Log analyzer for nginx [closed]
You can use goaccess to analyze your web logs and get a summary of hits, unique IPs, top static files, top 404s, different status codes and more. It displays a first top-level summary of information and then lets you drill down each main chapter interactively. You feed it a logfile or a pipe and it's very fast.
I discovered it here on SF and it has since changed my way of looking at webserver logs: I tend to do opportunistic, problem-driven log analysis and was dissatisfied with analog, awstats and webalizer.
If you are willing to get your hand dirty I would advise you to use Logstash + ElasticSearch + Kibana.
It can do much more than what you ask, but it can do what you ask well, and you will have a true inferface to actually browse your logs to understand what is - or has been - going on.
This is Kibana demo website
This is a blog post that shows how it has been setup to analyze Apache Tomcat with this platform, you can simply adapt it to your needs : http://spredzy.wordpress.com/2013/03/02/monitor-your-cluster-of-tomcat-applications-with-logstash-and-kibana/
I had to use awstats with Nginx this week and you don't have to use cgi-bin necessarily. Awstats comes with the awstats_buildstaticpages.pl script that will generate static html files which you can then serve with Nginx. With a cron job I update the html files regularly.
/usr/share/doc/awstats/examples/awstats_updateall.pl now -awstatsprog=/usr/lib/cgi-bin/awstats.pl
/usr/share/awstats/tools/awstats_buildstaticpages.pl -update -config=domain.com -dir=/path/to/save/html/files awstatsprog=/usr/lib/cgi-bin/awstats.pl
(Depending on your OS the paths may differ a little but you will be able to find the scripts)
In order to prevent data loss during log rotation you can add this line to your awstats.domain.com.conf file:
LogFile="/usr/share/awstats/tools/logresolvemerge.pl /path/to/log/access.domain.tld.log /path/to/log/access.domain.tld.log.1 |"
The script will merge the last 2 logs whenever you fetch the log for updating your data. Or you can add a pre-logrotate hook on Nginx like they do here: http://www.bytetouch.com/blog/system-administration/how-to-awstats-installation-and-configuration-on-debian/
