python-virtualenv 46 | cd vsphere-monitor 47 | virtualenv ./env 48 | ./env/bin/pip install -r requirement.txt 49 | ``` 50 | #### 配置 51 | 修改配置文件 `config.py` 52 | ``` 53 | # falcon 54 | endpoint = "vcenter" # 上报给 open-falcon 的 endpoint 55 | push_api = "http://127.0.0.1:6060/api/push" # 上报的 http api 接口 56 | interval = 60 # 上报的 step 间隔 57 | 58 | # vcenter 59 | host = "vcenter.host" # vcenter 的地址 60 | user = "administrator@vsphere.local" # vcenter 的用户名 61 | pwd = "password" # vcenter 的密码 62 | port = 443 # vcenter 的端口 63 | 64 | # esxi 65 | esxi_names = [] # 需要采集的 esxi ，留空则全部采集 66 | 67 | #

78 | 79 | #### 运行 80 | 先尝试跑一下，假定 `vsphere-monitor` 放在 `/opt` 下 81 | ``` 82 | /opt/vsphere-monitor/env/bin/python /opt/vsphere-monitor/vsphere-monitor.py 83 | ``` 84 | 没有问题的话，将他放入定时任务 85 | ``` 86 | crontab -e 87 | 0-59/1 * * * * /opt/vsphere-monitor/env/bin/python /opt/vsphere-monitor/vsphere-monitor.py 88 | ``` 89 | 90 | #### 问题 91 | 部分 vm 可能会采集不到 `vm.net.if.in` 和 `vm.net.if.out` 指标，这是因为网络指标是通过 `vsphere` 的 `PerformanceManager` 采集的。可以在 `vcenter` 中查看虚拟机的 `性能` 图表时，也会发现显示错误 `未指定衡量指标` 或者 `No Metric Specified` 。这是 `vmware` 的 bug，在 `vSphere 6.0 Update 1` 以上版本被修复 92 | 93 | 详见官方 Knowledge —— [在 VMware vSphere Client 6.0 中查看虚拟机网络的实时性能图表时显示错误：未指定衡量指标 (2125021)](https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2125021) 94 | 95 | #### 截图 96 | esxi 97
