If you use an external monitoring application that can tag transaction headers, BMC Application Diagnostics can provide a detailed view of specially tagged transactions. If your external application can add a tag to specific transactions, you can use that tag to persist the specific transactions, regardless of sampling or threshold configuration.


To prevent adverse system performance, use tagging on a very limited number of transactions.

This topic presents the supported tagging mechanisms.

Tags to persist transactions

You can tag multiple incoming HTTP requests to persist the transaction. This is useful when you want to see diagnostics data for transactions that occur infrequently. For example, you can examine diagnostics data for transactions tagging by another monitoring application.

For details about tagging HTTP headers, see Persistence of tagged transactions.

Tags to persist transactions and link to details

You can use integration tags for the requests with a specified header, request parameter, or cookie, and then link directly to the trace details in BMC Application Diagnostics form the external application.

For details about tagging and linking from external systems, see Persistence of tagged transactions.
