Workflow: Anthem Network uptime Notifications

Monitoring Source:
This workflow is triggered by webhook events sent from Uptime Kuma, a self-hosted monitoring system. When a monitored service changes state (UP or DOWN), Uptime Kuma sends a JSON payload to this webhook endpoint, which then processes the data and forwards formatted notifications to Slack.

Purpose: Receive Uptime Kuma status webhooks and post Slack alerts for DOWN and UP events.

Nodes

1) Webhook

• Type: Webhook (Trigger)
• What it’s for: Entry point that receives the POST request from Uptime Kuma.
• Endpoint path: POST /webhook/Anthemnetworkstatus
• Expected payload: JSON with body.heartbeat and body.monitor

---

2) Code in JavaScript

• Type: Code
• What it’s for: Converts the raw Uptime Kuma webhook payload into clean fields used by the rest of the workflow.
• Key logic:
  • Reads:

- `body.heartbeat` (status, ping, time, msg)
- `body.monitor` (name, hostname/url/type)

• Creates:

- `isDown` → `true` when `heartbeat.status === 0` (Kuma: 0=DOWN, 1=UP)
- `name` → monitor name
- `hostnameOrURL` → monitor hostname/url fallback
- `time` → heartbeat time (fallback: now)
- `status` → `"Down"` or `"Up"`
- `msg` → human readable summary string

• Also passes through:

- `heartbeat`
- `monitor`

---

3) If

• Type: IF (Condition)
• What it’s for: Routes the workflow based on the status.
• Condition:{{$json.isDown}} is true
  • True path (DOWN) → goes to Only if go Down
  • False path (UP) → goes to Only if go up1

---

4) Only if go Down

• Type: HTTP Request (POST to Slack Incoming Webhook)
• What it’s for: Sends a DOWN alert to Slack when isDown=true.
• Message formatting:
  • Title/header: “🚨 Service is DOWN”
  • Color: #e01e5a (red)
  • Includes fields: Service, Status, Target, Time
  • Includes details from heartbeat message / built msg

---

5) Only if go up1

• Type: HTTP Request (POST to Slack Incoming Webhook)
• What it’s for: Sends an UP alert to Slack when isDown=false.
• Message formatting:
  • Title/header: “✅ Service is UP”
  • Color: #2eb886 (green)
  • Includes fields: Service, Status, Target, Time
  • Includes message block with the formatted msg
