Chapter 43. Control Center
PPEM supports the control center that you can use for monitoring the state of instances and troubleshooting them if required.
To view the state of instances using control center, in the navigation panel, go to Monitoring → Operation control center.
The control center with the following elements of the web application interface will be displayed:
List of all instances (the left block)
Instance tiles (upper block)
Instance performance indicators (lower block)
List of All Instances #
The list of installed instances is displayed in the left block. The color of the dot located next to each instance name indicates the instance status:
Green (
): The instance is operating normally.
Red (
): An error occurred during instance
operation.
Gray (
): Failed to determine the instance state.
Instance Tiles #
Installed instances are displayed as tiles in the upper block. Each tile displays the instance uptime, name, and the server where it is installed.
The tile color indicates the instance status. The correlation between the instance status and tile color is the same as for the dots in the list of all instances.
You can perform the following actions using an instance tile:
Go to instance management by clicking
→
Go to instance.
Start the psql terminal of an instance by clicking
→
Open PSQL terminal.
Start a stopped instance by clicking
→
Start instance.
Instance Performance Indicators #
The lower block allows monitoring key instance performance indicators using graphs based on metrics collected by pgpro-otel-collector. For the graphs to work properly, you must first install and configure logging and monitoring tools.
To view a graph, in the upper block click the instance tile, and then in the top-right corner of the lower block, select the graph.
For a description of the graphs, refer to Section 44.1.
You can perform the following actions using the icons in the top-right corner of graphs:
To display the specified period covered by a graph, click Select interval, and then select the period on the graph.
To reset the period, click Reset.
To download a graph in the PNG or CSV format, click Download .png or Download .csv.
