Discovering device details (standard)

Edit online

The standard discovery of device details is carried out in several steps.

Figure 1 shows how device details are discovered in a standard discovery.

Figure 1. Discovery Process Flow: Device Details (Standard)  
Concept diagram that describes how device details are discovered in a standard (not context-sensitive) discovery.

The process flow shown in Figure 1 is described below.

  • 1: All the agent despatch tables are active, so an insertion into the Details.despatch table automatically triggers the Details agent to discover basic device information and determine whether SNMP access to the device is available.
  • 2: The Details agent interrogates the network through the Helper Server. Requests are cached to reduce the number of times that the helpers (represented by the letter H in Figure 1) must interrogate the network directly.
  • 3: The information retrieved from the network is returned to the Details.returns table.
  • 4: The information in the Details.returns table is passed to the despatch table of the Associated Address (AssocAddress) agent for processing.
