15 为 VMware 创建自定义性能计数器名称

概述

VMware 性能计数器路径具有 group/counter[rollup] 格式:

  • group - 性能计数器组,例如 cpu
  • counter - 性能计数器名称,例如 usagemhz
  • rollup - 性能计数器汇总类型,例如 average

所以上面的例子会给出以下计数器路径: cpu/usagemhz[average]

性能计数器组描述、计数器名称和汇总类型可以在 VMware 文档中找到。

可以通过使用 Zabbix 中的脚本监控项来获取内部名称并创建自定义性能计数器名称。

配置

  1. 使用以下参数在主要的VMware主机(存在 eventlog[] 监控项的地方)上创建禁用的脚本监控项:

  • Name: VMware 指标
  • Type: 脚本
  • Key: vmware.metrics
  • Type of information: 文本
  • Script: 复制并粘贴下面提供的 脚本
  • Timeout: 10
  • History: 不存储
  • Enabled: 未标记

脚本

try {
           Zabbix.log(4, 'vmware metrics script');
       
           var result, resp,
           req = new HttpRequest();
           req.addHeader('Content-Type: application/xml');
           req.addHeader('SOAPAction: "urn:vim25/6.0"');
       
           login = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:vim25">\
           <soapenv:Header/>\
           <soapenv:Body>\
               <urn:Login>\
                   <urn:_this type="SessionManager">SessionManager</urn:_this>\
                   <urn:userName>{$VMWARE.USERNAME}</urn:userName>\

               </urn:Login>\
           </soapenv:Body>\
       </soapenv:Envelope>'
           resp = req.post("{$VMWARE.URL}", login);
           if (req.getStatus() != 200) {
               throw 'Response code: '+req.getStatus();
           }
       
           query = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:vim25">\
       <soapenv:Header/>\
           <soapenv:Body>\
               <urn:RetrieveProperties>\
                   <urn:_this type="PropertyCollector">propertyCollector</urn:_this>\
                   <urn:specSet>\
                       <urn:propSet>\
                          <urn:type>PerformanceManager</urn:type>\
                          <urn:pathSet>perfCounter</urn:pathSet>\

                   </urn:specSet>\
               </urn:RetrieveProperties>\
           </soapenv:Body>\
       </soapenv:Envelope>'
           resp = req.post("{$VMWARE.URL}", query);
           if (req.getStatus() != 200) {
               throw 'Response code: '+req.getStatus();
           }
           Zabbix.log(4, 'vmware metrics=' + resp);
           result = resp;
       
           logout = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:vim25">\
           <soapenv:Header/>\
           <soapenv:Body>\
               <urn:Logout>\
                   <urn:_this type="SessionManager">SessionManager</urn:_this>\
               </urn:Logout>\
           </soapenv:Body>\
       </soapenv:Envelope>'
       
           resp = req.post("{$VMWARE.URL}",logout);         
           if (req.getStatus() != 200) {
               throw 'Response code: '+req.getStatus();
           }
       
       } catch (error) {
           Zabbix.log(4, 'vmware call failed : '+error);
           result = {};
       }
       
       return result;

配置监控项后,点击 Test 按钮,然后点击 Get value

将收到的 XML 复制到任何 XML 格式化程序并找到所需的指标。

一个指标的 XML 示例:

<PerfCounterInfo xsi:type="PerfCounterInfo">
           <key>6</key>
           <nameInfo>
               <label>Usage in MHz</label>
               <summary>CPU usage in megahertz during the interval</summary>
               <key>usagemhz</key>
           </nameInfo>
           <groupInfo>
               <label>CPU</label>
               <summary>CPU</summary>
               <key>cpu</key>
           </groupInfo>
           <unitInfo>
               <label>MHz</label>
               <summary>Megahertz</summary>
               <key>megaHertz</key>
           </unitInfo>
           <rollupType>average</rollupType>
           <statsType>rate</statsType>
           <level>1</level>
           <perDeviceLevel>3</perDeviceLevel>
       </PerfCounterInfo>

使用 XPath 从收到的 XML 中提取计数器路径。对于上面的示例,XPath 将是:

字段 xPath
group //groupInfo[../key=6]/key cpu
counter //nameInfo[../key=6]/key usagemhz
rollup //rollupType[../key=6] average

在这个例子中性能计数器路径是: cpu/usagemhz[average]
