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：
123 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"}

操作做之前配置的rsyslog的规则如下：
module(load="imfile")
module(load="omkafka")
$PreserveFQDN on
main_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：
module(load="imfile")
module(load="omkafka")
$PreserveFQDN on
main_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
)
