Guys Playing around with ng 2 and I started looking at the match filter again. Simple question that I cannot find an answer to anywhere on the net. How do I turn off case sensitivity for the match target ? I'd like the following line to match "error' or 'ERROR' or 'Error' filter logparse { match("error"); }; but of course it only matches 'error' since by default regex is case sensitive. Basically I'm trying to emulate 'grep -i' I guess I could do this : filter logparse { match("[Ee][Rr][Rr][Oo][Rr]"); }; but it'd be soo much simpler to turn off case sensitivity. And while we're talking regex. Shouldn't the above line actually read like this : filter logparse { match(".+error.+"); }; ? meaning "anything followed by 'error' followed by anything" Both appear to work so I assume the first line is interpreted by syslog-ng like the second line correct ? Help is appreciated stucky
