Free Web Based Server Log Viewer/Monitor [closed]
Solution 1:
Splunk is excellent and free if you are generating under 500Mb of logs per day
Solution 2:
Well, im currently using Nagios
There is not much that you cannot do with the software and it is all free! There are plugins for monitoring all kinds of logs. Its a bit of a pain to setup but fantastic once its all working. If you cannot find a plugin, you can write your own quite easily.
Ive also just setup Awstats, which is fantastic for monitoring IIS logs, the website says it supports Apache logs, not tested though
