Maintaining optimal performance and ensuring seamless operations are crucial, especially in an industry such as manufacturing. Traditional systems like AS400 (IBM i) have long been the backbone of many manufacturing supply chains. However, integrating modern monitoring solutions such as Prometheus and Grafana can significantly enhance their efficiency and reliability. This blog explores the integration of these tools to transform AS400 environments, using Cloudera’s real-world implementation as a case study, and provides a comprehensive guide to adopting these modern monitoring solutions.

The Need for Modern AS400 Monitoring

Manufacturing companies often rely on AS400 systems for critical operations, including inventory management, production scheduling, and supply chain logistics. Despite their robustness, AS400 systems can benefit greatly from advanced monitoring solutions to:

  • Identify Performance Bottlenecks: Detect and resolve issues before they impact operations.
  • Enhance Visibility: Provide real-time insights into system performance and health.
  • Improve Decision-Making: Enable data-driven decisions with comprehensive metrics and dashboards.

Benefits of Integrating Prometheus and Grafana

Prometheus and Grafana offer a powerful combination for monitoring and visualizing the health and performance of AS400 systems. Some of the key benefits include:

  • Real-Time Monitoring: Monitor system metrics in real-time, allowing for immediate identification and resolution of issues.
  • Customizable Dashboards: Create highly customizable dashboards to visualize key performance indicators (KPIs) specific to your needs.
  • Scalable Architecture: Prometheus can handle a large volume of metrics efficiently, making it suitable for complex environments.
  • Alerting: Set up alerts to notify you of critical issues, enabling proactive management of your AS400 systems.

Case Study: Implementing Modern Monitoring in a Manufacturing Supply Chain

Background

Cloudera, a leader in enterprise data cloud management, faced challenges in monitoring their Cloudera DataFlow (CDF) deployments on AS400. The need for a scalable, real-time monitoring solution led them to adopt Prometheus and Grafana.

Implementation

  1. Setting Up Prometheus:
    • Configuring Endpoints: Cloudera configured HTTP(S) metrics endpoints in their CDF deployments to allow Prometheus to scrape metrics.
    • Creating Reporting Tasks: Using the Cloudera Data Platform (CDP) CLI, they created Prometheus reporting tasks to gather relevant metrics.
  2. Integrating Grafana:
    • Connecting to Prometheus: Grafana was connected to Prometheus to access the metrics collected.
    • Building Dashboards: Customized dashboards were created in Grafana to visualize key performance indicators (KPIs) and system health metrics.
  3. Real-Time Monitoring:
    • Cloudera utilized Grafana’s visualization capabilities to monitor metrics like data flow rates, system resource usage, and process health in real-time.

Key Benefits Realized

  • Enhanced Visibility: The real-time dashboards provided comprehensive visibility into the system’s performance, enabling proactive management.
  • Rapid Issue Resolution: With detailed metrics and alerts, Cloudera could quickly identify and resolve issues, minimizing downtime.
  • Scalability: The scalable nature of Prometheus allowed Cloudera to monitor an increasing number of metrics without compromising performance.
