Enable "CONNECTION_THROTTLING" Parameter for PostgreSQL Servers

01 Sign in to Azure Management Console.

02 Navigate to All resources blade at https://portal.azure.com/#blade/HubsExtension/BrowseAll to access all your Microsoft Azure resources.

03 From the Type filter box, select Azure Database for PostgreSQL server to list only the PostgreSQL servers created in your Azure account.

04 Click on the name of the PostgreSQL database server that you want to examine.

05 In the navigation panel, under Settings, select Server parameters to access the configuration parameters available for the selected PostgreSQL server.

06 On Server parameters page, find the connection_throttling parameter using the Search to filter items search box. Once the parameter is found, check its configuration value, available within the VALUE column. If the parameter value is set to OFF, the "connection_throttling" server parameter is not enabled for the selected Azure PostgreSQL database server.

07 Repeat steps no. 4 – 6 for each PostgreSQL database server provisioned in the current Azure subscription.

08 Repeat steps no. 3 – 7 for each subscription created in your Microsoft Azure cloud account.

01 Run postgres server list command (Windows/macOS/Linux) using custom query filters to list the names of all PostgreSQL database servers (and the name of their associated resource groups) available in the current Azure cloud subscription:

az postgres server list
	--output table
	--query '[*].{name:name, resourceGroup:resourceGroup}'

02 The command output should return a table with requested PostgreSQL server information:

Name                ResourceGroup
------------------  ------------------------------
cc-psql-db-server   cloud-shell-storage-westeurope

03 Run postgres server configuration show command (Windows/macOS/Linux) using the name of the Azure PostgreSQL server that you want to examine and its associated resource group as identifier parameters, and custom query filters, to obtain the "connection_throttling" parameter value for the selected database server:

az postgres server configuration show
	--server-name "cc-psql-db-server"
	--resource-group "cloud-shell-storage-westeurope"
	--name connection_throttling
	--query 'value'

04 The command output should return the requested configuration value ("ON" for enabled, "OFF" for disabled):

"OFF"

05 Repeat step no. 3 and 4 for each Microsoft Azure PostgreSQL server available in the selected subscription.

06 Repeat steps no. 1 – 5 for each subscription available within your Microsoft Azure cloud account.

01 Sign in to Azure Management Console.

02 Navigate to All resources blade at https://portal.azure.com/#blade/HubsExtension/BrowseAll to access all your Microsoft Azure resources.

03 From the Type filter box, select Azure Database for PostgreSQL server to list only the PostgreSQL servers provisioned in your Azure account.

04 Click on the name of the PostgreSQL server that you want to reconfigure (see Audit section part I to identify the right database server).

05 In the navigation panel, under Settings, select Server parameters to access the configuration parameters for the selected PostgreSQL database server.

06 On Server parameters page, find the connection_throttling parameter using the Search to filter items search box.

07 Once the connection_throttling server parameter is found, enable it by selecting ON from the toggle configuration button, available in the VALUE column.

08 Click Save to apply the configuration changes.

09 Repeat steps no. 4 – 8 for each PostgreSQL database server available within the selected subscription.

10 Repeat steps no. 3 – 8 for each subscription created in your Microsoft Azure cloud account.

01 Run postgres server configuration set command (Windows/macOS/Linux) using the name of the PostgreSQL server that you want to reconfigure as identifier parameter (see Audit section part II to identify the right database resource) to enable "connection_throttling" parameter for the selected Microsoft Azure PostgreSQL database server:

az postgres server configuration set
	--server-name "cc-psql-db-server"
	--resource-group "cloud-shell-storage-westeurope"
	--name connection_throttling
	--value on

02 The command output should return the metadata for the reconfigured server parameter:

{
  "allowedValues": "on,off",
  "dataType": "Boolean",
  "defaultValue": "on",
  "description": "Enables temporary connection throttling per IP for too many invalid password login failures.",
  "id": "/subscriptions/abcd1234-abcd-1234-abcd-abcd1234abcd/resourceGroups/cloud-shell-storage-westeurope/providers/Microsoft.DBforPostgreSQL/servers/cc-psql-db-server/configurations/connection_throttling",
  "name": "connection_throttling",
  "resourceGroup": "cloud-shell-storage-westeurope",
  "source": "user-override",
  "type": "Microsoft.DBforPostgreSQL/servers/configurations",
  "value": "on"
}

03 Repeat step no. 1 and 2 for each PostgreSQL database server currently available in the selected subscription.

04 Repeat steps no. 1 – 3 for each subscription created within your Microsoft Azure cloud account.
