PostgreSQL discovery

Discovery creates or updates a CMDB record when it detects a running instance of PostgreSQL on UNIX systems.

Credentials and other prerequisites

These credentials are required:

For both Discovery and Service Mapping, see Service Mapping commands requiring a privileged user for a list of the commands that require elevated rights to discover and map Unix-based hosts in your organization.

The user must have root-level access to the database to access the postgresql.conf file.
Warning: DO NOT switch from probes to patterns if you are already running Discovery with probes, and your CMDB is already populated. If you do so, it is possible that the pattern Discovery process does not synchronize on the same values that the probe Discovery process does. This could result in duplicate CIs in your CMDB.

Classifiers, patterns, and probes

Classifier Trigger probes
PostgreSQL Instance
  • PostgreSQL - Configuration (add the must_sudo parameter to this probe)
  • PostgreSQL - Version
