Hello, I would ask you if it is posible to write filter which remove every duplicate lines from one source usage as: log ( source; filter(duplicate); destination) parameters: number of lines which can be betwen the same line (this is becouse some messages are repeated in a block of lines) time period which will defined when the counter must be reset (before that counter will be send) and next line will be again the first one counter - to count number of droped lines and show this value every time period - like solaris syslog do duplicate line means : 1 line: aaaaa bbbbbb 2 line: cccccc 3 line: aaaaa bbbbbb 4 line: cccccc ... line: aaaaa bbbbbb ... line: cccccc 9 line: ddddd lines 1,2,9 will pass to destination lines 3-8 will be removed (droped) in the past it was a filter - DEFAULT which did this job in a "some" way and I thing now it is nothing which can be usable any idea? with regards Peter STRAKA
