elk基于jolokia监控springboot应用jvm方案

作者: 冬天里的懒喵 | 来源:发表于2018-06-28 18:27 被阅读90次

目前大部分应用都采用springboot 的方式部署，springboot 采用jar包发布，而jvm的运行状态又比较关键，因此用elk对jvm监控进行了集成，步骤如下：

一 springboot 项目配置

对于springboot项目，需要的配置是在pom文件里面增加对jolokia的支持：

<!--开启springboot 健康监控 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<!-- jolokia jmx监控 -->
<dependency>
    <groupId>org.jolokia</groupId>
    <artifactId>jolokia-core</artifactId>
    <version>1.5.0</version>
</dependency>

之后启动springboot项目，可以看到jolokia的加载日志：

启动后可以通过http的get请求对其进行访问（springboot启动端口为18002）：

#请求命令
curl  -XGET http://127.0.0.1:18002/jolokia/version
#返回json
{"request":{"type":"version"},"value":{"agent":"1.5.0","protocol":"7.2","config":{"listenForHttpService":"true","authIgnoreCerts":"false","agentId":"172.16.20.237-7092-7971c2a9-servlet","debug":"false","agentType":"servlet","policyLocation":"classpath:\/jolokia-access.xml","agentContext":"\/jolokia","serializeException":"false","mimeType":"text\/plain","dispatcherClasses":"org.jolokia.http.Jsr160ProxyNotEnabledByDefaultAnymoreDispatcher","authMode":"basic","streaming":"true","canonicalNaming":"true","historyMaxEntries":"10","allowErrorDetails":"true","allowDnsReverseLookup":"true","realm":"jolokia","includeStackTrace":"true","useRestrictorService":"false","debugMaxEntries":"100"},"info":{"product":"tomcat","vendor":"Apache","version":"8.5.15"}},"timestamp":1530178445,"status":200}

能正常得到一个json，则说明jolokia启动成功。另外，如果所在项目使用了shiro或者其他框架进行了权限验证，那么需要对jolokia的API取消权限拦截。
jolokia的相关API请参见：

https://jolokia.org/reference/html/protocol.html

二 beats配置

elk采用beat收集数据，对于jolokia，因为提供了要给接口，因此可以定时查询这个API接口进行采集。因此想到了execbeat 这个github上提供的beat。

#github地址
https://github.com/christiangalsterer/execbeat

需要自行便宜。
execbeat的yml配置如下：

################# Execbeat Configuration Example #######################

############################# Input ############################################
execbeat:

  execs:
    # Each - Commands to execute.
    - 
     cron: "@every 30s"
     command: "curl"
     args: "http://192.168.22.144:8187/jolokia/read/java.lang:type=Memory/"
     document_type: "Memory"
     fields:
       index_name: "springboot"
       application_name: "radar-api"
    - 
     cron: "@every 30s"
     command: "curl"
     args: "http://192.168.22.144:8187/jolokia/read/java.lang:type=GarbageCollector,name=*/"
     document_type: "GC"
     fields:
       index_name: "springboot"
       application_name: "radar-api"
    - 
     cron: "@every 30s"
     command: "curl"
     args: "http://192.168.22.144:8187/jolokia/read/java.lang:type=Threading/"
     document_type: "Threading"
     fields:
       index_name: "springboot"
       application_name: "radar-api"

############################# Output ##########################################

# Configure what outputs to use when sending the data collected by the beat.
# Multiple outputs may be used.
output:
  redis:
    host_topology: 'eth0'
    host: '192.168.21.120'
    port: 6379
    save_topology: true
    index: 'execbeat'
    db: 0
    db_topology: 1

为了后续在一台服务器上监听多个jvm,因此增加了一个自定义字段 application_name。

二 logstash配置

数据通过beats采集，存放到了redis，之后部署了多个logstash节点进行负载均衡。也可以考虑将数据存到kafka，这样的好处在于不用考虑es故障的情况下可能将redis所在服务器的内存撑爆。

01-redis-input.conf 文件

  #SpringBoot监控数据
  redis {
    data_type => "list"
    key => "execbeat"
    host => "192.168.21.120"
    port => 6379
    db => 0
    threads => 1
  }

15-execbeat-filter.conf

##注：此段配置由于之前对springboot的health、activeMQ的jvm做过监控，因此都保留了。
filter{
  if [beat][name] == "execbeat" {
    if [fields][index_name] in ["activemq","springboot"] {
      #删除请求数据为空的所有事件   
      if ![exec][stdout] or [exec][stdout] == "" {
        drop{}
      }  
      else if [type] == "Health" {
        json {
          source => ["[exec][stdout]"]
          target => "Health"
        }
      } else if [type] == "Threading" {
        json {
          source => ["[exec][stdout]"]
          target => "Threading"
        }
      } else if [type] == "Memory" {
        json {
          source => ["[exec][stdout]"]
          target => "Memory"
        }
      } else if [type] == "Queue" {
        json {
          source => ["[exec][stdout]"]
          target => "Queue"
        }
        ruby {
          code => "
            params = event.get('Queue')['value'] && event.get('Queue')['value'].to_hash
            params.keys.each { |k| params[ k.split(',')[1].split('=')[1] ] = params.delete(k) if k.include?',' } unless params.nil?
            params.keys.each { |k| params[ k.gsub('.','_') ] = params.delete(k) if k.include?'.' } unless params.nil?
            event.set('Queue',params)
          "
        }
      } else if [type] == "Topic" {
        json {
          source => ["[exec][stdout]"]
          target => "Topic"
        }
        ruby {
          code => "
            params = event.get('Topic')['value'] && event.get('Topic')['value'].to_hash
            params.keys.each { |k| params[ k.split(',')[1].split('=')[1] ] = params.delete(k) if k.include?',' } unless params.nil?
            params.keys.each { |k| params[ k.gsub('.','_') ] = params.delete(k) if k.include?'.' } unless params.nil?
            event.set('Topic',params)
          "
        }
      } else if [type] == "GC" {
        json {
          source => ["[exec][stdout]"]
          target => "GC"
        }
        ruby {
          code => "
            params = event.get('GC')['value'] && event.get('GC')['value'].to_hash
            params.keys.each { |k| params[ k.split(',')[0].split('=')[1] ] = params.delete(k) if k.include?',' } unless params.nil?
            params.keys.each { |k| params[ k.gsub('.','_') ] = params.delete(k) if k.include?'.' } unless params.nil?
            event.set('GC',params)
          "
        }
      }
      #统一去除curl的stderr信息
      mutate {
        remove_field => ["[exec][stderr]","[exec][stdout]"]
      }

      #删除ruby解析错误的事件  
      if "_rubyexception" in [tags] {
        drop{}
      }    

    } else if  [fields][index_name] == "springcloud"  {
      if [type] == "health" {
        json {
          source => ["[exec][stdout]"]
          target => "health"
        }
        mutate {
          remove_field => ["[exec][stderr]","[exec][stdout]"]
        }
      } else if [type] == "metrics" {
        json {
          source => ["[exec][stdout]"]
          target => "metrics"
        }
        ruby {
          code => "
            params = event.get('metrics') && event.get('metrics').to_hash
            params.keys.each { |k| params[ k.gsub('.','_') ] = params.delete(k) if k.include?'.' } unless params.nil?
            event.set('metrics',params)
          "
        }
        mutate {
          remove_field => ["[exec][stderr]","[exec][stdout]"]
        }
      }
    }
  }
}

上述配置文件支持对activeMQ和springcloud Health的监控。
另外有个比较坑的地方在于，通过curl请求的过程中，由于execbeat中不能增加 -s参数，因此会有很多进度信息输出，最后在脚本中转换处理。实际上也可以修改git的脚本进行处理，考虑到对golang的掌握程度，因此采用了在ruby脚本处理的方案。

30-elasticsearch-output.conf

output {
 if [fields][index_name] == "springboot" {
    elasticsearch {
      hosts => ["192.168.21.23:9201","192.168.21.23:9202","192.168.21.23:9203"]
      sniffing => false
      manage_template => false
      index => "springboot-%{+YYYY.MM.dd}"
    }
  }
}

启动logstash之后，在kibana中就能看到相关的数据了。

采集了GC、Memory、Thread等三类数据，如果需要更多的数据，可以查询jolokia的相关文档，采集所需要的数据。

    }
  }
]

上述是对做的几个图的导出配置，可以组成一个dashboard，效果如下：

jvm监控图就搞定，大家可以根据要求自行配置所需要的图。另外jvm的报警，官方自带的报警功能是需要付费的，因此可以自行开发报警系统，定期查询es中的数据，然后进行阈值配置即可。
