Monitor metrics
To effectively monitor system performance, you must decide which aspects of system performance you want to monitor. IBM® Navigator for i offers various performance measurements, which are known as metrics, to help you pinpoint different aspects of system performance.
When you configure a monitor, you can use any metric, a group of metrics, or all the metrics from the list to be included in your monitor. Metric types that you can use in your monitor include the following.
Metric groups | Metric description |
---|---|
CPU Utilization | The percentage of available processing unit time that is consumed
by jobs on your system. Choose from the following types of CPU Utilization
metrics for use in your monitors: ![]()
![]() |
Interactive Response Time (Average and Maximum) | The response time that interactive jobs experience on your system. |
Transaction Rate (Interactive) | The number of transactions per second completed on your system
by ![]() ![]() |
Batch Logical Database I/O | The average number of logical database input/output (I/O) operations
that are currently performed by batch jobs ![]() ![]() |

If you need more help, click the Help button on the Create New System Monitor-Metrics page. After you become familiar with the IBM Navigator for i metrics, which metrics you select depend on the information needs of your computing environment. After you select metrics that target the information you are trying to see, you are ready to view and change detailed metric information for each metric you selected for your monitor.
