flume如何实时读取不断追加的日志
1. 日志文件每天roate一个新文件a)方案一
There is no way the tail command itself can automatically switch to the new file with a different name when the date changes. Thus, you have to kill the old tail and start a new one in due time.
while
tail -F `date +%Y%m%d.log`& sleep $(expr `date +%s -d'day 0'` - `date +%s`)
dokill $!
done
b) 方案二
I am using flume-ng exec tailing rotated log files too. Here's my solution:
originAgent.sources.originSource2.type = exec
originAgent.sources.originSource2.command = locktail_rotate.sh /path/to/test.DATE_ROTATE.log 'date +"%Y%m%d"'
And you can checkout locktail_rotate.sh from here. https://github.com/kylelin/locktail
