What real-time log analyzer can you suggest for Apache access and error logs?

There is a list of web analytics software on WikiPedia, but it would be great to hear opinions from people with experience without having to try all of them.

Please don't suggest Google Analytics or any other hosted/JavaScript analytics suites, already using them, GA is not real-time and it is missing some data that the logs show. For example 404 errors, script errors, the full query-string of the referral, IP addresses, visitor path through the website, etc ...

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.

    can this be turned into community-wiki? – Evgeny Nov 2 '10 at 16:07
  • Real time log analysis is waay different than real time JS-based tracking. The former is difficult to implement and doesn't scale across multiple instances, and the latter is what Google Analytics uses. If you're looking for a solid Apache logs analyzer, check out Angelfish. analytics.angelfishstats.com – Andrew C Mar 25 '16 at 19:02

    I disagree with the policy of banning all opinion based questions. In many cases an opinion is valuable information, especially if the writer has used more than one product. Rather than ban them, opinion based questions should be flagged as such, and answers held to a different standard. – Sherwood Botsford Nov 25 '16 at 14:19

I was using Urchin before I switched to Google Analyics. The Urchin Project no longer exists.

  • didn't know urchin could analyze logs -- but it can! this is great! – Evgeny Nov 2 '10 at 15:56

    only downside is that it costs a fortune :/ – Evgeny Nov 2 '10 at 15:58

    This is the new alternative to Urchin (open source!) piwik.org/log-analytics – NickT Oct 23 '13 at 2:21

GoAccess is a free text/curses based log analyzer similar to "top".

AWStats is a good open source solution.

Also see http://www.awstats.org and https://github.com/eldy/awstats

  • doesn't support nginx – Jürgen Paul Aug 20 '12 at 3:07

    AWStats supports Apache log format, and nginx can easily output in Apache log format, so... it does support nginx indirectly. – Tim Tisdall May 13 '15 at 13:58

Matomo (former Piwik) is a good choice (better than awstats, in my opinion)

This might seem like a bit of overkill, but Splunk offers web log analyzing and much, much more.

If you're looking for an offline analyzer, I quite like Sawmill:

https://www.sawmill.co.uk

It analyses all sorts of logs, including apache. Has a free trial period.

ChartBeat a very interesting service, it is actually much more than log analyst - more like a view of the buzz your blog creates, in real-time. Another tool that shows real-time Apache log streams I found, called A Live Log.
