Send Data from Edge Delta to a Webhook
2 minute read
Overview
The Webhook node sends triggered alerts to a webhook based on an incoming signal. These signals can be generated by a threshold node on the edge. Alternatively, you can create a webhook integration, which can be triggered by a monitor in the backend, and which does not need to be deployed in a particular pipeline.
See Send Events from an Edge Delta Pipeline to Slack for an example using Slack.
To create a webhook node:
- Click Add Node.
- Select Webhook Destination.
- Specify the webhook endpoint.
Example 1
This example uses a webhook node. It follows on from configure a threshold node. This example requires a Teams channel endpoint.
- Enter a suppression window of
20m. This prevents the notification channel from being flooded for 20 minutes after receiving the first alert. - Expand Advanced Settings and enter the following Payload:
{"text": "More than 1% of NGINX traffic is a 5xx error in the past minute."}
- Click Save Changes.
- Connect the Threshold node’s output to the Webhook node.
- Click Review Changes.
- Click Save Changes.
If the threshold is met a notification is sent to the application consuming the webhook:
Example 2
In this example, a rich payload is sent to a webhook node with dynamic content pulled from the alert fields. This example requires a Teams channel endpoint.
- name: richtemplate
type: webhook_output
endpoint: https://myco.webhook.office.com/webhookb2/88264c11-0bb8-44fc-/IncomingWebhook/1a2b3c4d5e6f/abcdef123456
suppression_window: 1m0s
payload: " {\n \"type\":\"message\",\n \"attachments\":[\n {\n
\ \"contentType\":\"application/vnd.microsoft.card.adaptive\",\n \"contentUrl\":null,\n
\ \"content\":{\n \"$schema\":\"http://adaptivecards.io/schemas/adaptive-card.json\",\n
\ \"type\":\"AdaptiveCard\",\n \"version\":\"1.2\",\n
\ \"body\":[\n {\n \"type\": \"TextBlock\",\n
\ \"text\": \"**{{ index .item.signal \"title\" }}**\"\n },\n
\ {\n \"type\": \"TextBlock\",\n \"text\":
\"**Tag**: {{ index .item.resource \"ed.tag\" }}\\n\\r**Host**: {{ index .item.resource
\"host.name\" }}\\n\\r**Description**: {{ js .item.signal.description }}\\n\\r**Signal

\"name\" }}\\n\\r**Value**: {{ index .item.signal \"value\" }}\"\n }\n
\ ]\n }\n }\n ]\n } "
The payload is rendered in the receiving application, in this instance Microsoft Teams:
