日志是supervisor打出来的python日志，且把不同格式的日志打印到了同一批文件里，需求是把带post和ERROR关键字的日志分离，并进入两个不同kafka的topic队列，目前的情况是rsyslog已经收集了nginx的访问日志，不能相互影响，就是说不能直接用if判断做分离，因为可能会日志混掉。要收集的日志格式如下：
ERROR:root:requeue {"withRefresh": false, "localPath": "/data1/ms/cache/file_store_location/n.fdaimg.cn/translate/20170219/oobE-fyarref6029227.jpg?43", "remotePath": "translate/20170219/oobE-fyarref6029227.jpg?43"}INFO:root:2017-02-22T11:53:11.395165, {"withRefresh": false, "localPath": "/data1/ms/cache/file_store_location/n.adfaimg.cn/w/20170222/aue--fyarref6523250.jpeg", "remotePath": "w/20170222/aue--fyarref6523250.jpeg"}INFO:root:post /data1/ms/cache/file_store_location/n.fsdaimg.cn/w/20170222/aue--fyarref6523250.jpeg to w/20170222/aue--fyarref6523250.jpeg took 112.954854965 ms... 操作做之前配置的rsyslog的规则如下：
module(load="imfile")module(load="omkafka")$PreserveFQDN onmain_queue( queue.workerthreads="10" # threads to work on the queue queue.dequeueBatchSize="1000" # max number of messages to process at once queue.size="50000" # max queue size)######################### nginx access #####################$template nginxlog,"xd172\.16\.11\.44`%msg%"ruleset(name="nginxlog") { action( broker=["10.13.88.190:9092","10.13.88.191:9092","10.13.88.192:9092","10.13.88.193:9092"] type="omkafka" topic="cms-nimg-s3" template="nginxlog" partitions.auto="on" ) }input(type="imfile" File="/data1/ms/comos/logs/access_s3.log" Tag="" ruleset="nginxlog" freshStartTail="on" reopenOnTruncate="on" ) 当时想直接用if判断做分离，后来发现所有的日志都会进if判断，完全可能把日志混淆，后来测试发现,ruleset里竟然可以嵌套if判断，神奇的rsyslog，解决了一个大问题，配置如下：
