Ask HN: How do you monitor server logs

How do you do it ? For example, if you have apache running on Ubuntu, you can go into command line and do a grep or even tail -f /var/log/apache2/access.log

What simple tools/services are out there to monitor stuff like this ? Realtime is an added-bonus.

There are many ways, icinga and check_mk have logwatch module to alert on messages matching a regex.

Log aggregation can be done with file beat (logstash) with kibana as frontend. Then there is sentry (python) for logs.

this looks legit, what is your experience like with it so far?
