# Configure the Elasticsearch data source
|
|||
|
|
|||
|
Grafana ships with built-in support for Elasticsearch.
|
|||
|
You can make many types of queries to visualize logs or metrics stored in Elasticsearch, and annotate graphs with log events stored in Elasticsearch.
|
|||
|
|
|||
|
For general documentation on querying data sources in Grafana, see [Query and transform data]({{< relref "../../panels-visualizations/query-transform-data" >}}).
|
|||
|
|
|||
|
For instructions on how to add a data source to Grafana, refer to the [administration documentation]({{< relref "../../administration/data-source-management/" >}}).
|
|||
|
Only users with the organization administrator role can add data sources.
|
|||
|
Administrators can also [configure the data source via YAML]({{< relref "#provision-the-data-source" >}}) with Grafana's provisioning system.
|
|||
|
|
|||
|
## Configure the data source
|
|||
|
|
|||
|
To add the Elasticsearch data source, complete the following steps:
|
|||
|
|
|||
|
1. Click **Connections** in the left-side menu.
|
|||
|
1. Under **Connections**, click **Add new connection**.
|
|||
|
1. Enter `Elasticsearch` in the search bar.
|
|||
|
1. Select **Elasticsearch data source**.
|
|||
|
1. Click **Create a Elasticsearch data source** in the upper right.
|
|||
|
|
|||
|
You will be taken to the **Settings** tab where you will set up your Elasticsearch configuration.
|
|||
|
|
|||
|
## Configuration options
|
|||
|
|
|||
|
The following is a list of configuration options for Elasticsearch.
|
|||
|
|
|||
|
The first option to configure is the name of your connection:
|
|||
|
|
|||
|
- **Name** - The data source name. This is how you refer to the data source in panels and queries. Examples: elastic-1, elasticsearch_metrics.
|
|||
|
|
|||
|
- **Default** - Toggle to select as the default data source option. When you go to a dashboard panel or Explore, this will be the default selected data source.
|
|||
|
|
|||
|
### HTTP section
|
|||
|
|
|||
|
- **URL** - The URL of your Elasticsearch server. If your Elasticsearch server is local, use `<http://localhost:9200>`. If it is on a server within a network, this is the URL with port where you are running Elasticsearch. Example: `<http://elasticsearch.example.orgname:9200>`.
|
|||
|
|
|||
|
- **Allowed cookies** - Specify cookies by name that should be forwarded to the data source. The Grafana proxy deletes all forwarded cookies by default.
|
|||
|
|
|||
|
- **Timeout** - The HTTP request timeout. This must be in seconds. There is no default, so this setting is up to you.
|
|||
|
|
|||
|
### Auth section
|
|||
|
|
|||
|
There are several authentication methods you can choose in the Authentication section.
|
|||
|
|
|||
|
{{% admonition type="note" %}}
|
|||
|
Use TLS (Transport Layer Security) for an additional layer of security when working with Elasticsearch. For information on setting up TLS encryption with Elasticsearch see [Configure TLS](https://www.elastic.co/guide/en/elasticsearch/reference/8.8/configuring-tls.html#configuring-tls). You must add TLS settings to your Elasticsearch configuration file **prior** to setting these options in Grafana.
|
|||
|
{{% /admonition %}}
|
|||
|
|
|||
|
- **Basic authentication** - The most common authentication method. Use your `data source` user name and `data source` password to connect.
|
|||
|
|
|||
|
- **With credentials** - Toggle to enable credentials such as cookies or auth headers to be sent with cross-site requests.
|
|||
|
|
|||
|
- **TLS client authentication** - Toggle to use client authentication. When enabled, add the `Server name`, `Client cert` and `Client key`. The client provides a certificate that is validated by the server to establish the client's trusted identity. The client key encrypts the data between client and server.
|
|||
|
|
|||
|
- **With CA cert** - Toggle to authenticate with a CA certificate. Follow the instructions of the CA (Certificate Authority) to download the certificate file.
|
|||
|
|
|||
|
- **Skip TLS verify** - Toggle on to bypass TLS certificate validation.
|
|||
|
|
|||
|
- **Forward OAuth identity** - Forward the OAuth access token (and the OIDC ID token if available) of the user querying the data source.
|
|||
|
|
|||
|
### Custom HTTP headers
|
|||
|
|
|||
|
- **Header** - Add a custom header. This allows custom headers to be passed based on the needs of your Elasticsearch instance.
|
|||
|
|
|||
|
- **Value** - The value of the header.
|
|||
|
|
|||
|
### Elasticsearch details
|
|||
|
|
|||
|
The following settings are specific to the Elasticsearch data source.
|
|||
|
|
|||
|
- **Index name** - Use the index settings to specify a default for the `time field` and your Elasticsearch index's name. You can use a time pattern, such as `YYYY.MM.DD`, or a wildcard for the index name.
|
|||
|
|
|||
|
- **Pattern** - Select the matching pattern if using one in your index name. Options include:
|
|||
|
|
|||
|
- no pattern
|
|||
|
- hourly
|
|||
|
- daily
|
|||
|
- weekly
|
|||
|
- monthly
|
|||
|
- yearly
|
|||
|
|
|||
|
- **Time field name** - Name of the time field. The default value is @timestamp. You can enter a different name.
|
|||
|
|
|||
|
- **Max concurrent shard requests** - Sets the number of shards being queried at the same time. The default is `5`. For more information on shards see [Elasticsearch's documentation](https://www.elastic.co/guide/en/elasticsearch/reference/8.9/scalability.html#scalability).
|
|||
|
|
|||
|
- **Min time interval** - Defines a lower limit for the auto group-by time interval. This value **must** be formatted as a number followed by a valid time identifier:
|
|||
|
|
|||
|
| Identifier | Description |
|
|||
|
| ---------- | ----------- |
|
|||
|
| `y` | year |
|
|||
|
| `M` | month |
|
|||
|
| `w` | week |
|
|||
|
| `d` | day |
|
|||
|
| `h` | hour |
|
|||
|
| `m` | minute |
|
|||
|
| `s` | second |
|
|||
|
| `ms` | millisecond |
|
|||
|
|
|||
|
We recommend setting this value to match your Elasticsearch write frequency.
|
|||
|
For example, set this to `1m` if Elasticsearch writes data every minute.
|
|||
|
|
|||
|
You can also override this setting in a dashboard panel under its data source options. The default is `10s`.
|
|||
|
|
|||
|
- **X-Pack enabled** - Toggle to enable `X-Pack`-specific features and options, which provide the [query editor]({{< relref "./query-editor/" >}}) with additional aggregations, such as `Rate` and `Top Metrics`.
|
|||
|
|
|||
|
- **Include frozen indices** - Toggle on when the `X-Pack enabled` setting is active. You can configure Grafana to include [frozen indices](https://www.elastic.co/guide/en/elasticsearch/reference/7.13/frozen-indices.html) when performing search requests.
|
|||
|
|
|||
|
{{% admonition type="note" %}}
|
|||
|
Frozen indices are [deprecated in Elasticsearch](https://www.elastic.co/guide/en/elasticsearch/reference/7.17/frozen-indices.html) since v7.14.

|
### Logs
|
|||
|
|
|||
|
In this section you can configure which fields the data source uses for log messages and log levels.
|
|||
|
|
|||
|
- **Message field name:** - Grabs the actual log message from the default source.
|
|||
|
|
|||
|
- **Level field name:** - Name of the field with log level/severity information. When a level label is specified, the value of this label is used to determine the log level and update the color of each log line accordingly. If the log doesn’t have a specified level label, we try to determine if its content matches any of the [supported expressions](/docs/grafana/latest/explore/logs-integration/#log-level). The first match always determines the log level. If Grafana cannot infer a log-level field, it will be visualized with an unknown log level.
|
|||
|
|
|||
|
### Data links
|
|||
|
|
|||
|
Data links create a link from a specified field that can be accessed in Explore's logs view. You can add multiple data links
|
|||
|
|
|||
|
Each data link configuration consists of:
|
|||
|
|
|||
|
- **Field** - Sets the name of the field used by the data link.
|
|||
|
|
|||
|
- **URL/query** - Sets the full link URL if the link is external. If the link is internal, this input serves as a query for the target data source.<br/>In both cases, you can interpolate the value from the field with the `${__value.raw }` macro.
|
|||
|
|
|||
|
- **URL Label** (Optional) - Sets a custom display label for the link. The link label defaults to the full external URL or name of the linked internal data source and is overridden by this setting.
|
|||
|
|
|||
|
- **Internal link** - Toggle on to set an internal link. For an internal link, you can select the target data source with a data source selector. This supports only tracing data sources.
