Why am I getting the "No time format was found on your conf file" error?

GoAccess does not have a default date and time formats for the log file. If you run "goaccess" command with default options, you will get this error:

fyicenter$ goaccess access_log -o report.html

 [SETTING UP STORAGE access_log] {0} @ {0/s}
GoAccess - version 1.5.6 - Apr  3 2022 21:52:23
Config file: /etc/goaccess/goaccess.conf

Fatal error has occurred
Error occurred at: src/parser.c - parse_log - 2060
No time format was found on your conf file.

There are two ways to resolve this error:

1. Use the "--log-format" option to specify the log file format, which includs the time format:

fyicenter$ goaccess access_log -o report.html --log-format=COMBINED 

2. Update the configuration file:

fyicenter$ sudo vi /etc/goaccess/goaccess.conf  

...
log-format COMBINED

fyicenter$ goaccess access_log -o report.html 

Do not use the "--time-format" and/or "--date-format" options, because the "--log-format" is still required:

fyicenter$ goaccess access_log -o report.html --time-format=%H:%M:%S
  No date format was found on your conf file.

fyicenter$ goaccess access_log -o report.html --date-format=%d/%b/%Y --time-format=%H:%M:%S 
  No log format was found on your conf file.

You can also use the "-c" option to set the format configuratin interactively:

fyicenter$ goaccess access_log -o report.html -c
