NNMi Integration Job

Defines whether the integration should discover disabled IP addresses.

When setting to false, the integration does not discover disabled IP addresses.

Default: false.

discoverLayer2

Defines whether the integration should discover the Layer2Connection CIs from NNMi.

When set to true, the integration fetches all the Layer2Connections-related data, iteratively querying for a specified number of Layer2Connections from NNMi (based on value of the pageSizeLayer2 parameter), then querying for Network Interfaces on the ends of Layer2Connection and Nodes hosting these interfaces with instant push of collected topology to UCMDB.

Default: true

discoverNodes

Defines whether the integration should discover all the Nodes that are registered in NNMi, regardless of their inclusion into Layer2 Topology or VLANs.

When set to true, integration fetches all the Nodes with connected IpAddresses, Interfaces, HardwareBoards, Physical Ports and IpSubnets, iteratively querying for a specified number of Nodes with related data from NNMi (based on value of the pageSizeNodes parameter) and instantly pushing collected topology into UCMDB.

Default: true

Defines whether the integration should discover non-managed interfaces.

When set to false, the integration does not discover non-managed interfaces.

Default: false.

Defines whether the integration should discover non-managed nodes.

When set to false, the integration does not discover non-managed nodes.

Default: false.

When this parameter is set to true, discoverDisabledIps and discoverNonManagedInterfaces are ignored for non-managed nodes; the integration will discover everything, including disabled ips and non-managed interfaces.

discoverPhysicalPorts

Defines whether the integration should discover physical ports.

When set to false, the integration does not discover physical ports.

Default: false.

When this parameter is set to false, the integration does not discover VLANs and HardwareBoards.

discoverVlans

Defines whether the integration should discover all the VLANs that are registered in NNMi.

When set to true, integration fetches all the VLANs with member Physical Ports, Hardware Boards and Nodes hosting those Physical Ports and Node-related topology, iteratively querying for a specified number of VLANs (based on the value of pageSizeVlans parameter), getting all the necessary related topology and instantly reporting it back to UCMDB.

Default: true

This parameter is ignored if discoverPhysicalPorts is set to false.

Specifies the adapter's mode of execution, either related or full.

Default: related

• In related read mode, only a small subset of the topology is read, starting from the root entity. For example, the following is possible:

  • read several Nodes

  • read all entities related to these Nodes, including Interfaces, Ip Addresses, Ports, and so on.

  • send date to UCMDB

  • continue with other Nodes

• In full read mode, the entire topology is read into memory before the data is processed and result vectors are formed. This approach requires more memory, but reduces the number of requests to the NNMi server. The job sends the topology in chunks after more than 10,000 objects are accumulated for sending. The Data Flow Probe then processes these chunks and sends them to the UCMDB server.

  Use the remoteJVMArgs parameter of the integration adapter to increase the memory limits for the remote Java virtual machine that executes the job, in case there is a lot of data in NNMi. For example, setting the value of the remoteJVMArgs parameter to Xmx4096m enables the remote JVM to consume up to 4 GB of memory. As a general rule, reading 2 million objects from NNMi consumes approximately 10-12 GB of memory.

  For full read mode, it is recommended to set all page sizes to 1000 (using the pageSizeLayer2, pageSizeNodes, and pageSizeVlans parameters.

pageSizeLayer2

Defines the number of Layer2Connection CIs to fetch from NNMi per one query.

Default: 5

pageSizeNodes

Defines the number of Nodes to fetch from NNMi per one query.

Default: 10

pageSizeVlans

Defines the number of VLANs to be queries from NNMi per one query.

Default: 1

Enables global querying for custom attributes of entities in the script. The script must still be modified to read the values and report them (this code modification is expected to be made by the customer). Without modification to the script, setting this parameter to true has no effect. For performance reason, by default, custom attributes are not read from the NNMi server .

Default: false

Defines whether to run the adapter in the external JVM.

Default: false
