Discovery process overview

Discovery is a multilevel process that collects configuration information about the entire application infrastructure, identifying deployed software components, physical servers, network devices, virtual systems, and host data that is used in the runtime environment. Discovery is performed using sensors that are part of TADDM product.

The job of the sensor is to discover configuration items (CIs), create model objects, and persist the model objects to the TADDM database. The sensors use protocols that are specific to the resources that they are designed to discover. The following protocols are examples:
  • Cisco Discovery Protocol (CDP)
  • Java™ Management Extensions (JMX)
  • Secure Shell (SSH)
  • Simple Network Management Protocol (SNMP)
  • Structured Query Language (SQL)
When possible, a secure connection is used between the TADDM server and the target systems.

TADDM does not run discoveries over IPv6 networks, but IPv6 attributes are discovered by discoveries running on IPv4 networks.
