What is difference between discover server and discovery agent probe ..And these both the probes must be functioned only in primary UIM server or it can be distributed across remote hubs .
The Discovery Server probe is a singleton in terms of how many instances are deployed in the UIM environment. This probe is responsible for inserting inventory information into the database. The probe requires the probeDiscovery and udm_inventory queues to be functional on the primary hub. Many different probes will insert messages onto the bus to be sent to the Discovery Server. For instance, Discovery Agent (described below), SNMP Collector and VmWare all contribute to inventory information. The list I just provided is non-exhaustive. Just a few short examples.
The Discovery Agent is able to be off loaded from the UIM hub. You can deploy this probe many times throughout the environment. The probe exists to discover remote server and network infrastructure. Once devices have been found by this probe a user is able to deploy robots to the servers via the "Actions" button in USM. A user is also able to create filters in the SNMP Collector Probe for any devices found to respond to SNMP. You will find that the Discovery Wizard in USM is the launch pad for configuring Discovery Agents. In this UI, you can define Authentication Profiles (usernames and passwords), the Network Scopes (IPV4 or IPV6) and even the schedule for agents to run on.
Please let me know if this answers your questions.
Thanks Mathew ,So configuring discovery agent on remote hub is a best practice..kindly suggest .
