What is the supported format of apache logs?

We support logs that follow the Access combined format.

 This is an example of a log line:

109.65.122.142 - - [10/Nov/2015:07:06:59 +0000] "POST /kibana/elasticsearch/_msearch?timeout=30000&ignore_unavailable=true&preference=1447070343481 HTTP/1.1" 200 8352 "https://app.logz.io/kibana/index.html" "Mozilla/5.0 (X11; Linux armv7l) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/45.0.2454.101 Chrome/45.0.2454.101 Safari/537.36" 0.465 

 In order to enable these logs on the Apache server, you can use the following configuration (and you can read more here):

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined
CustomLog log/access_log combined
