Change how Elasticsearch runs by providing your own user settings. User settings are appended to the
elasticsearch.yml configuration file for your cluster and provide custom configuration options. Elastic Cloud Enterprise supports many of the user settings for the version of Elasticsearch that your cluster is running.
Some settings that could break your cluster if set incorrectly are blacklisted, such as certain zen discovery and security settings. For examples of a few of the settings that are generally safe in cloud environments, see Additional Examples of Supported User Settings and Editing Your User Settings that can be enabled on our Elastic Cloud hosted offering.
To add user settings:
- Log into the Cloud UI.
On the Deployments page, select your deployment.
Narrow the list by name, ID, or choose from several other filters. To further define the list, use a combination of filters.
- From your deployment menu, go to the Edit page.
- At the bottom of the first Elasticsearch node, expand the User settings overrides caret.
- Update the user settings.
- Click Save changes.
The following examples configure email notifications to Gmail for a user that you specify. Which example you use depends on the version of Elasticsearch that your cluster is running.
For version 6.3 and later: See Configuring email actions.
For version 5.0 to 6.2: See Configuring email actions.
xpack.notification.email.account: gmail_account: profile: gmail smtp: auth: true starttls.enable: true host: smtp.gmail.com port: 587 user: <username> password: <password>
For versions before 5.0: Use Watcher to configure an email watch action. To learn more, see Configuring Email Actions.
watcher.actions.email.service.account: work: profile: gmail email_defaults: from: <email> smtp: auth: true starttls.enable: true host: smtp.gmail.com port: 587 user: <username> password: <password>
These example user settings cover only a subset of all user settings that you can include in the
elasticsearch.yml configuration file. To learn more about available settings, see Configuring Elasticsearch.
Examples of Elasticsearch user settings that you can specify:
Enables closing indices in Elasticsearch version 2.2 and later. You might enable this setting temporarily in order to change the analyzer configuration for an existing index. We strongly recommend leaving this set to
false(the default) otherwise. Closed indices are a data loss risk: If you close an index, it is not included in snapshots and you will not be able to restore the data. Similarly, closed indices are not included when you when you make cluster configuration changes, such as scaling to a different capacity, failover, and many other operations. Lastly, closed indices can lead to inaccurate disk space counts.
Closed indices are a data loss risk. Enable this setting only temporarily.
Whitelists the hosts that can be reindexed from remotely. Consists of a comma-delimited list of
host:portentries. Defaults to
- Enables regular expressions for the Painless scripting language.
- X-Pack alerting features (formerly Watcher)
Enables watches, including integration with Slack, HipChat, and PagerDuty. For example:
For version 6.3 and later:
For version 5.0 to 6.2:
For versions before 5.0:
Remember to check your user settings when performing a major version upgrade. For version 5.0 and later, the syntax for alerts is different when compared to earlier versions, for example.
- Disk-based shard allocation settings
