60.1. Viewing Cluster Parameters #
To view the cluster configuration parameters:
In the navigation panel, go to Infrastructure → Clusters.
Click the name of the cluster.
In the navigation panel, go to Parameters.
The page displays the configuration parameters of the primary/leader node. Parameters are grouped by categories. If any standby/follower node has parameter values that differ from the primary/leader, these differences are also displayed.
The parameter table includes the following columns:
Parameter: The name and description of the parameter.
This column also displays the parameter application status and errors, if they occurred.
To open a full description of the parameter in the official Postgres Pro documentation, click its name.
Scope: Defines how the parameter value is applied to cluster nodes. If all nodes have the same value, the All cluster nodes toggle is enabled. If values differ across nodes, the toggle is disabled, and the node list shows the value for each individual node.
To set different values for specific nodes, disable the toggle. The node list becomes available, with the primary/leader node at the top and the remaining nodes listed below.
When the toggle is disabled, the value that was previously set for the entire cluster is used as the default for each node.
Value.
Default value.
Source: The source of the parameter value based on the
sourcecolumn of thepg_settingsview.Possible values inсlude (but are not limited to):
default: This is the default parameter value.
configuration file: The parameter value is specified in the configuration file.
override: The parameter value is overridden at the initialization stage.
To view the parameters of a specific node, select it from the Node drop-down list. The page will be updated to show only the parameters of the selected node.
You can also filter the parameter list by:
Category: From the drop-down list above the parameter table, select the category name.
Name: In the top-right corner of the page, enter a full or partial parameter name in the search bar.
Default values: In the top-right corner of the page, enable or disable the Hide parameters with default values toggle.
