# Set the default telemetry interval

## Overview

The telemetry interval specifies the time window for which events, metrics and traces are available in the StackState perspectives. It runs from left to right on the timeline at the bottom of the StackState UI. By default, the telemetry interval active when opening a [view](https://archivedocs.stackstate.com/5.1/use/stackstate-ui/views/about_views) or [explore mode](https://archivedocs.stackstate.com/5.1/use/stackstate-ui/explore_mode) is set to a relative time period, showing telemetry data from the last hour. If required, you can configure StackState to use a different default telemetry interval.

## Customise the default telemetry interval

You can configure the default telemetry interval used in StackState with the parameter `defaultTimeRange`. The configured value will then be applied automatically when a view or explore mode is opened.

{% hint style="info" %}
A telemetry interval specified by a user in the StackState UI will override the default telemetry interval and will be applied to each subsequent view opened.
{% endhint %}

The default telemetry interval can be set to any of the following values:

* `LAST_5_MINUTES`
* `LAST_15_MINUTES`
* `LAST_30_MINUTES`
* `LAST_1_HOUR` (default value)
* `LAST_3_HOURS`
* `LAST_6_HOURS`
* `LAST_12_HOURS`
* `LAST_24_HOURS`
* `LAST_2_DAYS`
* `LAST_7_DAYS`
* `LAST_30_DAYS`

Any other value will be ignored and converted to the default value (`LAST_1_HOUR`).

To set a custom default telemetry interval, add the following to the `values.yaml` file used to deploy StackState:

```yaml
stackstate:
  components:
    api:
      config: |
         stackstate.webUIConfig.defaultTimeRange = "LAST_15_MINUTES"

```

{% endtab %}

{% tab title="Linux" %}
To set a custom default telemetry interval, update the parameter `stackstate.webUIConfig.defaultTimeRange` in the file `/etc/application_stackstate.conf`.

```yaml
stackstate {
  webUIConfig {
    defaultTimeRange = "LAST_15_MINUTES"
  }
}
```

{% endtab %}
{% endtabs %}
