Fluency+MongoDB搭建日志系统中的几个问题

error=quot;Unknown output plugin

1.运行时如下错误，

error="Unknown output plugin 'mongo'. Run 'gem search -rd fluent-plugin' to find plugins"
搜索mongodb插件
gem search -rd fluent-plugin-mongo
得到结果
*** REMOTE GEMS ***


fluent-plugin-mongo (0.6.7)
Author: Masahiro Nakagawa
Homepage: https://github.com/fluent/fluent-plugin-mongo


MongoDB plugin for Fluent event collector
安装这个插件
gem install fluent-plugin-mongo


2、运行的时候可能会得到如下提示
**Notice: C extension not loaded. This is required for optimum MongoDB Ruby driver performance.
You can install the extension as follows:
gem install bson_ext


If you continue to receive this message after installing, make sure that the
bson_ext gem is in your load path and that the bson_ext and mongo gems are of the same version.
按照上述提示执行 gem install bson_ext

3、flunt.conf

type tail
path /home/aircom/mongodb-linux-i686-2.0.6/bin/logs/1001.log
format /^*(?.*)$/
#format /^(?[^ ]* [^ ]* [^ ]*) (?[^ ]*) (?[a-zA-Z0-9_\/\.\-]*)(?:\[(?[0-9]+)\])?[^\:]*\: *(?.*)$/
#time_format %b %d %H:%M:%S
tag mongo.apache


type mongo
database apache
collection fmongo
host Server202
port 10001
flush_interval 10s

4、login primary node run command

PRIMARY> db.fmongo.find().sort({"_id":-1})
{ "_id" : ObjectId("5062d3700ce0ea43fc000387"), "message" : "Wed Sep 26 18:05:28 [initandlisten] connection accepted from 192.168.19.201:34114 #3204", "time" : ISODate("2012-09-26T10:05:28Z") }

{ "_id" : ObjectId("5062d3700ce0ea43fc000385"), "message" : "Wed Sep 26 18:05:28 [initandlisten] connection accepted from 192.168.19.201:34113 #3203", "time" : ISODate("2012-09-26T10:05:28Z") }

5、fluentd 配置正常时的启动日志

fluentd -c fluent.conf -vv &
