Server Monitoring Resource Usage Webhook Notifications

In order to receive Server Monitoring Resource Usage webhook notifications, you will need to have the following:

• An Uptime Monitor which has a contact list with Webhooks enabled:
  – http://docs.hetrixtools.com/uptime-monitoring-webhook-notifications/
• Attach a Server Monitor to this Uptime Monitor, and install the Server Agent on your VPS or Dedicated Server:
  – https://docs.hetrixtools.com/install-the-hetrixtools-server-monitor-agent/
• Configure resource usage warnings for this Server Monitor:
  – https://docs.hetrixtools.com/set-resource-usage-warnings/

Once you’ve got all of that configured, whenever you receive Resource Usage alerts, your Webhook URL will receive JSON format data, as well.

General payload parameters:

monitor_id – your monitor’s unique ID (can be found in the link of your monitor’s uptime report);
monitor_name – the label of your uptime monitor;
timestamp – is the Unix time stamp at which the event occurred;

Example of a resource usage webhook notification:

{  
   "monitor_id":"ThisWillBeTheMonitorID32CharLong",
   "monitor_name":"Test Monitor Label",
   "timestamp":1499666613,
   "resource_usage":{  
      "resource_type":"cpu",
      "current_usage":"24.60",
      "average_usage":"25.29",
      "average_minutes":"3"
   }
}

Parameters:
resource_type – describes which resource type this notification is about; possible values:
– cpu
– ram
– disk
– network_inbound
– network_outbound
current_usage – the current usage (percent) for this server monitor (i.e.: the usage taken the same minute the notification is sent out);
average_usage – the average usage (percent) over average_minutes minutes (based on your resource usage warning configuration).

Example of an ‘agent data not sent’ Webhook notification:

{  
   "monitor_id":"ThisWillBeTheMonitorID32CharLong",
   "monitor_name":"Test Monitor Label",
   "timestamp":1499666613,
   "resource_usage":{  
      "resource_type":"agent",
      "error":"no data"
   }
}

Parameters:
resource_type – describes which resource type this notification is about; possible values:
– agent – for server agent data not received notifications
– drive health – for drive health related notifications
– raid – for RAID related notifications
– service – for when any monitored services go down
error – the error that had triggered this webhook notification; possible values:
– no data – no data received from the server agent (applies to resource_type: agent)
– increased errors – for when drive errors are above the defined threshold (applies to resource_type: drive health)
– increased wearout – for when drive wearout is above the defined threshold (applies to resource_type: drive health)
– smart test – for when drive drive SMART test fails (applies to resource_type: drive health)
– raid issues – for RAID detected issues (applies to resource_type: raid)
– <array of services> – the services that are detected down (applies to resource_type: service), example: ["mysql","nginx","ssh"]. This array can contain multiple services at once if there is more than one service detected as down.
