Get-DbaReplSubscription

Synopsis

Retrieves SQL Server replication subscription details for publications across instances.

Description

Retrieves detailed information about replication subscriptions, showing which subscriber instances are receiving data from publications. This is essential for monitoring replication topology, troubleshooting subscription issues, and auditing data distribution across your SQL Server environment. You can filter results by database, publication name, subscriber instance, subscription database, or subscription type (Push/Pull) to focus on specific replication relationships.

Required Parameters

-SqlInstance

The target SQL Server instance or instances.

Optional Parameters

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.

-Database

Specifies which publication databases to include when retrieving subscriptions. Accepts multiple database names and wildcards.
Use this to focus on subscriptions from specific databases instead of checking all replicated databases on the instance.

-PublicationName

Filters results to subscriptions from specific publications by name. Accepts multiple publication names.
Use this when you need to check subscription status for particular publications rather than all publications on the server.

-SubscriberName

Filters results to subscriptions where data is being delivered to specific subscriber instances. Accepts multiple instance names.
Use this to monitor subscription health and activity for particular subscriber servers in your replication topology.

-SubscriptionDatabase

Filters results to subscriptions where data is being delivered to specific databases on subscriber instances. Accepts multiple database names.
Use this to track how data flows to particular databases across your subscribers, especially when subscription databases have different names than source databases.

-Type

Filters results to subscriptions of a specific delivery method (Push or Pull). Push subscriptions are managed by the publisher, while Pull subscriptions are managed by the subscriber.
Use this to separate subscription management tasks or troubleshoot issues specific to push or pull delivery mechanisms.

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with “sea of red” exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this “nice by default” feature off and enables you to catch exceptions with your own try/catch.
