Just a quick tip:
The current version of the Tivoli Log File Agent is 220.127.116.11. However, it is packaged with the 18.104.22.168 version of the ITM libraries (known as the TEMA). This means that it will work with any version of the ITM infrastructure from 22.214.171.124 on up. You do not have to be on 6.2.3+ of ITM in order to use it.
I know this causes some understandable confusion, so wanted to post this clarification.
Some future release will ultimately have to move forward and require the newer ITM libraries, but that time has not yet come.
Of course, if you are using the agent only with OMNIbus, and do not have an ITM infrastructure, then you don't need to care what version of the libraries are included.
