In most installations, the discovery_server probe runs on the primary hub. The probe performs these major tasks:
  • Configures discovery agents and collects status from them.
  • Collects information about the UIM Server infrastructure: hubs, robots, probes, packages, monitored systems or devices, monitored subsystems or items and monitored metrics.
  • Collects device data from probes that publish discovery information.
  • Applies correlation rules to associate new device records, where appropriate, with any already-existing master device records. One example is to represent multi-homed devices (devices with multiple network interfaces) accurately.
The information that is collected by the discovery_server probe is stored in the UIM Server database and used by other UIM Server components. The discovery_server probe also helps maintain the database by expiring inactive systems that don’t have any associated QoS data.
: Even without any discovery_agent probes deployed, the discovery_server probe is still needed to generate the data required by other components.
