Hi, Deu to we have multiple collector of GrayLog in multiple locations. I was thinking could I use if else to send log? for example: ``` Module om_udp EXEC if $location =~ /^(us)/\ {\ $collector = 'collector.test.us';\ }\ else\ {\ $collector = 'collector.test.eu';\ } Host $collector Port 15001 OutputType GELF ``` I have tried many statement, but all failure. E.g. string($collector), "$collector", {$collector}, (EXEC $collector;)..etc. I always got the following error. ERROR apr_sockaddr_info failed for [$GLogCollector]:15001; No such host is known. If I config the 'collector.test.us' for Host of output, I can see the $collector is working.

You can do this with filtering as follows: ``` Module om_udp ... Exec $location !~ /^(us)/ drop(); Module om_udp ... Exec $location !~ /^(eu)/ drop(); in => out_us, out_eu ```
