Discovery configuration files

Experienced users can configure the discovery by editing the discovery configuration files.

To configure the discovery using the command-line interface (command line), edit the discovery configuration files and create or edit inserts into the databases of the discovery processes.

Note: The DiscoSchema.cfg configuration file contains the schemas for all the discovery databases. Unlike the files listed below, the DiscoSchema.cfg configuration file contains no insert statements. You can view this file but it must not be edited.

When ncp_disco is running, it periodically scans the agents and stitchers directories and loads any new or modified stitcher and discovery agent definitions.

Table 1 shows which configuration files to edit to configure the discovery, and whether the configuration can also be done using the Discovery Configuration GUI.
