Ok....I've now had time to make progress with this little project. I've added
my code ( a mixture of yours & mine ) and inserted it in your original
post below. You'll need to make some changes given we are addressing
different apache2 logs. That's an area where I got caught out. I forgot
that you were accessing a different log file & it all kept going
pear-shaped until the little light globe went on

Plus I've created a minor problem by naming my main library
"Calibre Library" ; note the space. I could not get this working at
all until I realised this space was probably the culprit. It was just
a matter of creating a link to it and referencing the link in the
code. sqlite3 worked fine then. A lesson learned.

So just substitute your original code for mine if you're so inclined.
I've commented the areas.

As you can see it's pretty much your code modified & added to

helped a lot!

...... Yes...me too

Sample output...

23-Feb-2016 userA 192.168.1.1 ---Internal IP address.----
Title Author Given-name Surname

23-Feb-2016 userB 58.nnn.nn.nn Concord New South Wales AU 2137 -33.8429,151.1107
Title Author Given-name Surname

Yes...I know....GPS coordinates are a little over the top but it's
interesting that you can do this kind of stuff

Any questions, just yell

Cheers
