Barman Servers Table

Overview

This dashboard contains a table that has all the monitored Barman servers. Each Barman server is expandable. When expanded, all the monitored PostgreSQL servers being backed up are displayed along with relevant information and current alarms.

Data

• Host: The Barman host being monitored which contains one or more PostgreSQL servers being backed up.
• Version: The Barman server version number.
• Availability: Status indicating if the Barman server is available.
• Overall Status: An aggregate status of the PostgreSQL servers being backed up by Barman.
• Name: The Barman special name or identifier for a given PostgreSQL server. Should be identical to the value in the Barman server configuration files.
• PostgreSQL Instance: The PostgreSQL host or IP that is being backed up by Barman.
• Active: Indicator if the server is active and being backed up by Barman.
• Passive Node: True or False indicator. A backup server that is connected to a Barman installation rather than a PostgreSQL server is considered a Passive Node; this is used for geographical redundancy.
• Minimum Redundancy: This column indicates if the minimum redundancy requirements are currently met for a PostgreSQL server.
• No. of Available Backups: The current number of available backups for a given PostgreSQL server on the Barman host.
• PostgreSQL Agent Status: Icon that indicates if the PostgreSQL server has an agent currently collecting data.
• Last Updated (PostgreSQL Admin only): Date that shows the last time the topology object was updated. This is useful in finding stale topology objects.
• Delete (PostgreSQL Admin only): Icon indicating if the topology object should be deleted. A pop-up with a prompt is displayed to confirm the deletion. Important: Deleting a topology object will delete any historical data, so do it cautiously.

Flows

• Click on the Barman Host column redirect to the Host Monitor dashboard.
• Click on the PostgreSQL Instance column to redirect either to the PostgreSQL Overview dashboard or to the Agent Status dashboard, depending on whether the given PostgreSQL server has a monitoring agent configured or not.
• Click on the Name, Active, Passive Node, or Min. Redundancy columns to redirect to the Barman PostgreSQL Server Overview page.
• Click on No. Of Available Backups to redirect to the Backups page.
• Deleting stale topology Objects (Admin Only): Only users with the PostgreSQL Administrator role can see this option in the table customizer. If old or incorrectly configured topology objects remain in the FMS, they may clutter the Barman server’s table until purged. To delete stale topology objects, click on the delete column. You can verify if a topology object is stale by checking the Last Updated date.
