Extended Transactions, which are transactions that span more than one monitored service/domain/device, are being tracked in a non-intrusive way over HTTP protocol. This correlation is defined by means of a global transaction ID.

Examples of extended transactions include:

A DMZ gateway relays a request into the LAN internal gateway. The request transcends two machines and would have consists of two separate transactions.
With the Extended Transaction, you can treat this operation as a single one.
An extended transaction may span domains inside a single gateway or across several gateways.

The following information is available for each extended transaction:

Column	Description
Service Name	The service the first transaction ran on
Operation/URI	The operation’s name for this first transaction or URI
Time	Timestamp for the first transaction.
Device Name	The device this first transaction ran on
Domain	The domain this first transaction ran on
Status	The status for the first transaction. The possible values are OK ERROR
Error Message	When the extended transaction completed in an error state, this column will hold the error message
Client IP	The client IP of the machine (or load balancer) where this transaction started.
Steps	Indicates the number of transactions that are part of the extended transaction
Gl. Trans. ID	Correlation ID between transactions across services/domains/devices
Elapsed (ms)	The number of milliseconds the extended transaction spanned.

Click the icon to the left of an extended transaction to open a panel with extra information relating the single transactions comprising it:

Column	Description
Service Name	The service this transaction ran on.
Time	Timestamp for the transaction.
Device Name	The device this transaction ran on
Domain	The domain the transaction ran on
Status	The status for this transaction. The possible values are: OK ERROR
Error Message	If the transaction ended in an error state, this column will hold the error message received. If the error message is too long, it will be abbreviated, with an ellipsis at the end. Hovering over a abbreviated message will display the full message in a pop-up
Transaction Id	The Transaction id. Click on the transaction id to open a single transaction view for this transaction
Elapsed (ms)	Total elapsed time, the number of milliseconds the transaction took.
Network Elapsed (ms)	Network elapsed time
Device Elapsed (ms)	DataPower processing elapsed time
Back-End Elapsed (ms)	Back-End processing elapsed time

Limitations
