When you select a monitor from the monitors list, 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. Click 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 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. Use the following controls to adjust the visualization:
  • All / Alerting / Critical: Filter which series display on the chart by alert state.
  • Time range selector: 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 populated with the monitor’s query.
  • Analyze anomaly (DDx): Right-click or long-press a series to perform differential diagnosis on it.
If the monitor uses signal grouping, a Group by signal toggle appears to group series by their signal labels. If you’ve enabled change events, an Events control appears to configure which change events overlay the chart. See 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 page. A series might be Muted due to an active muting rule. For more information, see per-series muting status. 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 Add or 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 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. 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 to copy the payload.
There can be up to a five-minute delay between when an alert resolves and when Observability Platform sends the resolution notification.

​
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.
  • monitorSlug: The monitor’s unique 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. Contains one or more name and value entries.
  • details: Contains severity as defined by the notification policy and notifier. notifier values contain the notifier name and slug.

​
Change events

If you’ve enabled change events, the query results chart can overlay associated events using category icons. To configure which change events appear:
  1. Click 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.

​
Monitor information

The monitor detail page includes a sidebar with reference information about the monitor’s configuration:
  • Monitor information: The collection assigned as its Owner, the Team responsible for it, and its notification Policy.
  • Datasource and update Interval.
  • Additional information: Labels, Description, and custom Links from the monitor’s annotations, giving on-call engineers direct access to runbooks, related dashboards, and documentation.
