Seeding an EMS discovery

Seed the EMS discovery by seeding the Collector finder. This is typically a one-time setup task required when a new collector is added to your installation.

About this task

To enable Network Manager to find the collectors, you must seed the Collector finder. Seeding the Collector finder involves specifying for each collector:

The hostname of the device on which the collector is running.
Note: The hostname is not required when the collector is running on the same server as the Network Manager discovery.
The port on that device on which the collector is listening.

If a collector is running on the same host as Network Manager, then you need only specify the port.

Note: If you are rediscovering a device using the Collector finder, then specify the IP address of the device or subnet to rediscover using the Discovery Configuration GUI.

You can seed the Collector finder to perform a discovery or to perform a partial rediscovery of a single device or subnet. If you seed the Collector finder to perform a partial rediscovery, then you can also specify a single device or subnet retrieved by the collector.

Note: If you are seeding a Java collector discovery for Network Manager Fix Pack 17 and above, you must configure the m_HelperType as Java.

Seeding the Collector for a first discovery

You seed the Collector finder for a first discovery by appending an insert into the collectorFinder.collectorRules table to the DiscoCollectorFinderSeeds.cfg configuration file. The following insert seeds the Collector finder with a host name of 172.16.25.1, and a port of 8082. This insert means that the collector is running on a host with IP address 172.16.25.0, which is different to the host on which Network Manager is running. The override number of retries for this collector is 5.

insert into collectorFinder.collectorRules
(
        m_Host,
        m_Port,
        m_NumRetries
)
values
(
        "172.16.25.1",
        8082,
        5
);

For Fix Pack 17 and above, if the collector is a Java collector, set the m_HelperType field as in the following example.

insert into collectorFinder.collectorRules
(
        m_Host,
        m_Port,
        m_NumRetries,
	  m_HelperType
)
values
(
        "172.16.25.1",
        8082,
        5,
	  “Java”
);
