Using Prometheus+Grafana+VMware-exporter to monitor VMware EXSi Hosts and VMs

This article introduces a simple method to monitor VMware EXSi and VMs with VMware-exporter, related metrics can be pulled by Prometheus, and visualized by Grafana.

Here we use docker to run 4 containers that compose of the entire environment.

First of all, git clone the project from the URL: VMware-ESXI-Monitoring-Tools: Prometheus / Grafana / VMWare ESXi Metrics for Prometheus

then, you need to download docker: Get Docker | Docker Docs, and install the docker for providing docker environment.

Finally, run the command:

复制代码

SMTP_HELLO=[yourdomain.com] SMTP_TO=[[email protected]] SMTP_FROM=[[email protected]] SMTP_SMARTHOST=smtp.gmail.com:587 SMTP_USER=[[email protected]] SMTP_PASS=[your_google_app_password]
HOST_IP=[host_ip_running_docker_compose] VSPHERE_HOST=[esxi_host_ip_or_hostname] VSPHERE_USER=[vsphere_user] VSPHERE_PASS=[vsphere_pass] ./start_containers.sh

If there's no need to use alert function, just remove the SMTP parameters from the command.

That's it!

If you want to get metrics from multiple vCenters, you can modify ./configs/prometheus.yml.tpl to add more jobs, for example,

复制代码

- job_name: 'vmware_vcenter_0'

  ......

  static_configs:

    - targets: 

      - '{{HOST_IP}}:9272'

- job_name: 'vmware_vcenter_1'

  ......

  static_configs:

    - targets: 

      - '{{HOST_IP}}:9273'

Run docker ps to get containers, and docker compose logs to get logs.

If it's too slow to download images, you can configure Aliyun docker image mirror to speed up.

Navigate to 容器镜像服务 to get registry-mirrors

Modify daemon configuration file /etc/docker/daemon.json to use accelerator:

复制代码

sudo mkdir -p /etc/docker 

sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://{{serial number}}.mirror.aliyuncs.com"] } EOF 

sudo systemctl daemon-reload  

sudo systemctl restart docker

After all set. you can get Dashboard template from Grafana Dashboard. Searching the dashboards with filters vmware or exsi and lable of prometheus to get the one you want. Remember to configure the data source first: https://{``{host_ip}}:3000
