Below are examples of metrics and measures  that are common when looking at IT infrastructure, middleware, and server performance.

Why People Use These Metrics

These metrics are useful when:

• Considering service level metrics for infrastructure hosting providers and applications.
• What to charge clients based on usage of infrastructure services.
• Quality, stability, and capacity of infrastructure services

Metrics

• Disk space utilization (we want to check utilization and growth over time). Check space utilization on specific partitions like ones for log files and critical application server files
• Number of middleware related incidents (errors, problems, etc.) and source of incidents (monitoring, clients, users, etc)
• Throughput of requests
• Up time
• Input / Output – bytes received/transmitted per second
• Usage thresholds for various performance measures related to CPU, memory, disk, network, failed transactions
• CPU, memory, disk, network, failed transactions (%) over time
