- **Name -** Enter a name for this channel. It will be displayed when users add notifications to alert rules.
- **Type -** Select the channel type. Refer to the [List of supported notifiers](#list-of-supported-notifiers) for details.
- **Default (send on all alerts) -** When selected, this option sends a notification on this channel for all alert rules.
- **Include Image -** See [Enable images in notifications](#enable-images-in-notifications-external-image-store) for details.
- **Disable Resolve Message -** When selected, this option disables the resolve message [OK] that is sent when the alerting state returns to false.
- **Send reminders -** 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`.
**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.
Recipient | Allows you to override the Slack recipient. You must either provide a channel Slack ID, a user Slack ID, a username reference (@<user>, all lowercase, no whitespace), or a channel reference (#<channel>, all lowercase, no whitespace).
Mention Users | Optionally mention one or more users in the Slack notification sent by Grafana. You have to refer to users, comma-separated, via their corresponding Slack IDs (which you can find by clicking the overflow button on each user's Slack profile).
Mention Groups | Optionally mention one or more groups in the Slack notification sent by Grafana. You have to refer to groups, comma-separated, via their corresponding Slack IDs (which you can get from each group's Slack profile URL).
Mention Channel | Optionally mention either all channel members or just active ones.
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.
**Note:** The tags `Severity`, `Class`, `Group`, and `Component` have special meaning in the [Pagerduty Common Event Format - PD-CEF](https://support.pagerduty.com/docs/pd-cef). If an alert panel defines these tag keys, then they are transposed to the root of the event sent to Pagerduty. This means they will be available within the Pagerduty UI and Filtering tools. A Severity tag set on an alert overrides the global Severity set on the notification channel if it's a valid level.
6. There will be a Webhook URL in the panel, looks like this: https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxxx. Copy this URL to the grafana Dingtalk setting page and then click "finish".
Notifications can be sent by setting up an incoming webhook in Google Hangouts chat. Configuring such a webhook is described [here](https://developers.google.com/hangouts/chat/how-tos/webhooks).
Squadcast helps you get alerted via Phone call, SMS, Email and Push notifications and lets you take actions on those alerts. Grafana notifications can be sent to Squadcast via a simple incoming webhook. Refer the official [Squadcast support documentation](https://support.squadcast.com/docs/grafana) for configuring these webhooks.
Grafana can render the panel associated with the alert rule as a PNG image and include that in the notification. Read more about the requirements and how to configure
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]({{< relref "../installation/configuration/#external-image-storage" >}}) in your grafana-server ini config file.
Be aware that some notifiers require 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.
