You can optimize the Puppet Enterprise (PE) databases to improve performance. For database maintenance, we recommend using the pe_databases module.

Databases in Puppet Enterprise

PE uses PostgreSQL as the backend for its databases. Use the native tools in PostgreSQL to perform database exports and imports.

The PE PostgreSQL database includes the following databases:

Database Description
pe-activity Activity data from the Classifier, including user, nodes, and time of activity.
pe-classifier Classification data, all node group information.
pe-puppetdb PuppetDB data, including exported resources, catalogs, facts, and reports.
pe-rbac Role-based access control data, including users, permissions, and AD/LDAP info.
pe-orchestrator Orchestrator data, including user, node, and result details about job runs.

List all database names

Use these instructions to list all database names.

To generate a list of database names:

  1. Assume the pe-postgres user:
    sudo su - pe-postgres -s /bin/bash
  2. Open the PostgreSQL command-line:
    /opt/puppetlabs/server/bin/psql
  3. List the databases:
    \l
  4. Exit the PostgreSQL command line:
    \q
  5. Log out of the pe-postgres user:
    logout
