Aspectow AppMon 3.0: Real-time Dashboard Guide

Dashboard Components

1. Intelligent Tab Navigation

• Domain Tabs: Logically separate and manage server groups or clusters. Indicators on each tab show connection status in real-time.
• Instance Tabs: Switch between individual application instances within a domain. Data is seamlessly synchronized during transitions, allowing you to immediately view the state of the previous instance.

2. Server Resource and Performance Monitoring

• Real-time Resource Metrics:
  • Heap Status: Displays current JVM heap memory usage and maximums to detect GC status and memory leaks.
  • Undertow Thread Pool: Monitors active threads against the total pool size to assess concurrent processing load.
• Activity Status (Real-time Counts): Provides three key metrics for each server instance:
  1. Active Activity: The number of real-time activities being processed simultaneously.
  2. Current Period Count: The number of activities inflowed during the current 5-minute aggregation window (displayed as a relative value like +14).
  3. Cumulative Total: The total number of activities accumulated since the server started (p.cumulative).
• 5-Minute Aggregation Management: A timer (e.g., 233/300) indicates the progress of the 300-second data aggregation. At 300/300, the data is stored on the server, reflected in the analysis charts, and the cycle resets.
• Summary Statistics: Periodically stored data is permanently recorded on the server, allowing users to compare and analyze historical trends and current status.

3. Canvas-based Traffic Visualization (Traffic Flow)

All user requests (Request/Activity) are visualized as ‘Bullets’ flying from left to right. It uses a high-performance Delta-time based engine to maintain smooth animation even under heavy load.

• Kinetic Visualization Logic:
  • Speed vs. Response Time: As response time (elapsedTime) increases, the bullet speed is decelerated by up to 60%. This serves as a visual indicator of system congestion.
  • Persistence: The time a bullet stays at the ‘finish line’ before fading is proportional to the actual server response time (elapsedTime + 200ms). Heavier requests linger longer to draw the operator’s attention.
  • Hotspot & Hot Core: Requests from heavy users with an activity intensity exceeding 0.3 generate a white Hot Core at the center of the bullet for instant identification.
• Color Coding by Status:
  • Green: Normal requests processed at standard speeds.
  • Yellow: Warning requests where response time starts to lag (500ms or more).
  • Red: Requests that encountered an error during processing.
• Data Synchronization: All activity data is aggregated in 5-minute intervals, stored on the server, and immediately reflected in the analysis charts.

4. Session State and User Activity Management

• Real-time Session List: Provides a list of session information for currently connected users.
  • Country Identification: Displays country flags based on the session’s IP to understand user distribution.
  • Activity Counts: Shows real-time activity counts for each session to monitor heavy users.
• Session Statistics: Summary cards for Active, Peak, and Created/Expired session flows.

5. Multi-dimensional Analysis Charts

• Activities & Sessions Chart: Visualizes trends in real-time request volume and session changes.
• Flexible Time Units: Switch between 5-minute (Default), hourly, daily, monthly, and yearly views to analyze everything from short-term spikes to long-term patterns.

6. Professional Log Console and History Exploration

A high-performance console that streams server logs in real-time.

• Real-time Tailing & Control: Supports low-latency log output with features like Pause, Clear, and Full-screen mode.
• View Previous Logs (Reverse Infinite Scroll): A ‘Load Previous Logs’ button activates when the user scrolls to the top of the log box. This allows for seamless historical context exploration while the real-time stream continues.
