Capacity Monitoring - Performance - Comparing Multiple Systems – IBM

You can compare systems and view detailed metrics for each system.

You can view the current resource consumption for all the systems managed by the Hardware Management Console (HMC) in the Resources Summary pane of the performance view, and then select specific systems for comparison.

To compare the performance details of specific managed systems, select from two to five systems in the systems inventory table and click Compare.

The comparison page with the following sections is displayed:

A metric selection drop-down menu with the metrics to compare:
- Core Usage.
- Memory Allocation.
- Network Traffic. You can further refine this to all traffic, single root I/O virtualization (SRIOV) Traffic, or Host Ethernet Adapter (HEA) Traffic.
- Storage Traffic.
- Power Usage.
Export CSV control. Click Export CSV to export the data that is displayed.
A tabular display of the current metric performance for the systems being compared.
The date range for the comparison.
A stacked graph of the metric performance during the date range for the systems being compared.
A table of metric performance during the date range for the systems being compared.

Core Usage

The Current Core Usage section displays the following information for each compared system:

System name.
MTM serial number.
The number of partitions in the compared system. The number of partitions indicate the total number of partitions and Virtual I/O Servers (VIOS) present in the managed system. A managed system can be connected to more than one HMC.
The state.
The HMC to which the compared system is connected.
The usage percentage.
The number of allocated cores.
The number of available cores.
The number of inactive cores.
The number of installed cores.

Date Range

The Date Range section shows the date range for the comparison. By default, the date range is the last 8 hours. You can modify the date range by using the calendar displayed below the Date Range field, or select the available date range options: Last 8 Hours, Last 24 Hours, Last Week, Last Month, or Last Year.

Stacked Graph

The Stacked Graph section displays the graph of the core usage for the chosen date range. The Y-axis represents the total core usage and the X-axis represents the date and time range. Each system is shown in a different color for easy comparison. If the system does not have data available for that date range, the system is greyed out in the legend section and a “No data available” message is displayed in hover help.

Note: Missing data for a system is indicated in the graph with a message in the legend section listing the name of system that has missing data. To view missing data for that particular system in the graph, deselect all other systems.

Data ranges that are not common to all compared systems are shown as zero. For samples that are not present for a particular date range, the total core usage is calculated as 0 for that date and time for the particular system.

Select or deselect the compared systems to include or remove them from the graph.
Move your cursor through the graph to see the Core Usage value for different date ranges in the graph.
Click and drag a specific date range to view the average, minimum and maximum core usage for the selected date range. Click Zoom to view the core usage for the specific date range in the graph. After you click Zoom, the graph changes and displays the core usage only for the specific date range.

The Update Table option is enabled only when you select a date range in the graph. Click Update Table to view the updated data of the core usage for a specific date range in the Performance History table.
