It would be nice to have a log filtering tool, which can help to extract / highlight log statements in huge log files.

An idea could be to have a SQL like language in order to limit the number of lines as much as possible

SELECT * FROM server.log WHERE CATEGORY = 'org.jboss.as' AND SEVERITY IN {FATAL OR ERROR OR WARN} AND TIMESTAMP >= '12:42:00,000' AND CONTENT CONTAINS 'Something went wrong'

Having functions to select all / a defined number of lines after each hit, between timestamps, and so on would be good.
