saltstack自定义returner之利用fluent+mysql进行结果收集

mysql表结构

自定义returner

fluent采集

客户端配置

服务端配置

背景: salt自带的有很多可选的returner,但是都需要在minion做配置,我感觉这点挺操蛋,而且正好我们平台上在使用fluent做采集,于是就自定义一个reutren,然后用fluent采集,处理,入库

具体操作过程如下：

mysql表结构

CREATE TABLE `fluent`;

CREATE TABLE `salt_returns` (

  `id` mediumint(9) NOT NULL AUTO_INCREMENT,

  `jid` char(20) DEFAULT NULL,

  `host_id` varchar(48) DEFAULT NULL,

  `time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,

  `fun` varchar(30) DEFAULT NULL,

  `return` text,

  `success` char(5) DEFAULT NULL,

  PRIMARY KEY (`id`),

  KEY `idx_host_id` (`host_id`)

自定义returner

创建默认自定义return的目录,这个目录虽然是默认的,但是默认并没有创建

# mkdir /srv/salt/_returners

自定义returner

主要就是returner(ret) 这个函数的定义

/srv/salt/_returners/lcoal_return.py

#coding=utf8

import json

def __virtual__():

    return ‘local_return‘

def returner(ret):

    ‘‘‘

    Return data to the local file

    ‘‘‘

    result_file = ‘/var/local/salt/returner‘

    result = file(result_file,‘a+‘)

    result.write(str(json.dumps(ret.values()))[1:-1]+‘\n‘)

    result.close()

同步到所有节点：

salt ‘*‘ saltutil.sync_returners

执行命令

salt ‘*‘ cmd.run ‘ls /var‘ --return local_return

查看结果：

# cat /var/log/salt/returner

"cmd.run", "20130524052158870765", "cache\ncvs\ndb\nempty\ngames\nlib\nlocal\nlock\nlog\nmail\nnis\nopt\npreserve\nrun\nspool\ntmp\nwww\nyp", "minion1", true

fluent采集

客户端配置

<source>

  type tail

  path /var/log/salt/returner

  pos_file /tmp/return_pos.log

  tag os.salt

  format /\"(?<fun>.*)\", \"(?<jid>\d+)\", (?<return>.*), \"(?<id>.*)\", (?<success>.*)/

</source>

<match os.*>

    type forward

    flush_interval 1s

    <server>

        host {{ pillar[‘host‘] }}

        port {{ pillar[‘port‘] }}

    </server>

</match>

服务端配置

<source>

  type forward

  port 24224

  bind 0.0.0.0

</source>

<match host.os.salt>

  type mysql

  host localhost

  database fluent

  username fluent

  password fluent

  key_names jid,id,fun,return,success

  sql INSERT INTO salt_returns (jid,host_id,fun,`return`,success) VALUES (?,?,?,?,?)

  flush_interval 5s

</match>

结果查询:

select * from salt_returns where success is not NULL and fun=‘cmd.run‘ limit 1;
