Trying to filter logs in the inputs- not working

[saravanababumr]

Trying to filter the backdated logs which has appeared from till yesterday and start with recent logs

[monitor:///dir1/app/app1/jboss/server/default/log/localhost_access_log.*]
index = index_filter_local
_blacklist = (localhost_access_log.2011-11-30.log|localhost_access_log.2011-12-[01-11])

I tried to filter using the _blacklist but this is not working , i don't see the indexing itself is happening

Have you tried using the "ignoreOlderThan" property in your monitor stanza ?

[monitor:///dir1/app/app1/jboss/server/default/log/localhost_access_log.*] 
index = index_filter_local
ignoreOlderThan = 1d
