In our case, many of the hosts are Windows instances. So, in this case, we have decided to use the wmi_exporter, written by Martin Lindhe, which is also Open Source.
The setup it’s quite easy:
- We download the latest release of the wmi_exporter, we install it on the host machine, and it will install a Windows Service, which will use the WMI API to get all the information about the instance. On the Services list, we can see it running.
- After that, we can check the metrics by using the browser in http://localhost:9182/metrics, directly. We can also here check if all the metrics we need are enabled. Otherwise we might need to enable additional collectors on the wmi_exporter (either by passing parameters while installing it, or by changing the configs once it was installed).
Example:
Server:
msiexec /i wmi_exporter-0.7.0-amd64.msi ENABLED_COLLECTORS=os,cpu,cs,logical_disk,memory,net,system
Hyper-V:
msiexec /i wmi_exporter-0.7.0-amd64.msi ENABLED_COLLECTORS=os,cpu,cs,hyperv,logical_disk,memory,net,service,system
.\wmi_exporter.exe --collectors.enabled "os,cpu,cs,hyperv,logical_disk,memory,net,service,system"
AD:
msiexec /i wmi_exporter-0.7.0-amd64.msi ENABLED_COLLECTORS=os,cpu,cs,ad,logical_disk,memory,net,system
1C Server:
msiexec /i wmi_exporter-0.7.0-amd64.msi ENABLED_COLLECTORS=os,cpu,cs,logical_disk,memory,net,system,mssql
