show aggregated message

Syntax

show aggregated message [ {all | msgs} ]

Parameters

Description

This command prints the specified aggregated messages, which is useful when debugging parallel applications.

The root debugger collects the outputs from the leaf debuggers and presents you with an aggregated output. In most cases, this aggregation works fine, but it can be an impediment if you want to know the exact output from certain leaf debuggers. To remedy this, the debugger assigns a unique number, called a message ID, to each aggregated message and saves the message in the message ID list.

If you specify a list of message IDs, the debugger displays the aggregated messages with these IDs.

If you specify all, IDB displays all the aggregated messages in the list.

If you specify nothing, the debugger shows the most recently added message.
