I'm adding more extensive logging to some server apps, and it would be
helpful to hear your opinions about formats.
I'm tempted to use the Extended Log Format commonly used by Apache and
many other server apps:
http://www.w3.org/TR/WD-logfile.html
I like the attraction of being able to say that my logs conform to a
well-regarded standard.
But on the flipside, I think that standard is crap. :)
Most of it's not bad, but the time part of it is horrible, with
timestamps expressed like:
[17/Jan/2015:00:06:48 -0500]
I'd prefer to use LC's internet date format:
Sat, 17 Jan 2015 12:01:35 -0800
Many log analysis workflows use sed or awk, which make it easy to work
with white space as delimiters. But since both time formats are
multi-word expressions, the brackets are needed to identify the
boundaries of the timestamp.
At a minimum I'm tempted to leave off the brackets, and to use LC's
internet date format instead of the format logs commonly use, which may
be slightly more compact but isn't automatically convertible into other
formats with LC's convert command, requiring extra processing when
looking for date ranges.
Going further, I'm inclined to consider tabs as delimiters rather than
spaces, so multi-word values like the timestamp and conceivably others
can be quickly identified as a single chunk.
Right now most of the log analysis done with these apps is done in other
LiveCode-based tools, so it would seem the choice is easily in favor of
a custom format optimized for parsing and sorting in LC.
But in all fairness, it's usually a good move to adopt common standards
whenever possible, even at some cost to efficiency, since it allows the
possibility of interoperability with other tools down the road if needed.
What would you do?
