All device nodes which match the filter created in Filtering the root device node are synchronized to the CMDB. After a node has passed the first filter, the synchronization system retrieves the source subgraph of all the relevant related nodes, known as its components. Before the source subgraph is transformed into the target subgraph, nodes can be excluded from the source subgraph using the Component Filter. If nodes are excluded from the subgraph, the transformation into the CMDB model proceeds as if the excluded nodes did not exist in the Discovery data store.
Currently the labels in the Component Filter show the node type and a brief description. For generic nodes such as Details, the description is insufficiently detailed to identify which node is selected. You need to check the CMDB after synchronization to ensure that the correct node is selected.
Filtering components from the UI
On the Component Filter tab,
The following example shows how to use the Filter Builder to create a filter that will synchronize only those software instances representing web servers on those hosts previously identified as web servers.
Type
attribute.Type
attribute.With this filter in place, any Software Instances (SIs) that do not match the conditions are removed from the source subgraph. When the source subgraph is transformed into the target subgraph, it is as if the chosen SI nodes were the only ones present in the Discovery datastore.
