Feature Updates

Incidents

New incidents provide integrated fault handling support. When a monitor detects an anomaly, it automatically generates a fault incident, merges duplicate alerts, and notifies the responsible party based on the on-duty schedule. If unresolved within a timeout period, notifications are escalated according to predefined policies. On the fault detail page, you can view related monitoring metrics, error logs, call traces, and other information in one place. It supports status updates and team collaboration, with a complete audit trail of all actions. This feature helps teams standardize fault handling procedures and improve response efficiency and process transparency.

In the Billing Logic for the Fault Center: Each time an escalation policy is triggered, 100 task invocations are recorded when a notification is sent.

Errors

The “Error Center” feature is now available! It automatically aggregates errors from APM, RUM, and Logs, using intelligent grouping to converge similar problems into unified Issues for tracking. Before use, you need to configure delivery rules to define the monitoring scope. You can then view error summaries, statuses, and trends in the list view, or dive into the details page to analyze complete stack traces, related traces, and user sessions. All errors support status management and team collaboration, enabling end-to-end management from discovery to resolution.

Concurrently, the “Error Count” billing metric has been added, counting the daily number of newly created Issue records, including those generated by the Error Center.

Open API

  1. Resource Directory: Added support for creating, editing, and deleting resource group information.
  2. Added direct editing of account status (On Duty, On Leave).

Metrics Analysis

  1. Added Top N series and maximum return data points options, allowing you to specify the number of top or bottom data series (20/50/100/500) to return for each query after sorting.
  2. Added support for clicking on chart data points and selecting from a dropdown menu to view similar trending metrics, drill down for analysis, or access other related views.

Infrastructure

  1. Hosts:
    • Added list filtering support via the df_mute field.
    • For hosts globally muted via Open API or rules, a “Muted” indicator will now be displayed in the host list.
  2. Resource Directory: Added a “Service Inventory” list entry.

Scenarios

  1. Dashboards: Added an Associate Monitor button for quick access to monitors linked with the dashboard.
  2. Charts: Added unified sequence identifiers to all chart alias configurations and intuitive hover interactions to visualize the correspondence when configuring multiple query lines.

APM

Profiling: If a Profile file size exceeds 20MB, online parsing is not supported. A user-friendly prompt has been added, recommending the use of specialized analysis tools for viewing.

LLM Monitoring

The statistical dimension for application metrics has been adjusted: from being based on individual Spans to being based on complete Traces.

Logs

Explorer: Optimized the display logic for the message field after selecting “Reset to Default Fields” in the display options.

Management

SSO Management: Optimized the SSO login flow. Users must first select an identity provider via email and complete authentication. Upon success, they can then view accessible workspaces in a protected state to prevent permission information leakage.

Feature Updates

Chart

Advanced Settings: Added a "Sampling Prediction" toggle. When enabled, the system first calculates the amount of data after filtering. Sampling is only triggered when the data volume reaches the sampling threshold, and is performed proportionally based on the estimated data size. If the filtered data volume is below the lower limit, sampling will not be activated.

Logging

Log index names now support the hyphen - naming format.

Management

  1. Data Forwarding: When selecting a log data source to configure forwarding rules, support for selecting filter conditions for native direct-write indexes is now available.

  2. Member Management: A new "Show only enabled permissions" toggle has been added.

  3. Preferences: A new APM default landing page option has been added, allowing customization of the default page (Trace, Service, Analysis Dashboard) opened after clicking the left-side APM navigation bar.

Time Control

The time control functionality has been enhanced: When a discrepancy of more than 1 minute is detected between the user's local device time and the server time, the system will automatically display a warning prompt. This helps prevent data query range errors caused by inaccurate local time.

Feature Updates

Scenes

Added Data List: Compatible with the original "Log Stream Graph" and "Object List" charts, which will be deprecated in the future.

  • The system provides commonly used default display columns for each data source; you can directly select fields to display in the upper data list via dropdown.
  • Common Configuration: Added "Alias" configuration; when Logs is selected as the data source, added "Display" configuration.
