omitted.<br>
<br>
I'm not sure how you can call this random and inconsistent.<br>
<br>
Now you may be confused by additional logging that may be enabled such as<br>
the logging from maybe libsofia, or one of the other many libs that<br>
FreeSWITCH uses. FreeSWITCH has no control over underlying library logging<br>
formats.<br>
An example of this is if you have sofia global siptrace enabled. The<br>
formatting there is directly from the library and we have no control over it<br>
other than to enabled or disable it.<br>
<br>
This is common with libraries not just for FreeSWITCH but many other open<br>
source projects...<br>
<br>
As with pretty much everything in FreeSWITCH it's a module, don't like the<br>
logging modules that are there now you are welcome and encouraged to create<br>
your own, and patches are accepted on a regular basis.<br>
<br>
At this time I will consider this thread closed.<br>

Thank you for your reply, you're the only person who read my post and didn't<br>
somehow think I was saying "remove the UUIDs" ! ;-)<br>
<br>
Regarding : "Consistency is good, but certain functionality cannot be<br>
provided if every single line has exactly the same format."<br>
<br>
Yes, but the inconsistency makes it painful, verging on impossible, to<br>
correctly integrate with various log parsing systems, whether Splunk,<br>
Logstash or otherwise.<br>
<br>
<br>
If the devs have some personal preference for one format here, another<br>
format there, and something else over there, I would unfortunatley still<br>
call that a whim, especially as there is no clear documentation on the<br>
matter either !!!!<br>
<br>
Even the Freeswitch docs don't know what's what ... " The log file will<br>
contain log lines in this general format: YYYY-MM-DD hh:mm:ss [LEVEL]<br>
source_file_name:line_number function_name() <log data>" , that statement is<br>
not true. That's not the general format. its not even the dominant format,<br>
infact in my logs, lines that start YYYY-MM-DD are a rarity !<br>
<br>
<br>
I have not come accross any other product (either closed or open<br>
source) that has the quite same amount of randomness in the way it<br>
logs. That is what I find so frustrating.<br>
