Question
What do entries in the Apache logs mean?
Answer
Check the logs as described below and reference the format chart.
cd /m1/shared/apache2/conf/modules.conf/- view
mod_log_config.conf - Look at
LogFormatentries - examples:
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %b" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent
4. Interpret the format
| %h | Remote host |
| %l | Remote logname (from identd, if supplied). This will return a dash unless mod_ident is present and IdentityCheck is set On. |
| %u | Remote user (from auth; may be bogus if return status (%s) is 401) |
| %t | Time the request was received (standard english format) |
| "%r" | First line of request |
| %s | Status. For requests that got internally redirected, this is the status of the *original* request --- %>s for the last. |
| %b | Size of response in bytes, excluding HTTP headers. In CLF format, i.e. a '-' rather than a 0 when no bytes are sent. |
| %{Referer} | Referer is the page that linked to this URL |
| \"%{User-Agent}i" | User-agent is the browser identification string. |
