# Search telemetry
|
|
|
|
You can use search telemetry to analyze search request performance by success or failure in OpenSearch Dashboards. OpenSearch stores telemetry data in the `.kibana_1` index.
|
|
|
|
Because there are thousands of concurrent search requests from OpenSearch Dashboards, the heavy traffic can cause significant load in an OpenSearch cluster.
|
|
|
|
OpenSearch clusters perform better with search telemetry turned off.

## Turning on search telemetry
|
|
|
|
Search usage telemetry is turned off by default. To turn it on, you need to set `data.search.usageTelemetry.enabled` to `true` in the `opensearch_dashboards.yml` file.
|
|
|
|
You can find the [OpenSearch Dashboards YAML file](https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/config/opensearch_dashboards.yml) in the opensearch-project repository on GitHub.
|
|
|
|
Turning on telemetry in the `opensearch_dashboards.yml` file overrides the default search telemetry setting of `false` in the [Data plugin configuration file](https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/src/plugins/data/config.ts).

### Turning search telemetry on or off
|
|
|
|
The following table shows the `data.search.usageTelemetry.enabled` values you can set in `opensearch_dashboards.yml` to turn search telemetry on or off.
|
|
|
|
OpenSearch Dashboards YAML value | Search telemetry status: on or off
|
|
:--- | :---
|
|
`true` | On
|
|
`false` | Off
|
|
`none` | Off
|
|
|
|
#### Sample opensearch_dashboards.yml with telemetry enabled
|
|
|
|
This OpenSearch Dashboards YAML file excerpt shows the telemetry setting set to `true` to turn on search telemetry:
|
|
|
|
```json
|
|
# Set the value of this setting to false to suppress
|
|
# search usage telemetry to reduce the load of the OpenSearch cluster.
|
|
data.search.usageTelemetry.enabled: true
|
|
``` |
