Event Directions
Helps you and your business filter Log Events so you can distinguish the same message before and after port/workflow processing
EventDirections is an optional field (number) part of Log Events and qualifies the direction for a Log Event and can be used to create fine-tuned Self Service Log Views for your business.
High level design or implementation specific details?
Whenever you have a messaging process it usually has many steps where some are internal and some are external, examples can be:
Message from A to B - Business perspective
Imagine you work at the financial department, you may only be interested in the result, not all the information that stems from generating the final result.
- Message before decryption
- Message after decryption
- Message before encryption
- Message after encryption
- Message batch before a split
- Messages After the split
- Flat file before being translated to an XML (for example BizTalk, IBM IIB and other brokers who use flat file schemas on a Receive port)
- Flat file after being translated from an XML (for example BizTalk, IBM IIB and other brokers who use flat file schemas on a Send port)
- Workflow / Orchestration inside a loop generating new messages
There are countless scenarios like this. The point is the Event Direction property is used to provide the Log Event being logged on an Endpoint location semantics, like before port, after port, inside workflow, inside process and so on.
How do I use the Event Directions in a Log View?
From Log Views your business can search and group Log Events by the selected Event Direction.
Event Direction being used from within a Log View.
This feature makes it possible to hide internal events that your business may not be interested in. They might only be interested in what came in, or what went out (the net result), not all the nitty-gritty internal details. On the opposite side, you might be a developer who wants to see every piece of the process.

Combined Event Directions
From Log Views your business can search and group Log Events by the selected Event Direction using Combinations of 1 or more Event Directions.
This means you may want to only see (allow business) messages before processing and after processing for a given workflow, for example, lines 1 and 5.
Valid combinations are as detailed below:

| 3+6 | Response | Filter on ALL messages with any type of Response direction |
| 1+2+3+4+5+6 | External | Filter on ALL messages going in from external or going out to external system. For BizTalk this means before receive port and after send port |
| 7+8 | Internal | Filter on ALL internal messages. For BizTalk this means after receive port and before send port |
| 9+10 | Process | Filter on ALL messages for a Process direction. For BizTalk this is all events related with an orchestration |
