1. "A processing policy containing this action will only continue forward if the log
action can successfully send its payload to the destination given. If the action
cannot succeed in this manner, an error occurs.
This action also waits for the configured amount of time (in this case, the default
timeout value for the URL used) to receive a reply. If no reply is received, the
processing policy then continues to completion." (pg 172)
Does this mean that if a log message is unable to be sent, that the process is halted? I would rather miss a log entry - is this an optional setting somewhere?
2. "Event log messages cannot exceed 2 kilobytes (KB) in size. Messages that are larger than 2 KB are truncated." (pg 173)
2kb is rather small, and could potentially cause problems by truncating an XML message (making it not well-formed by cutting off the closing tags) - is there a possibility of sending an "alternative" message that contains less information if the desired message would be above 2kb? (yes, style sheets can be used to shorten the message, but is there any way for a style sheet to "know" the size of the message in order to only trim to the necessary amount?)
P.S. - I am running version 18.104.22.168, and this refers to version 3.8.2 - I have tested larger logs and the limit appears to be 1mb as opposed to 2kb, and that an invalid log target does not halt execution, but I would like to confirm that this is the normal operation and not just a bug or something that will change in future versions
Re: DataPower Transactional Logging details2013-02-18T17:16:51Z in response to SystemAdminJust to be clear, are you trying to log details of your B2B transactions? I can't speak to how well you'd be able to implement that using log targets, etc, but you can easily extract B2B transactions using the XML management interface. We have a service that polls our appliances every so often and retrieves all the B2B transactions since the last poll. Not exactly real-time but it works very well for our purposes.
Re: DataPower Transactional Logging details2013-02-19T09:55:13Z in response to SystemAdminOK that's exactly what we are doing. We just poll the XML Management Interface every 10-15 minutes for all the transactions since the last poll. The request format is as follows. The maximum number of transactions is 1000, so you may need to submit a few requests to retrieve all the transactions between polling intervals.
<?xml version="1.0" encoding="utf-8" ?>
<dp:request xmlns:dp="http://www.datapower.com/schemas/management" domain="YourDomain">
This is probably the simplest solution. If you needed your transactions at closer to real-time, I suppose you could hook something into the Document Routing Preprocessor stylesheet of your B2B Gateway and fire the transactions to an MQ queue/topic.

I know this was posted more than a year ago, but I am putting this together right now for my transaction logs.
We are new to the XB62 world, but for the most part it is pretty intuitive.
I have one XML Management Interface per XB62 but I have 2 domains on each one with a transaction log of their own.
I am having troubles getting my pole to work using the b2b-query-metadata.
Any advise ?
