When an alert changes state it sends out notifications. Each alert rule can have
multiple notifications. But in order to add a notification to an alert rule you first need
to add and configure a `notification` object. This is done from the Alerting/Notifications page.
When an alert changes state it sends a notification. One alert can be associated with multiple notifications. You can also configure notifications to be sent for all alerts within Grafana to make sure you won’t miss to configure notifications for an alert. ## Notification Setup
On the notifications list page hit the `New Notification` button to go the the page where you
can configure and setup a new notification.
You can find the alert notification page in the main menu under alerting. You you specify name and type, and type specific options. You can also test the notification to make
sure it's working and setup correctly.

### Send on all alerts
<img class="no-shadow" src="/img/docs/v4/alerttab_notifications_submenu.png"> This option will make this notification used for all alert rules, existing and new.
## Supported notification types
Click the `+` button to add a new notification and the `x` to remove. Notifications with a blue backgrounds are enabled by default for all alerts and cannot be modified from this view. Grafana ships with a set of notification types. More will be added in future releases.

## Default notifications
On the notifications list page (`/alerting/notifications`) you can see all notifiers that have been enabled by default. To make an notification enabled by default
you can check the `Send on all alerts` checkbox on the notification edit page.
## Testing
You can test an notification on the edit page by clicking the `Send Test` button. Grafana will then send test data based on the info on the edit page. This is a simple way of making sure that notifications are working as intended.

To set up slack you need to configure an incoming webhook url at slack. You can follow their guide for how to do that https://api.slack.com/incoming-webhooks

## Enable screenshot of alerting graphs # Enable images in notifications {#external-image-store}
Some notifiers requires you to configure the [external image uploader](/installation/configuration/#external-image-storage) to be able to upload screenshots of the alerts. This is not a requirement for any notifier within Grafana but we strongly encourage you to use it since the alert notifications give the recipient very valuable information.
Grafan can render the panel associated with the alert rule and include that in the notification. Some types
of notifications require that this image be publicly accessable (Slack for example). In order to support
images in notifications like Slack Grafana can upload the image to an image store. It currently supports
Amazon S3 for this and Webdav. So to set that up you need to configure the
[external image uploader](/installation/configuration/#external-image-storage) in your grafana-server ini
config file.
This is not an optional requirement, you can get slack and email notifications without setting this up.

## Notifications
In alert tab you can also specify alert rule notifications along with a detailed messsage about the alert rule.
The message can contain anything, information about how you might solve the issue, link to runbook etc.
The actual notifications are configured and shared between multiple alerts. Read the
