VMware 性能计数器路径采用 group/counter[rollup]
格式,其中:
group
- 性能计数器组,例如 cpucounter
- 性能计数器名称,例如 usagemhzrollup
- 性能计数器聚合类型,例如 average因此,上述示例将生成以下计数器路径:cpu/usagemhz[average]
性能计数器组描述、计数器名称和聚合类型可以在 VMware documentation 中找到。
通过使用 Zabbix 中的脚本 监控项,可以获取内部名称以及 create 自定义性能计数器名称。
1。在主VMware 主机 上创建禁用的脚本 监控项(其中包含 eventlog[] 监控项),参数如下:
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("{$VMWARE.URL}", login);
if (req.getStatus() != 200) {
throw '响应代码: '+req.getStatus();
}
query = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:vim25">\
<soapenv:Header/>\
<soapenv:Body>\
<urn:RetrieveProperties>\
<urn:_this type="PropertyCollector">propertyCollector</urn:_this>\
<urn:specSet>\
<urn:propSet>\
<urn:type>PerformanceManager</urn:type>\
<urn:pathSet>perfCounter</urn:pathSet>\
</urn:propSet>\
<urn:objectSet>\
<urn:obj type="PerformanceManager">PerfMgr</urn:obj>\
</urn:objectSet>\
</urn:specSet>\
</urn:RetrieveProperties>\
</soapenv:Body>\
</soapenv:Envelope>'
resp = req.post("{$VMWARE.URL}", query);
if (req.getStatus() != 200) {
throw '响应代码: '+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 '响应代码: '+req.getStatus();
}
} catch (error) {
Zabbix.log(4, 'vmware 调用失败 : '+error);
result = {};
}
return result;
一旦配置好 监控项,点击 Test 按钮,然后点击 Get value。
将接收到的XML复制到任意XML格式化工具中,并查找所需的指标。
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从接收到的XML中提取计数器路径。以上示例的XPath如下:
字段 | xPath | 值 |
---|---|---|
group | //groupInfo[../key=6]/key | cpu |
counter | //nameInfo[../key=6]/key | usagemhz |
rollup | //rollupType[../key=6] | average |
本例中的性能计数器路径为:cpu/usagemhz[average]
