarchy of all discovered devices in the enterprise.

• Managed Nodes
  The Managed Nodes window contains the managed nodes assigned to the operator. An operator may be responsible for a subset of nodes in an enterprise. Operators are assigned nodes based on the monitored applications and the operator skill set.

• Message Groups
  The Message Groups window consists of message groups assigned to the operator. Message groups contain events generated by OVO agents based on monitored attributes such as database, operating system type, or application name.

• Application Desktop
  The Application Desktop contains applications and application groups assigned to the operator. Applications can be executed by the operator on a managed node without actually having to log into the system.

• Message browser
  The message browser contains messages, message attributes, and status information sent by the managed nodes for which the operator is responsible.

OVO provides a Java-based GUI similar to that shown in Figure 12-5. The java client can be installed on Windows and Unix systems and configured to access the OVO server. The necessary components of OVO are available from the Java-based GUI for an operator to monitor messages and perform routine tasks.

The operator has the ability to limit the messages in the view by setting the filter as shown in Figure 12-5. An additional feature available with the Java-based GUI is the ability to click on a column to sort messages. By default, messages are sorted according to the timestamp. If you were to click the

[Node] button at the top of the Node column, the messages would be sorted alphabetically by node name.
