# Configure individual browser monitors
<note>
  This is only relevant for monitors that are created and managed using a [Synthetics project](/elastic/docs-builder/docs/3028/solutions/observability/synthetics/get-started#observability-synthetics-get-started-synthetics-project). For more information on configuring browser monitors added in the UI, refer to [Create monitors in the Synthetics UI](https://www.elastic.co/elastic/docs-builder/docs/3028/solutions/observability/synthetics/create-monitors-ui).
</note>

After [writing synthetic journeys](https://www.elastic.co/elastic/docs-builder/docs/3028/solutions/observability/synthetics/write-synthetic-test), you can use `monitor.use` to configure the browser monitors that will run your tests.
You’ll need to set a few configuration options:
- **Give your monitor a name.** Provide a human readable name and a unique ID for the monitor. This will appear in Kibana or your Observability Serverless project where you can view and manage monitors after they’re created.
- **Set the schedule.** Specify the interval at which your tests will run.
- **Specify where the monitors should run.** You can run monitors on Elastic’s global managed testing infrastructure or [create a Private Location](https://www.elastic.co/elastic/docs-builder/docs/3028/solutions/observability/synthetics/monitor-resources-on-private-networks) to run monitors from your own premises.
- <applies-to>Elastic Stack: Generally available since 9.1</applies-to> **Choose which spaces the monitor is visible in.** (Kibana only) You can make the monitor visible in one or more [spaces](https://www.elastic.co/elastic/docs-builder/docs/3028/deploy-manage/manage-spaces), or use `'*'` for all spaces. Options set in `monitor.use()` override the project-level `spaces` setting in your [Synthetics project config](/elastic/docs-builder/docs/3028/solutions/observability/synthetics/configure-projects#synthetics-configuration-monitor).
- **Set other options as needed.** There are several other options you can set to customize your implementation including params, tags, screenshot options, throttling options, and more.

Configure each monitor directly in your `journey` code using `monitor.use`. The `monitor` API allows you to set unique options for each journey’s monitor directly through code. For example:
```js
import { journey, step, monitor, expect } from '@elastic/synthetics';

journey('Ensure placeholder is correct', ({ page, params }) => {
  monitor.use({
    id: 'example-monitor',
    schedule: 10,
    spaces: ['default', 'team-a'],
    throttling: {
      download: 10,
      upload: 5,
      latency: 100,
    },
  });
  step('Load the demo page', async () => {
    await page.goto('https://elastic.github.io/synthetics-demo/');
  });
  step('Assert placeholder text', async () => {
    const placeholderValue = await page.getAttribute(
      'input.new-todo',
      'placeholder'
    );
    expect(placeholderValue).toBe('What needs to be done?');
  });
});
```

For each journey, you can specify its `schedule`, the `locations` in which it runs, <applies-to>Elastic Stack: Generally available since 9.1</applies-to> `spaces` (applies to Stack deployments only), and other options. When an option is not set in `monitor.use()`, Synthetics uses the default from the global configuration file. Options set in `monitor.use()` take precedence over the project-level config—for example, `spaces` here overrides the global `monitor.spaces` setting.
