Synopsis

Displays replication latency for all transactional publications for a server or database.

Description

Creates tracer tokens to determine latency between the publisher/distributor and the distributor/subscriber for all transactional publications for a server, database, or publication.

All replication commands need SQL Server Management Studio installed and are therefore currently not supported. Have a look at this issue to get more information: https://github.com/dataplat/dbatools/issues/7428

Required Parameters

-SqlInstance

The target SQL Server instance or instances.

Optional Parameters

-Database

The database(s) to process. If unspecified, all databases will be processed.

-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.

-PublicationName

The publication(s) to process. If unspecified, all publications will be processed.

-TimeToLive

How long, in seconds, to wait for a tracer token to complete its journey from the publisher to the subscriber. If unspecified, all tracer tokens will take as long as they need to process results.

-RetainToken

Retains the tracer tokens created for each publication. If unspecified, all tracer tokens created will be discarded.

-DisplayTokenHistory

Displays all tracer tokens in each publication. If unspecified, the current tracer token created will be only token displayed.

-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.
