It is important that whenever a message is generated, the HPOM management server can identify the node generating that message. Otherwise the message would be filtered out and would not have any influence on the status of an HPOM service. Therefore, it is very important that the incoming message belongs to one of the following:
If you only configure the proxy system as a managed node (and not the agentless nodes as shown in the next section), then you have to make sure that all messages that are created by agentless monitoring specify the proxy system as the originating node. This is required because all messages have to be associated with a managed node. If policies set the node property to another node, and this node is not configured as managed node in HPOM, then the corresponding message is discarded.
In addition, you can put the originating node name in the message, for example in the message text or the object box, so that you do not loose this information. This setup can be used if it is not necessary to distinguish between several monitored nodes, and if you do not use the monitored node names in HPOM service definitions. The proxy system is treated as the owner of the problem and messages are shown as messages belonging to the proxy system itself.
The advantage of configuring the monitored nodes in HPOM is that policies can set the node name to the originating node and messages will then show up as messages of the originating node in the message browser. It also allows you to create and use services that are hosted-on monitored nodes. You can configure agentless nodes in the following ways:
In most cases, the nodes that you should monitor agentlessly are already discovered by HP BTO Software integrated products such as HP NNM. You can normally find theses nodes within the Discovered Nodes groups, which are accessible from the Configure Managed Nodes dialog box:
They can be drag-and-dropped directly into the managed node list from the Discovered Nodes group.
The monitored nodes should be set up as follows:
These two types of operating system start these nodes for HPOM management without an HP Operations agent installation.
NOTE:
For Microsoft Windows agentless nodes, avoid selecting any Windows
operating system name. If a Windows operating system name is
selected, automatic deployment is enabled by default, and an HP
Operations agent is installed on the monitored node and it becomes
a standard managed node.
