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

过程如下:

1: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`)
)

2:自定义returners

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reuters:

主要就是returner(ret) 这个函数的定义

cat /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

3fluent采集

客户端配置:

  type tail
  path /var/log/salt/returner
  pos_file /tmp/return_pos.log
  tag os.salt
  format /\"(?.*)\", \"(?\d+)\", (?.*), \"(?.*)\", (?.*)/



    type forward
    flush_interval 1s
    
        host 
        port 

服务端配置:

  type forward
  port 24224
  bind 0.0.0.0



  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

结果查询:

select * from salt_returns where success is not NULL and fun='cmd.run' limit 1;
+------+----------------------+-----------------------------------------+---------------------+---------+---------+---------+
| id | jid | host_id | time | fun | return | success |
