saltstack结合Elasticsearch来做salt运行结果展现

salt尽管好用可是机器管理的越来越多，通过cli的结果输出方式查看运行结果越来越多不能满足我的需求。并且作为一个推动运维自己主动化的攻城狮，使用这样的人眼查看运行结果的方式简直土到掉渣。尽管别人看起来逼格非常高。但谁累谁知道。。。因为以上原因，给各位推荐一种逼格更高的结果查看方式：

salt returners

先来看一下官方结构图：

Send data returned by Salt Minions to another system, such as a database. Returners can run on the Salt Minion or on the Salt Master.

这个图上画的是redis，事实上官方给出的returners有非常多非常多。这次为了装逼。哦不正确。为了更好地筛选和过滤salt的运行结果，我选用了elasticsearch+kibana这样的展现方式，优点是es提供一个准实时的全文检索引擎。这样我们能够实时的想搜什么搜什么，多维度过滤，而kibana提供的是便捷的用户界面和帅的一逼的绘图界面！

可是。这两者是怎么结合起来的呢，非常easy，用一个es支持salt也支持的数据中转站即可了。我选择的是kafka。当然你也能够用rsyslog。redis，等等，任君选择

以下就以 salt-minion -> kafka -> logstash -> elasticseach <- kibana <- 你的浏览器 这条主线进行说明，有纰漏的地方欢迎在评论里指正，谢谢！

如今张成果图镇楼：

以下正时開始：

1. salt-minion端的配置：

1.1 改动minion配置文件，这对于会用salt的我们来说改1w台机器就是分分钟的事儿嘛。但注意。改完要重新启动minion进程。

/etc/salt/minion：

#kafka broker主机，能够配置多个
returner.kafka.hostnames:
  - "10.64.0.1"
  - "10.64.0.2"
  - "10.64.0.3"

#kafka topic名称
returner.kafka.topic: 'saltstack-topic'

1.2 改动官方returner文件源码，此处高深莫測。先按下不表

2.kafka 差点儿不用配置。正常能用就可以。顺便推荐一下kafka manager真好用。从此再也不用记命令了。

https://github.com/yahoo/kafka-manager

3.logstash 作为刚才minion发送到kafka数据的消费者，拿到kafka的数据后按json格式存到es中

3.1 logstash.conf：

input {
  kafka {
    #zk 连接串
    zk_connect => '10.64.0.1:2181,10.64.0.2:2181,10.64.0.3:2181,10.64.1.174:2181,10.64.1.175:2181'
    #与刚才配置的topic一致
    group_id => 'logstash-saltstack'
    topic_id => 'saltstack-topic'
    consumer_id => 'logstash-saltstack-consumer-{{ grains["id"] }}'
    consumer_threads => 1
    queue_size => 200
    codec => plain
  }
}

filter {
  mutate {
    add_field => { "fromAgent" => "logstash-saltstack-{{ grains["id"] }}" }
  }
  json {
    source => "message"
  }
  mutate {
    remove_field => [ "message" ]
    convert => { "fun_args" => "string" }
    rename => { "__run_num__" => "run_num" }
  }
}

output {
  elasticsearch {
    #输出到es
    hosts => ["10.64.0.1:9200","10.64.0.2:9200","10.64.0.3:9200"]
    index => "saltstack-%{+YYYY.MM}"
    flush_size => 3000
    idle_flush_time => 2
    workers => 2
  }
  #stdout { codec => rubydebug }
}

这里有个小坑，顺便解释一下刚才按下不表的为啥非要改源代码：es收数据的时候会把json全都拆成嵌套的kv格式存储，啥意思呢，请看图：

这是两个命令运行的不同返回，问题在哪儿呢？问题就在10.64.0.1这个key的value。一会儿是boolen型一会儿是nested型，这样es就没法办了。一个字段的类型实在mapping或者第一次创建数据时确定的。不能随便更改，这样就造成了es不能接收数据的问题。

怎么解决？開始我尝试了改动logstash的配置，只是那个实在不灵活。并且你注意看第二个salt运行的结果，是在一个大json里面的，这样我搜索起来匹配上的话也是一整条数据。还是不方便我看结果。

针对以上两点我还是认为小改一下salt的returners，改动的地方例如以下（每台minion都要改。只是这次不用重新启动了）：

/usr/lib/python2.6/site-packages/salt/returners/kafka_return.py：

def returner(ret):
    '''
    Return information to a Kafka server
    '''
    if __salt__['config.option']('returner.kafka.topic'):
        topic = __salt__['config.option']('returner.kafka.topic')

        conn = _get_conn(ret)
        producer = SimpleProducer(conn)
        if ret["return"] == True or ret["return"] == False:
            producer.send_messages(topic, json.dumps(ret))
        else:
            for retKey in ret["return"]:
                myRet = {}
                myRet["id"] = ret["id"]
                myRet["fun"] = ret["fun"]
                myRet["fun_args"] = ret["fun_args"]
                myRet["jid"] = ret["jid"]
                myRet["retcode"] = ret["retcode"]
                for key in ret["return"][retKey]:
                    myRet[key] = ret["return"][retKey][key]
                retKeys = retKey.split("_|-")
                for i in range(0,len(retKeys)):
                    myRet["key"+str(i)] = retKeys[i]
                producer.send_messages(topic, json.dumps(myRet))

        _close_conn(conn)
    else:
        log.error('Unable to find kafka returner config option: topic')

至此我们就应该能在es里看到每一个动作一条记录的salt结果了。

4. es 还是没啥可配置的，正常运转就能够

5. kibana

首先。我用的是kibana 3，这个须要es <2.0版本号的配合，不要赶新潮装es2，这样就用不了我的模板啦

5.1 加载kibana模板

把以下的内容存成一个文件，然后在kibana中选择加载。然后赶紧跑个salt任务试试

神马？没有，是这样。我忘了跟你说以后跑任务的时候要加个參数才干在es里看到哦：

salt 你要运行的命令 --return kafka

这样你就得到了開始看到的那个激动人心的逼格界面。 我有啥没说清楚的欢迎在以下评论里写明，我会尽力解答。谢谢！
