- **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). If you use the `chat.postMessage` Slack API endpoint, this is required.
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.
Token | If provided, Grafana will upload the generated image via Slack's file.upload API method, not the external image destination. If you use the `chat.postMessage` Slack API endpoint, this is required.
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`, `dedup_key`, 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.
To configure VictorOps, provide the URL from the Grafana Integration and substitute `$routing_key` with a valid key.
> **Note:** The tag `Severity` has special meaning in the [VictorOps Incident Fields](https://help.victorops.com/knowledge-base/incident-fields-glossary/). If an alert panel defines this key, then it replaces the `message_type` in the root of the event sent to VictorOps.
To set up Pushover, you must provide a user key and an API token. Refer to [What is Pushover and how do I use it](https://support.pushover.net/i7-what-is-pushover-and-how-do-i-use-it) for instructions on how to generate them.
Setting | Description

API Token | Application token
User key(s) | A comma-separated list of user keys
Device(s) | A comma-separated list of devices
Priority | The priority alerting nottifications are sent
OK priority | The priority OK notifications are sent; if not set, then OK notifications are sent with the priority set for alerting notifications
Retry | How often (in seconds) the Pushover servers send the same notification to the user. (minimum 30 seconds)
Expire | How many seconds your notification will continue to be retried for (maximum 86400 seconds)
Alerting sound | The sound for alerting notifications
1. 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. For more information about configuring a webhook, refer to [webhooks](https://developers.google.com/hangouts/chat/how-tos/webhooks).
Alertmanager handles alerts sent by client applications such as Prometheus server or Grafana. It takes care of deduplicating, grouping, and routing them to the correct receiver. Grafana notifications can be sent to Alertmanager via a simple incoming webhook. Refer to the official [Prometheus Alertmanager documentation](https://prometheus.io/docs/alerting/alertmanager) for configuration information.
> **Caution:** In case of a high-availability setup, do not load balance traffic between Grafana and Alertmanagers to keep coherence between all your Alertmanager instances. Instead, point Grafana to a list of all Alertmanagers, by listing their URLs comma-separated in the notification channel configuration.
[Zenduty](https://www.zenduty.com) is an incident alerting and response orchestration platform that not alerts the right teams via SMS, Phone(Voice), Email, Slack, Microsoft Teams and Push notifications(Android/iOS) whenever a Grafana alert is triggered, but also helps you rapidly triage and remediate critical, user impacting incidents. Grafana alert are sent to Zenduty through Grafana's native webhook dispatcher. Refer the Zenduty-Grafana [integration documentation](https://docs.zenduty.com/docs/grafana) for configuring the integration.
[Sensu](https://sensu.io) is a complete solution for monitoring and observability at scale. Sensu Go is designed to give you visibility into everything you care about: traditional server closets, containers, applications, the cloud, and more. Grafana notifications can be sent to Sensu Go as events via the API. This operation requires an API Key. Refer to the [Sensu Go documentation](https://docs.sensu.io/sensu-go/latest/operations/control-access/use-apikeys/#api-key-authentication) for information on creating this key.
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
You must configure an [external image storage provider]({{< relref "../administration/configuration/#external-image-storage" >}}) in order to receive images in alert notifications. If your notification channel requires that the image be publicly accessible (e.g. Slack, PagerDuty), configure a provider which uploads the image to a remote image store like Amazon S3, Webdav, Google Cloud Storage, or Azure Blob Storage. Otherwise, the local provider can be used to serve the image directly from Grafana.
> **Note:** Alert notification templating is only available in Grafana v7.4 and above.
The alert notification template feature allows you to take the [label]({{< relref "../getting-started/timeseries-dimensions.md#labels" >}}) value from an alert query and [inject that into alert notifications]({{< relref "./add-notification-template.md" >}}).
