SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

IBM i performance data is scattered across multiple collections and views, making it challenging for operators to quickly assess system health and spot bottlenecks.

Core Features & Use Cases

Consolidated visibility into Collection Services configuration, temporary storage usage, disk I/O statistics, and memory pool performance via IBM i SQL services.
Ideal for capacity planning, troubleshooting storage growth, and identifying hot spots in I/O and memory pressure.
Example: a sysadmin reviews current collection intervals and per-job temp storage to forecast capacity and adjust monitoring settings.

Quick Start

Retrieve and view performance metrics using the built-in ibmi CLI tools to fetch current configuration, storage usage, and disk I/O stats.

FAQPage Schema

How do I monitor IBM i performance metrics for troubleshooting system health?▼

Monitor IBM i performance metrics by retrieving data from QSYS2 SQL services like COLLECTION_SERVICES_INFO and SYSTMPSTG. This consolidates visibility into temporary storage usage, disk I/O statistics, and memory pool performance to help operators spot bottlenecks.

What is the best way to check temporary storage usage by jobs on IBM i?▼

Check temporary storage usage by querying the SYSTMPSTG SQL service. This approach provides consolidated visibility into per-job storage consumption, making it ideal for troubleshooting unexpected storage growth on IBM i systems.

Can I view disk I/O statistics and memory pool performance using IBM i SQL services?▼

View disk I/O statistics and memory pool performance by querying SYSDISKSTAT and MEMORY_POOL SQL services. These views provide tool wrappers to filter and report metrics, identifying hot spots in I/O and memory pressure.

How do I retrieve current Collection Services configuration for capacity planning on IBM i?▼

Retrieve current Collection Services configuration by querying QSYS2.COLLECTION_SERVICES_INFO. Operators can review collection intervals to forecast capacity needs and adjust monitoring settings for ongoing system performance tracking.

Does this performance monitoring approach require any external dependencies?▼

This performance monitoring approach requires no external dependencies. It relies entirely on built-in IBM i SQL services and ibmi-cli tools to fetch current configuration, storage usage, and disk I/O stats.
