Thank you for your reply, you're the only person who read my post and<br>
didn't somehow think I was saying "remove the UUIDs" ! ;-)<br>
<br>
Regarding : "Consistency is good, but certain functionality cannot be<br>
<span class="">provided if every single line has exactly the same format."<br>
<br>
</span>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<br>
still call that a whim, especially as there is no clear documentation<br>
on the matter either !!!!<br>
<br>
Even the Freeswitch docs don't know what's what ... " The log file<br>
will contain log lines in this general format: YYYY-MM-DD hh:mm:ss<br>
[LEVEL] source_file_name:line_number function_name() <log data>" ,<br>
that statement is not true. That's not the general format. its not<br>
even the dominant format, infact in my logs, lines that start<br>
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>
