Problems with the tomcat acess-logs

I need your help. I want to log the access on my Apache Tomcat webserver on SLES 12. He is running and he is logging normally. But when I visit the site, tomcat is writing 8 lines into the localhost_access_log.txt file. Like this:

10.XXX.XX.XXX - - [27/Jul/2016:08:28:29 +0200] "GET / HTTP/1.1" 200 11250 10.XXX.XX.XXX - - [27/Jul/2016:08:28:29 +0200] "GET /tomcat.css HTTP/1.1" 200 5576 10.XXX.XX.XXX - - [27/Jul/2016:08:28:29 +0200] "GET /tomcat.png HTTP/1.1" 200 5103 10.XXX.XX.XXX - - [27/Jul/2016:08:28:29 +0200] "GET /favicon.ico HTTP/1.1" 200 21630 10.XXX.XX.XXX - - [27/Jul/2016:08:28:29 +0200] "GET /bg-nav.png HTTP/1.1" 200 1401 10.XXX.XX.XXX - - [27/Jul/2016:08:28:29 +0200] "GET /asf-logo.png HTTP/1.1" 200 17811 10.XXX.XX.XXX - - [27/Jul/2016:08:28:29 +0200] "GET /bg-middle.png HTTP/1.1" 200 1918 10.XXX.XX.XXX - - [27/Jul/2016:08:28:29 +0200] "GET /bg-button.png HTTP/1.1" 200 713 10.XXX.XX.XXX - - [27/Jul/2016:08:28:29 +0200] "GET /bg-upper.png HTTP/1.1" 200 3103 10.XXX.XX.XXX - - [27/Jul/2016:08:28:29 +0200] "GET /favicon.ico HTTP/1.1" 206 21630 10.XXX.XX.XXX - - [27/Jul/2016:08:28:29 +0200] "GET /favicon.ico HTTP/1.1" 200 21630

The same when I logged in as an admin, then tomcat write 5 lines.

10.XXX.XX.XXX - - [27/Jul/2016:10:37:01 +0200] "GET /manager/status HTTP/1.1" 401 2473 10.XXX.XX.XXX - admin [27/Jul/2016:10:37:02 +0200] "GET /manager/status HTTP/1.1" 200 7010 10.XXX.XX.XXX - - [27/Jul/2016:10:37:03 +0200] "GET /manager/images/tomcat.gif HTTP/1.1" 200 2066 10.XXX.XX.XXX - - [27/Jul/2016:10:37:03 +0200] "GET /manager/images/asf-logo.gif HTTP/1.1" 200 7279 10.XXX.XX.XXX - - [27/Jul/2016:10:37:03 +0200] "GET /favicon.ico HTTP/1.1" 200 21630

Now my question: It’s possible, that tomcat only write one line per access? Or that tomcat write the log in a per-sonal format? Because I want to analyses the access-logs with graylog2 and grayog has some problem with this.

Yours sincerely
