Setup Monitoring Plugin

The following are steps to install and configure the plugin for monitoring on Ubuntu.

  • Download binary from release page.
  • Rename the file to cachet-monitor.
  • Make the file executable with the command.
sudo chmod +x cachet-monitor
  • Put the executable in a PATH directory, so you can access it directly via terminal. So, I suggest you move under /usr/local/bin.
  • Create a config.json file by running the following command.
sudo nano config.json
  • Copy the below code into it and save the file.
  "api": {
    "url": "",
    "token": "9yMHsdioQosnyVK4iCVR",
    "insecure": false
  "date_format": "02/01/2006 15:04:05 MST",
  "monitors": [
      "name": "google",
      "target": "",
      "strict": true,
      "method": "POST",
      "component_id": 1,
      "metric_id": 4,
      "template": {
        "investigating": {
          "subject": "{{ .Monitor.Name }} - {{ .SystemName }}",
          "message": "{{ .Monitor.Name }} check **failed** (server time: {{ .now }})\n\n{{ .FailReason }}"
        "fixed": {
          "subject": "I HAVE BEEN FIXED"
      "interval": 1,
      "timeout": 1,
      "threshold": 80,
      "expected_status_code": 200
  • Now, test your configuration with this command.
cachet-monitor -c config.json
  • If everything works well, move to the next section and create a Linux service.

Creating Linux Service

The following are steps to create and start a Linux service to automate the monitoring process.

sudo nano cachet-monitor.service
  • Copy the below code into it and save the file.
Description=Cachet Monitor

ExecStart=cachet-monitor -c /root/config.json
Environment=USER=root HOME=/root

sudo systemctl daemon-reload
  • Enable cachet-monitor service by running the command, so it can load on system startup.
sudo systemctl enable cachet-monitor.service
