Current Architecture

Job Scheduler: A powerful web application for scheduling and managing jobs. Users can easily create, modify, and delete jobs, as well as monitor the state of batch executors. The logging function enables real-time tracking and analysis of system execution status, providing key insights. If a job execution fails, alerts can be configured to send immediate notifications. Additionally, job dependencies can be defined to automate complex workflows and scheduling.

Task Executor: Provides the essential runtime environment for job execution. Optimized for Java development environments, it enables developers to implement flexible batch processes. Each Task Handler executes specific job units and is distributed across multiple instances to ensure high availability. This system allows efficient job distribution and management when workload increases or the system scales. Task Executor helps developers manage complex data processing tasks effectively.

Target Architecture

Vue.js: The Vue.js framework is applied to develop the client interface, implementing a responsive UI.

Prometheus & Grafana: Prometheus collects data for system monitoring, and Grafana visualizes it.

ELK Stack: Elasticsearch stores log data, Logstash collects logs, and Kibana visualizes the data for log management and troubleshooting.

Kubernetes: Automates the deployment, scaling, and management of containerized applications.

Docker: Enhances scalability and system stability through outscaling and load balancing.

Job Status: Provides a real-time overview of the system by categorizing all registered jobs into running, scheduled, completed, and disabled.

Processing History: Shows the trend of job processing over a specific period. Different colors visualize the job statuses such as success, failure, and running over time.

System Health: Allows real-time monitoring of key components such as application, database, disk, and external servers along with server uptime.

System Status: Provides real-time usage rates of key system resources such as CPU, memory, and disk, helping to detect potential bottlenecks or overloads in advance.

General Jobs

Job List: Displays all registered jobs in a list view, allowing you to quickly see the job name, schedule type, handler, and status.

Schedule Type: Identifies whether each job is manually triggered (NONE) or scheduled automatically (CRON), showing its execution cycle.

Handler / GLUE Type: Shows the handler class name and execution method (e.g., BEAN) connected to each job for better understanding of execution logic.

Status Control Switch: Allows toggling the standby state (on/off) for each job to quickly control its activation.

Search & Filter: Easily locate and manage jobs using group selection, keyword search, and status-based filters.

Handler Management

Handler List: Displays all registered handlers in a list format along with their associated job names and descriptions.

Title / Batch Name: Describes the purpose or testing intent of the handler, and shows the batch name to identify the execution environment.

Search & Filter: Quickly find the desired handler using name search and job group filters.

Last Modified: Shows when the handler was last updated, helping to track recent changes.

Job Execution Status

Job List Panel: View execution status, handler name, and author for each job, and select a job to see detailed execution information.

Execution Summary: Summarizes average CPU and memory usage, recent success rate, average execution time, and last execution time of the selected job.

Execution History Tab: Check start/end times, duration (in seconds), and result (success/failure) of each execution to identify issues quickly.

Performance/Error/Log Tabs: View detailed performance metrics, error history, server logs, and handler logs related to job execution through separate tabs.

User Activity Audit

Audit List: Displays user ID, name, action type (e.g., view, page visit), action details, API path, execution time, and IP address in a tabular format.

Search Filter: Quickly retrieve logs using date range, action type, keyword search, and group filters.

View Parameters: Allows detailed analysis of user requests by showing parameters passed with each request.

Audit Trail: Logs key system access events including login, enabling security auditing, anomaly detection, and user accountability tracking.

Server Resource Report

Handler List: Displays all registered handlers in a list format along with their associated job names and descriptions.

Title / Batch Name: Describes the purpose or testing intent of the handler, and shows the batch name to identify the execution environment.

Search & Filter: Quickly find the desired handler using name search and job group filters.

Last Modified: Shows when the handler was last updated, helping to track recent changes.
