# Alerts overview
Alerts allow you to identify problems in your system moments after they occur. By quickly identifying unintended changes in your system, you can minimize disruptions to your services.
Alerts consists of two parts:
- Alert rules - When the alert is triggered. Alert rules are defined by one or more conditions that are regularly evaluated by Grafana.
- Notification channel - How the alert is delivered. When the conditions of an alert rule are met, the Grafana notifies the channels configured for that alert.
Currently only the graph panel visualization supports alerts.
## Alert tasks
You can perform the following tasks for alerts:
- [Add or edit an alert notification channel]({{< relref "notifications.md" >}})
- [Create an alert rule]({{< relref "create-alerts.md" >}})
- [View existing alert rules and their current state]({{< relref "view-alerts.md" >}})
- [Test alert rules and troubleshoot]({{< relref "troubleshoot-alerts.md" >}})
## Clustering
Currently alerting supports a limited form of high availability. Since v4.2.0 of Grafana, alert notifications are deduped when running multiple servers. This means all alerts are executed on every server but no duplicate alert notifications are sent due to the deduping logic. Proper load balancing of alerts will be introduced in the future.
## Notifications
You can also set alert rule notifications along with a detailed message about the alert rule. The message can contain anything: information about how you might solve the issue, link to runbook, and so on.
The actual notifications are configured and shared between multiple alerts.
## Alert execution
Alert rules are evaluated in the Grafana backend in a scheduler and query execution engine that is part
of core Grafana. Only some data sources are supported right now. They include `Graphite`, `Prometheus`, `InfluxDB`, `Elasticsearch`,
`Stackdriver`, `Cloudwatch`, `Azure Monitor`, `MySQL`, `PostgreSQL`, `MSSQL`, `OpenTSDB`, `Oracle`, and `Azure Data Explorer`.
## Metrics from the alert engine
The alert engine publishes some internal metrics about itself. You can read more about how Grafana publishes [internal metrics]({{< relref "../administration/metrics/" >}}).
Description | Type | Metric name
---------- | ----------- | ----------
Total number of alerts | counter | `alerting.active_alerts`
Alert execution result | counter | `alerting.result`
Notifications sent counter | counter | `alerting.notifications_sent`
Alert execution timer | timer | `alerting.execution_time`

# Create alerts
Grafana alerting allows you to attach rules to your dashboard panels. When you save the dashboard, Grafana extracts the alert rules into a separate alert rule storage and schedules them for evaluation.
{{< imgbox max-width="1000px" img="/img/docs/alerting/drag_handles_gif.gif" caption="Alerting overview" >}}
In the Alert tab of the graph panel you can configure how often the alert rule should be evaluated and the conditions that need to be met for the alert to change state and trigger its [notifications]({{< relref "notifications.md" >}}).
Currently only the graph panel supports alert rules.
## Add or edit an alert rule
1. Navigate to the panel you want to add or edit an alert rule for, click the title, and then click **Edit**.
1. On the Alert tab, click **Create Alert**. If an alert already exists for this panel, then you can just edit the fields on the Alert tab.
1. Fill out the fields. Descriptions are listed below in [Alert rule fields](#alert-rule-fields).
1. When you have finished writing your rule, click **Save** in the upper right corner to save alert rule and the dashboard.
1. (Optional but recommended) Click **Test rule** to make sure the rule returns the results you expect.
## Delete an alert
To delete an alert, scroll to the bottom of the alert and then click **Delete**.
## Alert rule fields
This section describes the fields you fill out to create an alert.
### Rule
- **Name -** Enter a descriptive name. The name will be displayed in the Alert Rules list.
- **Evaluate every -** Specify how often the scheduler should evaluate the alert rule. This is referred to as the _evaluation interval_.
- **For -** Specify how long the query needs to violate the configured thresholds before the alert notification triggers.
You can set a minimum evaluation interval in the `alerting.min_interval_seconds` config field, to set a minimum time between evaluations. Refer to [Configuration]({{< relref "../installation/configuration.md" >}}#min-interval-seconds) for more information.
> **Caution:** Do not use `For` with the `If no data or all values are null` setting set to `No Data`. The triggering of `No Data` will trigger instantly and not take `For` into consideration. This may also result in that an OK notification not being sent if alert transitions from `No Data -> Pending -> OK`.
If an alert rule has a configured `For` and the query violates the configured threshold, then it will first go from `OK` to `Pending`. Going from `OK` to `Pending` Grafana will not send any notifications. Once the alert rule has been firing for more than `For` duration, it will change to `Alerting` and send alert notifications.
Typically, it's always a good idea to use this setting since it's often worse to get false positive than wait a few minutes before the alert notification triggers. Looking at the `Alert list` or `Alert list panels` you will be able to see alerts in pending state.
Below you can see an example timeline of an alert using the `For` setting. At ~16:04 the alert state changes to `Pending` and after 4 minutes it changes to `Alerting` which is when alert notifications are sent. Once the series falls back to normal the alert rule goes back to `OK`.
{{< imgbox img="/img/docs/v54/alerting-for-dark-theme.png" caption="Alerting For" >}}
{{< imgbox max-width="40%" img="/img/docs/v4/alerting_conditions.png" caption="Alerting Conditions" >}}
### Conditions
Currently the only condition type that exists is a `Query` condition that allows you to
specify a query letter, time range and an aggregation function.
#### Query condition example
```sql
avg() OF query(A, 15m, now) IS BELOW 14
```
- `avg()` Controls how the values for **each** series should be reduced to a value that can be compared against the threshold. Click on the function to change it to another aggregation function.
- `query(A, 15m, now)` The letter defines what query to execute from the **Metrics** tab. The second two parameters define the time range, `15m, now` means 15 minutes ago to now. You can also do `10m, now-2m` to define a time range that will be 10 minutes ago to 2 minutes ago. This is useful if you want to ignore the last 2 minutes of data.
- `IS BELOW 14` Defines the type of threshold and the threshold value. You can click on `IS BELOW` to change the type of threshold.
The query used in an alert rule cannot contain any template variables. Currently we only support `AND` and `OR` operators between conditions and they are executed serially.
For example, we have 3 conditions in the following order:
*condition:A(evaluates to: TRUE) OR condition:B(evaluates to: FALSE) AND condition:C(evaluates to: TRUE)*
so the result will be calculated as ((TRUE OR FALSE) AND TRUE) = TRUE.
We plan to add other condition types in the future, like `Other Alert`, where you can include the state of another alert in your conditions, and `Time Of Day`.
#### Multiple Series
If a query returns multiple series then the aggregation function and threshold check will be evaluated for each series. What Grafana does not do currently is track alert rule state **per series**. This has implications that are detailed in the scenario below.
- Alert condition with query that returns 2 series: **server1** and **server2**
- **server1** series causes the alert rule to fire and switch to state `Alerting`
- Notifications are sent out with message: _load peaking (server1)_
- In a subsequence evaluation of the same alert rule the **server2** series also cause the alert rule to fire
- No new notifications are sent as the alert rule is already in state `Alerting`.
So as you can see from the above scenario Grafana will not send out notifications when other series cause the alert to fire if the rule already is in state `Alerting`. To improve support for queries that return multiple series we plan to track state **per series** in a future release.
> Starting with Grafana v5.3 you can configure reminders to be sent for triggered alerts. This will send additional notifications
> when an alert continues to fire. If other series (like server2 in the example above) also cause the alert rule to fire they will be included in the reminder notification. Depending on what notification channel you're using you may be able to take advantage of this feature for identifying new/existing series causing alert to fire.
### No Data & Error Handling
Below are conditions you can configure how the rule evaluation engine should handle queries that return no data or only null values.
No Data Option | Description
------------ | -------------
No Data | Set alert rule state to `NoData`
Alerting | Set alert rule state to `Alerting`
Keep Last State | Keep the current alert rule state, what ever it is.
Ok | Not sure why you would want to send yourself an alert when things are okay, but you could.
### Execution errors or timeouts
Tell Grafana how to handle execution or timeout errors.
Error or timeout option | Description
------------ | -------------
Alerting | Set alert rule state to `Alerting`
Keep Last State | Keep the current alert rule state, what ever it is.
If you have an unreliable time series store from which queries sometime timeout or fail randomly you can set this option to `Keep Last State` in order to basically ignore them.
## Notifications
In alert tab you can also specify alert rule notifications along with a detailed message about the alert rule. The message can contain anything, information about how you might solve the issue, link to runbook, and so on.
The actual notifications are configured and shared between multiple alerts. Read
[Alert notifications]({{< relref "notifications.md" >}}) for information on how to configure and set up notifications.
- **Send to -** Select an alert notification channel if you have one set up.
- **Message -** Enter a message to be sent on the notification channel. The message can be in text, markdown, or HTML format. It can include links and variables as well.
- **Tags -** Specify a list of tags (key/value) to be included in the notification. It is only supported by [some notifiers]({{< relref "notifications/#all-supported-notifiers" >}}).
## Alert state history and annotations
Alert state changes are recorded in the internal annotation table in Grafana's database. The state changes are visualized as annotations in the alert rule's graph panel. You can also go into the `State history` submenu in the alert tab to view and clear state history.

# Alert Notifications
> Alerting is only available in Grafana v4.0 and above.
# Alert notifications
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
to add and configure a `notification` channel (can be email, PagerDuty, or other integration).
On the Notification Channels page hit the `New Channel` button to go the page where you
can configure and setup a new Notification Channel.
This is done from the Notification channels page.
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)
> **Note:** Alerting is only available in Grafana v4.0 and above.
When checked, this option will notify for all alert rules - existing and new.
## Add a notification channel

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.
- **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]({{< relref "rules/#name-evaluation-interval" >}}).

# Alerting Engine and Rules Guide
Alerting in Grafana allows you to attach rules to your dashboard panels. When you save the dashboard,
Grafana will extract the alert rules into a separate alert rule storage and schedule them for evaluation.
{{< imgbox max-width="40%" img="/img/docs/v4/drag_handles_gif.gif" caption="Alerting overview" >}}
In the alert tab of the graph panel you can configure how often the alert rule should be evaluated
and the conditions that need to be met for the alert to change state and trigger its
[notifications]({{< relref "notifications.md" >}}).
## Execution
The alert rules are evaluated in the Grafana backend in a scheduler and query execution engine that is part
of core Grafana. Only some data sources are supported right now. They include `Graphite`, `Prometheus`, `InfluxDB`, `Elasticsearch`,
`Stackdriver`, `Cloudwatch`, `Azure Monitor`, `MySQL`, `PostgreSQL`, `MSSQL`, `OpenTSDB`, `Oracle`, and `Azure Data Explorer`.
## Clustering
Currently alerting supports a limited form of high availability. Since v4.2.0 of Grafana, alert notifications are deduped when running multiple servers. This means all alerts are executed on every server but no duplicate alert notifications are sent due to the deduping logic. Proper load balancing of alerts will be introduced in the future.
<div class="clearfix"></div>
## Rule Config
Currently only the graph panel supports alert rules.
### Name and Evaluation interval
Here you can specify the name of the alert rule and how often the scheduler should evaluate the alert rule.
**Note:** You can set a minimum interval in the `alerting.min_interval_seconds` config field, to set a minimum time between evaluations. Check out the [[configuration]]({{< relref "../installation/configuration.md" >}}#min-interval-seconds) page for more information.
### For
> **Important note regarding No Data:**
>
> Do not use `For` with the `If no data or all values are null` setting set to `No Data`. The triggering of `No Data` will trigger instantly and not take `For` into consideration. This may also result in that an OK notification not being sent if alert transitions from `No Data -> Pending -> OK`.
If an alert rule has a configured `For` and the query violates the configured threshold it will first go from `OK` to `Pending`. Going from `OK` to `Pending` Grafana will not send any notifications. Once the alert rule has been firing for more than `For` duration, it will change to `Alerting` and send alert notifications.
Typically, it's always a good idea to use this setting since it's often worse to get false positive than wait a few minutes before the alert notification triggers. Looking at the `Alert list` or `Alert list panels` you will be able to see alerts in pending state.
Below you can see an example timeline of an alert using the `For` setting. At ~16:04 the alert state changes to `Pending` and after 4 minutes it changes to `Alerting` which is when alert notifications are sent. Once the series falls back to normal the alert rule goes back to `OK`.
{{< imgbox img="/img/docs/v54/alerting-for-dark-theme.png" caption="Alerting For" >}}
{{< imgbox max-width="40%" img="/img/docs/v4/alerting_conditions.png" caption="Alerting Conditions" >}}
### Conditions
Currently the only condition type that exists is a `Query` condition that allows you to
specify a query letter, time range and an aggregation function.
### Query condition example
```sql
avg() OF query(A, 15m, now) IS BELOW 14
```
- `avg()` Controls how the values for **each** series should be reduced to a value that can be compared against the threshold. Click on the function to change it to another aggregation function.
- `query(A, 15m, now)` The letter defines what query to execute from the **Metrics** tab. The second two parameters define the time range, `15m, now` means 15 minutes ago to now. You can also do `10m, now-2m` to define a time range that will be 10 minutes ago to 2 minutes ago. This is useful if you want to ignore the last 2 minutes of data.
- `IS BELOW 14` Defines the type of threshold and the threshold value. You can click on `IS BELOW` to change the type of threshold.
The query used in an alert rule cannot contain any template variables. Currently we only support `AND` and `OR` operators between conditions and they are executed serially.
For example, we have 3 conditions in the following order:
*condition:A(evaluates to: TRUE) OR condition:B(evaluates to: FALSE) AND condition:C(evaluates to: TRUE)*
so the result will be calculated as ((TRUE OR FALSE) AND TRUE) = TRUE.
We plan to add other condition types in the future, like `Other Alert`, where you can include the state
of another alert in your conditions, and `Time Of Day`.
#### Multiple Series
If a query returns multiple series then the aggregation function and threshold check will be evaluated for each series.
What Grafana does not do currently is track alert rule state **per series**. This has implications that are detailed
in the scenario below.
- Alert condition with query that returns 2 series: **server1** and **server2**
- **server1** series causes the alert rule to fire and switch to state `Alerting`
- Notifications are sent out with message: _load peaking (server1)_
- In a subsequence evaluation of the same alert rule the **server2** series also cause the alert rule to fire
- No new notifications are sent as the alert rule is already in state `Alerting`.
So as you can see from the above scenario Grafana will not send out notifications when other series cause the alert
to fire if the rule already is in state `Alerting`. To improve support for queries that return multiple series
we plan to track state **per series** in a future release.

### No Data / Null values
Below your conditions you can configure how the rule evaluation engine should handle queries that return no data or only null values.
No Data Option | Description
------------ | -------------
NoData | Set alert rule state to `NoData`
Alerting | Set alert rule state to `Alerting`
Keep Last State | Keep the current alert rule state, what ever it is.
### Execution errors or timeouts
The last option tells how to handle execution or timeout errors.
Error or timeout option | Description
------------ | -------------
Alerting | Set alert rule state to `Alerting`
Keep Last State | Keep the current alert rule state, what ever it is.
If you have an unreliable time series store from which queries sometime timeout or fail randomly you can set this option
to `Keep Last State` in order to basically ignore them.
## Notifications
In alert tab you can also specify alert rule notifications along with a detailed message 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
[notifications]({{< relref "notifications.md" >}}) guide for how to configure and setup notifications.
## Alert State History and Annotations
Alert state changes are recorded in the internal annotation table in Grafana's database. The state changes
are visualized as annotations in the alert rule's graph panel. You can also go into the `State history`
submenu in the alert tab to view and clear state history.
## Troubleshooting
{{< imgbox max-width="40%" img="/img/docs/v4/alert_test_rule.png" caption="Test Rule" >}}
First level of troubleshooting you can do is hit the **Test Rule** button. You will get result back that you can expand
to the point where you can see the raw data that was returned from your query.
Further troubleshooting can also be done by inspecting the grafana-server log. If it's not an error or for some reason
the log does not say anything you can enable debug logging for some relevant components. This is done
in Grafana's ini config file.
Example showing loggers that could be relevant when troubleshooting alerting.
```ini
[log]
filters = alerting.scheduler:debug \
alerting.engine:debug \
alerting.resultHandler:debug \
alerting.evalHandler:debug \
alerting.evalContext:debug \
alerting.extractor:debug \
alerting.notifier:debug \
alerting.notifier.slack:debug \
alerting.notifier.pagerduty:debug \
alerting.notifier.email:debug \
alerting.notifier.webhook:debug \
tsdb.graphite:debug \
tsdb.prometheus:debug \
tsdb.opentsdb:debug \
tsdb.influxdb:debug \
tsdb.elasticsearch:debug \
tsdb.elasticsearch.client:debug \
```
If you want to log raw query sent to your TSDB and raw response in log you also have to set grafana.ini option `app_mode` to
`development`.

{{< imgbox max-width="1000px" img="/img/docs/v4/alert_test_rule.png" caption="Test Rule" >}}
The first level of troubleshooting you can do is click **Test Rule**. You will get result back that you can expand to the point where you can see the raw data that was returned from your query.
Further troubleshooting can also be done by inspecting the grafana-server log. If it's not an error or for some reason the log does not say anything you can enable debug logging for some relevant components. This is done in Grafana's ini config file.
Example showing loggers that could be relevant when troubleshooting alerting.
```ini
[log]
filters = alerting.scheduler:debug \
alerting.engine:debug \
alerting.resultHandler:debug \
alerting.evalHandler:debug \
alerting.evalContext:debug \
alerting.extractor:debug \
alerting.notifier:debug \
alerting.notifier.slack:debug \
alerting.notifier.pagerduty:debug \
alerting.notifier.email:debug \
alerting.notifier.webhook:debug \
tsdb.graphite:debug \
tsdb.prometheus:debug \
tsdb.opentsdb:debug \
tsdb.influxdb:debug \
tsdb.elasticsearch:debug \
tsdb.elasticsearch.client:debug \
```
If you want to log raw query sent to your TSDB and raw response in log you also have to set grafana.ini option `app_mode` to `development`.

# View existing alert rules
Grafana stores individual alert rules in the panels where they are defined, but you can also view a list of all existing alert rules and their current state.
In the Grafana side bar, hover your cursor over the Alerting (bell) icon and then click **Alert Rules**. All configured alert rules are listed, along with their current state.
You can do several things while viewing alerts.
- **Filter alerts by name -** Type an alert name in the **Search alerts** field.
- **Filter alerts by state -** In **States**, select which alert states you want to see. All others will be hidden.
- **Pause or resume an alert -** Click the **Pause** or **Play** icon next to the alert to pause or resume evaluation. See [Pause an alert rule]({{< relref "pause-an-alert-rule.md" >}}) for more information.
- **Access alert rule settings -** Click the alert name or the **Edit alert rule** (gear) icon. Grafana opens the Alert tab of the panel where the alert rule is defined. This is helpful when an alert is firing but you don't know which panel it is defined in.

## Notification Reminders
Do you use Grafana alerting and have some notifications that are more important than others? Then it's possible to set reminders so that you continue to be alerted until the problem is fixed. This is done on the notification channel itself and will affect all alerts that use that channel.
For additional examples of why reminders might be useful for you, see [multiple series](/alerting/rules/#multiple-series).

Grafana v5.4 ships with a new alert rule setting named `For` which is great for removing false positives. If an alert rule has a configured `For` and the query violates the configured threshold it will first go from `OK` to `Pending`. Going from `OK` to `Pending` Grafana will not send any notifications. Once the alert rule has been firing for more than `For` duration, it will change to `Alerting` and send alert notifications. Typically, it's always a good idea to use this setting since it's often worse to get false positive than wait a few minutes before the alert notification triggers.
In the screenshot you can see an example timeline of an alert using the `For` setting. At ~16:04 the alert state changes to `Pending` and after 4 minutes it changes to `Alerting` which is when alert notifications are sent. Once the series falls back to normal the alert rule goes back to `OK`. [Learn more](/alerting/rules/#for).
