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 cpucounter- 性能计数器名称,例如 usagemhzrollup- 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
- 在主 VMware 主机上创建一个已禁用的 Script 监控项(其中存在 eventlog[] 监控项),并使用以下参数:

- 名称: VMware metrics
- 类型: Script
- 键值: vmware.metrics
- 信息类型: Text
- 脚本: 复制并粘贴下面提供的 脚本
- 超时: 10
- 历史: 不保存
- 启用: 未勾选
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>{$VMWARE.USERNAME}</urn:userName>\
<urn:password>{$VMWARE.PASSWORD}</urn:password>\
</urn:Login>\
</soapenv:Body>\
</soapenv:Envelope>'
resp = req.post("{$VMWARE.URL}", login);
if (req.getStatus() != 200) {
throw 'Response code: '+req.getStatus();
}
query = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:vim25">\
<soapenv:Header/>\
<soapenv:Body>\
<urn:RetrieveProperties>\
<urn:_this type="PropertyCollector">propertyCollector</urn:_this>\
<urn:specSet>\
<urn:propSet>\
<urn:type>PerformanceManager</urn:type>\
<urn:pathSet>perfCounter</urn:pathSet>\
</urn:propSet>\
<urn:objectSet>\
<urn:obj type="PerformanceManager">PerfMgr</urn:obj>\
</urn:objectSet>\
</urn:specSet>\
</urn:RetrieveProperties>\
</soapenv:Body>\
</soapenv:Envelope>'
resp = req.post("{$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;
配置好监控项后,点击 Test 按钮,然后点击 Get value。

将收到的 XML 复制到任意 XML 格式化工具中,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。以上示例中,XPath 为:
| field | xPath | value |
|---|---|---|
| group | //groupInfo[../key=6]/key | cpu |
| counter | //nameInfo[../key=6]/key | usagemhz |
| rollup | //rollupType[../key=6] | average |
在这种情况下,得到的性能计数器路径为:cpu/usagemhz[average]
