Time alignments between system clocks in a cross-process trace often are not synchronized. Cross-process traces align the trace with the front-end trace that invoked it.
Note: Usually traces are displayed in order based on the system clock where they originated. All back-end traces sourced from the same CA APM Cross-Enterprise agent can be synchronized properly relative to each other but not the correlated front-end transaction.
CTG and web services calls are not displayed relative to their actual synchronization with the front end calling transaction. The associated events for these back-end traces are group together, enlarged, and aligned to the left in the Trace View.
MQ calls are asynchronous and occur after the front-end application terminates. The delay is shown regardless of discrepancies introduced by clock synchronization. In the Trace View these events are not aligned, enlarged, or grouped together.
The IMS transaction trace timestamp starts when the transaction is placed on the input queue.
When searching for the corresponding IMS SMF record for a transaction trace always use the Unit of Work ID from the trace and the command:
IMSTLOG UOW <value_of_Unit_of_Work_ID>;
Do not attempt to use the timestamp from the IMS transaction trace in the Workstation to find the corresponding IMS SMF record in CA SYSVIEW. The IMS SMF record time shows process start time instead. For transactions that stay on the input queue for a long time these two values can differ significantly.
