In our synthetic monitoring tool, the monitors index lists your synthetic monitors, and gives you a snapshot of each monitor's performance over the last 24 hours. Select a specific monitor to view a [**Summary** page](https://docs.newrelic.com/docs/synthetics/new-relic-synthetics/dashboards/synthetics-overview-dashboard-view-monitors-performance) and get deeper insights about its performance. Or, [filter the list](#search-monitors) to quickly compare the performance of similar monitors.

## View the monitors index [#viewing]

To see a list of your synthetic monitors, go to **[one.newrelic.com > Synthetic monitoring](https://one.newrelic.com/synthetics-nerdlets)**.

## Understand monitor metrics [#understanding]

Use the monitors index to access your monitors and view a snapshot of monitor performance. The index includes the following metrics:

-   [**Alert status**](https://docs.newrelic.com/docs/alerts/new-relic-alerts/configuring-alert-policies/identify-entities-without-alert-policies): Indicates the status of any alerts on the monitor:
    -   Green: No open alert events
    -   Red: Critical alert event in progress
    -   Grey: No alert conditions defined with alerts
-   **Monitor status**: Indicates a status has been applied to the monitor, such as **Mute** or **Disabled**.
-   **Success rate**: The percentage of monitor checks that end in success. A multi-step monitor that does not complete all steps is considered a failure.
-   **[Locations failing](https://docs.newrelic.com/docs/synthetics/new-relic-synthetics/using-monitors/adding-editing-monitors#setting-location)**: The number of locations that have failed during the given timeframe.
-   **[Period](https://docs.newrelic.com/docs/synthetics/new-relic-synthetics/using-monitors/adding-editing-monitors#setting-frequency)**: How often the monitor checks run.
-   **[Monitor type](https://docs.newrelic.com/docs/synthetics/new-relic-synthetics/using-monitors/add-edit-monitors#setting-type)**: The selected monitor type.

## Use index functions [#using]

The monitors index supports the following features:

| **If you want to...**   | **Do this...**                                                                                                                                                                                                                                                                                                       |

| Sort the monitor list   | Select a column label to sort the list based on that [metric](#understanding). Select the label again to change the sort order from ascending to descending.                                                                                                                                                         |
| Filter the monitor list | Type your keyword in the search box to filter by name, [tags](https://docs.newrelic.com/docs/new-relic-one/use-new-relic-one/core-concepts/tagging-use-tags-organize-group-what-you-monitor), or [entitiy](https://docs.newrelic.com/docs/new-relic-one/use-new-relic-one/core-concepts/what-entity-new-relic) type. |
| Add to favorites        | To favorite a monitor, select the **star _star_ icon** icon. Favorite monitors appear at the top of the monitor list. To remove a monitor from your favorites, select the **star** icon again.                                                                                                                       |
