Documentation Grafana documentation Alerting Alerting Notifications

Alert Notifications

Alerting is only available in Grafana v4.0 and above.

When an alert changes state, it sends out notifications. Each alert rule can have multiple notifications. In order to add a notification to an alert rule you first need to add and configure a notification channel (can be email, PagerDuty or other integration). This is done from the Notification Channels page.

Notification Channel Setup

On the Notification Channels page hit the New Channel button to go the page where you can configure and setup a new Notification Channel.

You specify a name and a type, and type specific options. You can also test the notification to make sure it’s setup correctly.

Default (send on all alerts)

When checked, this option will notify for all alert rules - existing and new.

Send reminders

Only available in Grafana v5.3 and above.

When this option is checked additional notifications (reminders) will be sent for triggered alerts. You can specify how often reminders should be sent using number of seconds (s), minutes (m) or hours (h), for example 30s, 3m, 5m or 1h etc.

Important: Alert reminders are sent after rules are evaluated. Therefore a reminder can never be sent more frequently than a configured alert rule evaluation interval.

These examples show how often and when reminders are sent for a triggered alert.

Disable resolve message

When checked, this option will disable resolve message [OK] that is sent when alerting state returns to false.

Supported Notification Types

Grafana ships with the following set of notification types:

Email

To enable email notifications you have to setup SMTP settings in the Grafana config. Email notifications will upload an image of the alert graph to an external image destination if available or fallback to attaching the image to the email. Be aware that if you use the local image storage email servers and clients might not be able to access the image.

Slack

To set up slack you need to configure an incoming webhook url at slack. You can follow their guide on how to do that here. If you want to include screenshots of the firing alerts in the Slack messages you have to configure either the external image destination in Grafana, or a bot integration via Slack Apps. Follow Slack’s guide to set up a bot integration and use the token provided (https://api.slack.com/bot-users), which starts with “xoxb”.

If you are using the token for a slack bot, then you have to invite the bot to the channel you want to send notifications and add the channel to the recipient field.

PagerDuty

To set up PagerDuty, all you have to do is to provide an API key.

Webhook

The webhook notification is a simple way to send information about a state change over HTTP to a custom endpoint. Using this notification you could integrate Grafana into a system of your choosing.

Example json body:

json Copy

{
  "title": "My alert",
  "ruleId": 1,
  "ruleName": "Load peaking!",
  "ruleUrl": "http://url.to.grafana/db/dashboard/my_dashboard?panelId=2",
  "state": "alerting",
  "imageUrl": "http://s3.image.url",
  "message": "Load is peaking. Make sure the traffic is real and spin up more webfronts",
  "evalMatches": [
    {
      "metric": "requests",
      "tags": {},
      "value": 122
    }
  ]
}

• state - The possible values for alert state are: ok, paused, alerting, pending, no_data.

Dingtalk supports the following “message type”: text, link and markdown. Only the link message type is supported.

Kafka

Notifications can be sent to a Kafka topic from Grafana using the Kafka REST Proxy. There are a couple of configuration options which need to be set up in Grafana UI under Kafka Settings:

1. Kafka REST Proxy endpoint.

2. Kafka Topic.

Once these two properties are set, you can send the alerts to Kafka for further processing or throttling.

Google Hangouts Chat

Notifications can be sent by setting up an incoming webhook in Google Hangouts chat. Configuring such a webhook is described here.

All supported notifiers

Enable images in notifications

Grafana can render the panel associated with the alert rule and include that in the notification. Most Notification Channels require that this image be publicly accessible (Slack and PagerDuty for example). In order to include images in alert notifications, Grafana can upload the image to an image store. It currently supports Amazon S3, Webdav, Google Cloud Storage and Azure Blob Storage. So to set that up you need to configure the external image uploader in your grafana-server ini config file.

Be aware that some notifiers requires public access to the image to be able to include it in the notification. So make sure to enable public access to the images. If you’re using local image uploader, your Grafana instance need to be accessible by the internet.

Notification services which need public image access are marked as ’external only'.

Use alert rule tags in notifications

Only available in Grafana v6.3+.

Grafana can include a list of tags (key/value) in the notification. It’s called alert rule tags to contrast with tags parsed from timeseries. It currently supports only the Prometheus Alertmanager notifier.

This is an optional feature. You can get notifications without using alert rule tags.

Configure the link back to Grafana from alert notifications

All alert notifications contain a link back to the triggered alert in the Grafana instance. This url is based on the domain setting in Grafana.
