When you click a transaction’s ID in the transactions list, DPOD loads the full details of the transaction into the information window.

This view provides a plethora of information about the single transaction.

Transaction Details Panel

The panel at the top of the window displays various details about the transaction, such as time, status, device, domain, API Name, catalog, etc.

Transaction Analysis Panel

Error analysis

Displays a summary of all errors found by DPOD for this transaction.

Elapsed Time 

A breakdown of the transaction’s elapsed time between network, gateway processing and Back-End processing.
This analysis lets you view latency data pertaining to the transaction, and potentially identify network congestion or issues.

Payload Size

Displays the request and response size.

Memory

Memory consumption graphs for the transaction, across the transaction lifetime and state changes.
The memory graph is designed to display the differential memory consumption between processing policy actions in a processing rule.

The purpose is to assist the user in troubleshooting high memory consumption by one or more processing actions (for example when using inefficient XSLT).
The graph is built based on the DataPower “memory-report” records.
In some cases the memory value reported at the beginning of a transaction is higher than the following memory report leading to a negative value.

To investigate the service’s total memory usage please navigate to Dashboards -> Resources -> Service Memory.
The memory graph display the differential memory value in KB.

Policy Graph

Green nodes represent user policies and their latency, hover over the latency node to view more details.
Blue nodes represent the API Framework latency.
Pre/Post processing polices (DataPower API Gateway only) will appear with a Blue border.
Click on a user policy or on a pre/post policy to open the Policy Details Window.

Policy Details Window

The top part of the window shows the policy graph, you can focus on any user policy by clicking it.
The middle part shows general details about the policy, such as the policy name, type and the execution time in ms.
The lower part shows a list of side calls made by this policy. and a list of context variables and their values (if a policy variables capture was active during the execution of this transaction)
If a policy variables capture was active, but no data is showing in the "Context variables" table - wait a few seconds and refresh the page, it may take up to 2 minutes for the data to appear.

Keyboard shortcuts - 
Left or Right arrows - Previous / Next policy
Space - Wrap the policy variables values text.
Escape - Close the window.

Raw Messages Tab

This widget lists the raw messages that make up the single transaction viewed (up to 2000 messages). 

Tracking the raw messages making up transactions in error may provide insights into the causes of failures.

Tracking the raw messages making up successful transactions may provide insights into slow components or unnecessary steps.

The information is displayed in a table.

Payload Tab

When WS-M recording is switched on, the Payload pane of the table will contain payload information for the messages displayed.
The payload is shown for the front end, for both the request and response phases. 

Extended Latency Tab

Detailed latency information for both the request and response phases.

Side Calls

The side calls tab shows both side calls that were made by user policies and internal side calls (such as calls to API-C Analytics).

Correlated Transactions Tab

The Correlated Transactions Tab (Appears only if the user has appropriate permissions), shows all the transactions with the same Global Transaction ID, both Gateway transactions and API-C transactions are shown.
The transactions are sorted by their start time, where the first transaction that run appears on top..

The Trans. ID column displays the transaction ID of the correlated transaction, or "Current" for the current transaction in view. Click the Transaction ID to navigate to the Single Transaction Page of that transaction.
The link will appear only if the user has appropriate permissions to view that particular transaction.

The Service/API column displays the Gateway Service name, or the API Name+API Version.

The Status column displays the transaction status, as shown in the Single Transaction page.

The Message column displays the error message analysis, as shown in the Single Transaction Page. (see "Error Analysis" previously on this page)

Clicking on the Raw Errors links (appears only if the transaction did have any errors, and only if the user has appropriate permissions) will open a window with the all the transactions' error messages, note that the existence of error messages doesn't necessarily mean that the transaction failed.
