# Monitor details

When you select a monitor from the [monitors list](/investigate/alerts/monitors#view-available-monitors),
Chronosphere Observability Platform opens the monitor's detail page. The detail page shows the
monitor's current alert state, a visualization of its query and triggered alerts over
time, and tools to investigate and act on those alerts. To query monitors or retrieve
alert history programmatically, see
[Monitor actions](/investigate/alerts/monitors/monitor-actions).

Click <Icon icon="link-2" /> **Copy URL** in the page header to copy a shareable URL
to your clipboard. Share it with teammates so they can view the same page directly.

## Review a monitor's status

The detail page leads with the monitor's current **Status**, which shows the number
of active alerts at each severity and whether any notifications are muted:

* **Passing** indicates that no series tracked by the monitor is actively triggering
  an alert.
* If any alerts are muted, a banner describes the muting. Click **More details**
  to see links to the active
  [muting rules](/investigate/alerts/muting-rules) that are silencing notifications.

The monitor's **Signal labels** appear next to the status indicator and indicates which
label values the monitor is currently tracking.

## Query results

The **Query results** section visualizes the time series data returned by the
monitor's query as a
[time series chart](/observe/dashboards/panels/time-series-chart).

Use the following controls to adjust the visualization:

* **All** / **Alerting** / **Critical**: Filter which series display on the chart by
  alert state.
* **<Icon icon="clock" /> [Time range selector](/navigate/time-ranges)**: Define the
  time span of data visualized in the chart.
* **Show thresholds**: Draw horizontal lines on the chart depicting the monitor's
  triggering thresholds.
* **Show query**: Display the query that populates the chart.
* **Open in explorer**: Open
  [Metrics Explorer](/investigate/querying/metrics/explorer) populated with the
  monitor's query.
* **Analyze anomaly (DDx)**: Right-click or long-press a series to perform
  [differential diagnosis](/investigate/analyze/differential-diagnosis) on it.

If the monitor uses
[signal grouping](/investigate/alerts/monitors/data-model#signals),
a **Group by signal** toggle appears to group series by their signal labels.

If you've [enabled change events](/observe/enable-events), an
**<Icon icon="layers" /> Events** control appears to configure which change events
overlay the chart. See [Change events](#change-events).

### Series legend

The series legend lists all metrics displayed in the chart, in either list or table
view. Both views show the label keys and values for each series. The **Alert status**
column shows each series' current alert state as a link. The link text is
**Critical**, **Warning**, **Muted**, **Resolved**, or **Passing**. Click the link
to open that series' [alert details](/investigate/alerts/alert-details) page. A series
might be **Muted** due to an active muting rule. For more information, see
[per-series muting status](/investigate/alerts/muting-rules#view-per-series-muting-status-on-a-monitor).

Filter and interact with the series legend:

* Use **Search Series** to filter the displayed series by text.
* Click a series color to isolate that line on the chart. Click again to clear the
  selection. Use `Control+`click (`Command+`click for macOS) to select multiple
  series.
* In a label column, hold the pointer over a cell to reveal the
  **<Icon icon="zoom-in" /> Add** or
  **<Icon icon="zoom-out" /> Remove label from filters** icons. These filters apply
  only when the time series includes *all* filtered labels.

## Active alerts list

The **Active alerts list** card shows all currently active alert instances for the
monitor. The card header displays the total count, for example
**Active alerts list (3)**. Each entry links to the corresponding
[alert details](/investigate/alerts/alert-details) page.

If the monitor has no active alerts, the card displays
`This monitor does not have any active alerts.`

## Alert history

The alert history log shows every alert generated by the monitor. To open it, click
**Alert history** in the actions menu. To query alert history programmatically, see
[Monitor actions](/investigate/alerts/monitors/monitor-actions).

Each entry shows the alert's timestamp, event type, and details including its
signals and notifiers.

* To sort, click a column header.
* To filter by event type, click the **Event types** dropdown and select the event
  types to display. Use the **Search** field in the dropdown to find a specific type.
* To toggle the signal scope, switch between the currently selected signal and all
  signals for the monitor.
* To view an alert's JSON payload, click the **>** icon on the alert's row. Click
  the <Icon icon="copy" /> icon to copy the payload.

<Note>
  There can be up to a five-minute delay between when an alert resolves and when
  Observability Platform sends the resolution notification.
</Note>

### Alert event payload

The JSON payload captures the values at the time the alert triggered. The payload
fields are primarily defined in the
[monitor data model](/investigate/alerts/monitors/data-model).

* `monitorSlug`: The monitor's unique
  [slug](/investigate/alerts/monitors/data-model#slug).
* `eventType`: The type of event triggered. Valid alert event types are:
  * Alert triggered
  * Alert resolved
  * Notification sent (alert triggered)
  * Notification failed (alert triggered)
  * Notification sent (alert resolved)
  * Notification failed (alert resolved)
  * Alert muted
  * Alert unmuted
* `createdAt`: The time the alert triggered.
* `signal`: See [signals](/investigate/alerts/monitors/data-model#signals). Contains
  one or more `name` and `value` entries.
* `details`: Contains `severity` as defined by the
  [notification policy](/investigate/alerts/notifications/policies) and
  [`notifier`](/investigate/alerts/notifications/notifiers).
  `notifier` values contain the notifier `name` and `slug`.

## Change events

If you've [enabled change events](/observe/enable-events), the query results chart
can overlay associated events using
[category icons](/observe/enable-events/use-events#categorize-change-events-intentionally).

To configure which change events appear:

1. Click **<Icon icon="layers" /> Events** to open the **Display events** panel.
2. Toggle **Show event markers** to show or hide event markers on the chart.
3. Toggle **Filter by entity** to limit events to those related to this monitor.
4. Use the **Code**, **Builder**, or **Event presets** mode to configure the
   change events query. **Event presets** appears only when presets are configured
   for the monitor.
5. Click **Save**.

For more information about change event details, see
[Change event details](/observe/enable-events/use-events#change-event-details).

## Monitor information

The monitor detail page includes a sidebar with reference information about the
monitor's configuration:

* **Monitor information**: The [collection](/administer/collections) assigned as its
  **Owner**, the **Team** responsible for it, and its **Notification policy**.
* **Datasource** and update **Interval**.
* **Additional information**: **Labels**, **Description**, and
  [templated links](/investigate/alerts/monitors/annotation-links) from the monitor's
  annotations, giving on-call engineers direct access to runbooks, related dashboards,
  and documentation.
