Hello list, I've just setup a centralized syslog-ng server with mysql Remote clients work well but I'v got a little problem with a filter ... On each client I've got snmp daemon running and nagios network manager server polling clients ... My problem is that each time my nagios NMS connect it to a client it appears this line in daemon.info client log "Oct 10 03:15:48 vlanrouter1 snmpd[1868]: Connection from 192.168.0.12 " I would like to filter this line to exclude it from the remote log ... So I 've added this filter filter f_not_daemon_info { (not facility(daemon) and not level(info)); }; but not works and all "daemon" and all "info" levels are removed not just "daemon.info" I've search to remove this log from snmp daemon directly but seems to be a bug on my snmpd release ... I hope that someone have got the solution Regards Sebastien
