When alert rules trigger across your application, the resulting events can accumulate quickly, making it difficult to identify patterns or prioritize responses. Event analysis in Managed Service for OpenTelemetry provides real-time filtering, aggregation, and trend visualization for alert events, so you can diagnose issues by scenario rather than sifting through individual notifications.
Prerequisites
Before you begin, make sure you have:
An alert rule configured for your application. For more information, see Create an alert rule
Key concepts
| Term | Description |
|---|---|
| Alert event | A record generated when an alert rule's conditions are met. Each event captures the trigger time, severity level, and contextual details. |
| Filter condition | A criterion applied to narrow down displayed events, such as severity level, time range, or event status. |
| Aggregation dimension | A grouping attribute (for example, service name or alert level) used to summarize event data in charts and tables. |
View and filter alert events
Log on to the . In the left-side navigation pane, click Applications.
On the Applications page, select a region in the top navigation bar, then click the name of your application.
In the top navigation bar, click Events.
The Events page contains three sections:
| Section | Purpose |
|---|---|
| Quick Filter | Combine filter conditions and aggregation dimensions to narrow the displayed charts and event list. Select severity levels, time ranges, or custom dimensions to focus on the events that matter most. |
| Alert Event Trend | A time-series chart showing the distribution of events by alert level over a selected period. Use this to spot spikes or recurring patterns. |
| Event list | A table listing each event with its event name, feature field, event status, number of events, and associated alerts. |
Inspect event details
In the event list, click an event name to open a detail panel with three tabs:
| Tab | What it shows |
|---|---|
| Details | Full context of the alert event, including trigger conditions, severity, and affected resources. |
| History | A timeline of past state changes for this event, from initial trigger through each status transition. |
| Related events | Other events associated with this alert, helping you identify correlated failures or broader incident patterns. |
View associated alerts
In the event list, click the link in the Associated Alerts column to navigate to the details of the related alert rules and their current state.
Manually clear an alert event
After you resolve an issue, clear the corresponding alert event to keep your event list accurate:
In the event list, find the target event.
In the Actions column, click Manually Clear Alert.
The event status changes to Cleared.
