Goaccess: Unhelpful error message if date/time/log format does not match

[ottok]

Hello!

I am experincing the error message:

GoAccess - version 1.0.2 - Jul  4 2016 19:44:08
Config file: /etc/goaccess.conf

Fatal error has occurred
Error occured at: src/goaccess.c - main - 1230
Nothing valid to process. Verify your date/time/log format.

The error message is unhelpful. I have no idea which of my formats is incorrect. I've tried changing them all to multiple variants, but I always get the same error message and I am clueless.

It would be nice if the error message would be a bit more exact, and give the user some hint where the parsing actually fails to narrow down what should be changed.

My log format:

example.com - - - [23/Oct/2016:06:28:01 +0300] "GET /wp-admin/admin-ajax.php?action=heartbeat HTTP/1.1" 200 59 "-" "speedometer/fal-test1" - 0.044
example.com - - - [23/Oct/2016:06:29:01 +0300] "GET /wp-admin/images/wordpress-logo.png HTTP/1.1" 200 2480 "-" "speedometer/fal-test2" - 0.000

My command:

 goaccess --log-format='%h %^ %^ %^ [%d:%t] "%r" %s %b "%R" "%u" %^ %T' --date-format='%d/%b/%Y' --time-format='%H:%M:%S %z' -f test.log

Thanks for pointing this out. This has been implemented - issue #264 addressed this. Feel free to build from development, otherwise, it will be pushed out soon in the upcoming version.

For your log, this is the output:

Token 'example.com' doesn't match specifier '%h'
Token 'example.com' doesn't match specifier '%h'

You will need a valid IPv4/6 for the %h part.

I just built from git master and it works nicely, thanks!

That's great! Stay tuned for the upcoming version, some nice changes are coming :)

also I tried
time-format %H:%M:%S\ %z

log-format %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"

Error:

@laurfx Try:

goaccess -f access.log --log-format=COMBINED

or

log-format %h %^[%d:%t %^] "%r" %s %b "%R" "%u"
date-format %d/%b/%Y
time-format %T

[laurfx]

After I read the documentation better I understand what you did in the last format.

It's working, thank you.

date-format %d/%b/%Y
