Alerting set up
editAlerting set up
editKibana alerting features are automatically enabled, but might require some additional configuration.
Prerequisites
editIf you are using an on-premises Elastic Stack deployment:
-
In the
kibana.yml
configuration file, add thexpack.encryptedSavedObjects.encryptionKey
setting. -
For emails to have a footer with a link back to Kibana, set the
server.publicBaseUrl
configuration setting.
If you are using an on-premises Elastic Stack deployment with security:
- If you are unable to access Kibana alerting features, ensure that you have not explicitly disabled API keys.
The alerting framework uses queries that require the
search.allow_expensive_queries
setting to be true
. See the scripts
documentation.
Production considerations and scaling guidance
editWhen relying on alerting and actions as mission critical services, make sure you follow the alerting production considerations.
For more information on the scalability of alerting features, go to Scaling guidance.
Security
editTo use alerting features in a Kibana app, you must have the appropriate feature privileges:
Give full access to manage alerts, connectors, and rules in Stack Management
editKibana privileges
-
All
for the Management > Stack Rules feature. -
All
for the Management > Rules Settings feature. -
All
for the Management > Actions and Connectors feature.
The Actions and Connectors feature privilege is required to manage connectors.
To add rule actions and test connectors, you require only Read
privileges.
By default, All
privileges include authority to run Endpoint Security connectors (such as SentinelOne and CrowdStrike) unless you customize the sub-feature privileges.
Likewise, you can customize the Rules Settings sub-feature privileges related to flapping detection settings.
To create a rule that uses the Cases connector, you must also have All
privileges for the Cases feature.
The rule type also affects the privileges that are required.
For example, to create or edit machine learning rules, you must have all
privileges for the Analytics > Machine Learning feature.
For Stack Monitoring rules, you must have the monitoring_user
role.
For Observability rules, you must have all
privileges for the appropriate Observability features.
For Security rules, refer to Detections prerequisites and requirements.
Give view-only access to alerts, connectors, and rules in Stack Management
editKibana privileges
-
Read
for the Management > Stack Rules feature. -
Read
for the Management > Rules Settings feature. -
Read
for the Management > Actions and Connectors feature.
The rule type also affects the privileges that are required.
For example, to view machine learning rules, you must have read
privileges for the Analytics > Machine Learning feature.
For Stack Monitoring rules, you must have the monitoring_user
role.
For Observability rules, you must have read
privileges for the appropriate Observability features.
For Security rules, refer to Detections prerequisites and requirements.
Give view-only access to alerts in Discover or Dashboards
editKibana privileges
-
Read
index privileges for the.alerts-*
system indices.
Revoke all access to alerts, connectors, and rules in Stack Management, Discover, or Dashboards
editKibana privileges
-
None
for the Management > Stack Rules feature. -
None
for the Management > Rules Settings feature. -
None
for the Management > Actions and Connectors feature. -
No index privileges for the
.alerts-*
system indices.

API keys
editRules are authorized using an API key. Its credentials are used to run all background tasks associated with the rule, including condition checks like Elasticsearch queries and triggered actions.
When you create a rule in Kibana, an API key is created that captures a snapshot of your privileges. Likewise when you update a rule, the API key is updated with a snapshot of your privileges at the time of the edit.
When you disable a rule, it retains the associated API key which is reused when the rule is enabled. If the API key is missing when you enable the rule, a new key is generated that has your current security privileges. When you import a rule, you must enable it before you can use it and a new API key is generated at that time.
You can generate a new API key at any time in Stack Management > Rules or in the rule details page by selecting Update API key in the actions menu.
If you manage your rules by using Kibana APIs, they support support both key- and token-based authentication as described in Authentication. To use key-based authentication, create API keys and use them in the header of your API calls as described in API Keys. To use token-based authentication, provide a username and password; an API key that matches the current privileges of the user is created automatically. In both cases, the API key is subsequently associated with the rule and used when it runs.
If a rule requires certain privileges, such as index privileges, to run and a user without those privileges updates the rule, the rule will no longer function. Conversely, if a user with greater or administrator privileges modifies the rule, it will begin running with increased privileges. The same behavior occurs when you change the API key in the header of your API calls.
Restrict actions
editFor security reasons you may wish to limit the extent to which Kibana can connect to external services. You can use Action settings to disable certain Connectors and allowlist the hostnames that Kibana can connect with.
Space isolation
editRules and connectors are isolated to the Kibana space in which they were created. A rule or connector created in one space will not be visible in another.
Cross-cluster search
editIf you want to use alerting rules with cross-cluster search, you must configure privileges for CCS and Kibana. Refer to Remote clusters.
