The topas command reports selected statistics about the activity on the local system. The command uses the curses library topsa display its output in a format suitable for viewing on an 80×25 character-based display or in a window of at least the same size on a graphical display.

The topas command requires the bos. If the topas command is invoked without flags, it axi as if invoked with the following command:. The default output, as shown below, consists of two fixed parts and a variable section.

The top two lines at the left of the display show the name of the system the topas command runs on, the date and time of the last observation, and the monitoring interval. The otpas part of the topas display can have one, two, three, four, or five subsections. If more than one subsection displays, they are always shown in the following order:. When the topas tpoas is started, it displays all subsections for which hot entities are monitored.

The following table provides the details for the subsections that the topas command displays:. This subsection displays one-line report summary of all the processor usage.

Pressing the c key only once turns this subsection off. If more than one processor exists, a list of processors is displayed by pressing the c key twice. Pressing the c key thrice displays a bar chart showing cumulative processor usage. The following fields are displayed by both formats:.

However, the list can be sorted by the other fields axi moving the cursor to the topsa of the desired column. This subsection shows a one-line report summary of the activity for all network interfaces.

Pressing the n key once turns off this subsection. Pressing the n key twice displays a list of active network interfaces.

The maximum number of interfaces displayed is the number of active interfaces being monitored, as specified by topaw the -n flag. A smaller number of interfaces are displayed if other subsections are also being displayed.

Both reports display the following fields:. When this subsection displays the list of hot network interfaces, the list is sorted by the BPS field.

Introduction to topas

Sorting is only valid for up to 16 network adapters. This subsection shows a one-line report summary of the activity for all physical disks. Pressing the d key turns once off qix subsection.

Pressing the d key again displays a list of active physical disks. The maximum number of physical disks displayed is ai number of active physical disks being monitored, as specified by using the -d flag. A smaller number of physical disks is displayed if other subsections are also being displayed. When this subsection displays the list of hot physical disks, the list is sorted by the BPS field.

Sorting is only valid for up to physical disks. This subsection shows a one-line report summary of the activity for all of the file systems. Pressing the f key once turns off this section.

Pressing the f key twice displays a list of active file systems. The maximum number of file systems that are displayed is the number of active file systems that are monitored when they are specified by using the -f flag. A smaller number of file systems are displayed if other subsections are also being displayed.

When this subsection displays the list of the file systems, the list is sorted by the BPS field. However, the list can be sorted by the other fields by moving the xix to the top of the target column.

The maximum number of WLM classes displayed is the number of hot WLM classes being monitored as specified with the -w flag. A smaller number of classes will be displayed if other subsections are also being displayed.

Pressing the w key turns off this subsection. The following fields are displayed for each class:. The workload partitions subsection replaces WLM subsection if invoked with the – flag. This subsection displays a list of hot workload partitions. The maximum number of workload partitions that are displayed is the number of hot WPAR that are monitored when they are specified with the -w – flag.

A smaller number of WPAR is displayed if other subsections are also being displayed. To turn off the workload partitions subsection, press the key. The following fields are displayed for each WPAR:. However, the list can be sorted by the other fields by moving the cursor to the top of the target column that you want to use to sort the list.

In topqs panel, the top section contains the same metrics that the Disks panel displays. The space bar key on the keyboard acts as a toggle for freezing the topas panel. If frozen, topas stops data collection and continues to display the data from the previous iteration.

You can move around the panel and sort the data based on the selected column. In frozen state, if you move between panels, some panels topae not display the data.

In this case, press the space bar key to unfreeze the topas panel. If the amount of data is more than the topas window size, then Page Up and Page Down keys are used to scroll though the data.

The data is sorted based on the selected column. This panel xix metrics similar to iax lparstat command for all the AIX partitions it can identify as belonging to the same hardware platform.

Dedicated and shared partitions are displayed in separate sections with appropriate metrics. The top section represents aggregated data from the partition set to show overall partition, memory, and processor activity. Remote enablement for this panel to collect from other partitions requires to use the latest updates to the perfagent. For earlier versions of AIXthe topas command also collects remote data from partitions that have the Performance Aide product perfagent. The topas -C command may not be able to locate partitions residing on other sub-nets.

The following metrics display in the initial cross-partition panel. Additional metrics with full descriptive labels can be displayed by using the key toggles identified in the Additional cross-partition panel subcommands section:. This panel displays the server adapter details in the top section and displays the target device and client disk details in the bottom of the section. To list the target devices and client disks belong to that adapter, select the adapter and press the f key.

This panel displays the statistics of all of the memory pools in the system. To display the partitions corresponding to that pool in the lower section of the panel, select a particular memory pool and press the f key. A cluster is a group of related gopas or nodes.

The Cluster Utilization view can either show utilization of an HA cluster or a user-defined cluster. The dedicated and shared partitions are displayed in separate sections with appropriate metrics. The following metrics are displayed in an initial cluster utilization panel. Additional metrics with full descriptive labels can be displayed using the key toggles identified in the Additional Cluster Utilization Panel Subcommands topic.

Disks topaas network adapters added after starting topas or any other SPMI consumer will not be reflected in topas. You must stop topas and all clients that use SPMI and then restart after the changes to disks and network adapters are made. The -D option provides Disk panel view where it reports disk service times, disk queuing metrics, and disk throughput.

Whenever -D option is started, it resets the disk minimum and maximum service time metrics during the first interval. Because the service time metrics are reset during first interval of -D option, the existing instance of -D option or some other consumer’s use of the disk service time metrics is affected. Displays the file system display.

When you specify the flag with the – flag or the subcommand, file system is shown in two windows. The top part of the display shows a list of active WPAR. This list can be sorted on any column. The display topsa file system service times, file system queuing metrics, and file system throughput. The following metrics are reported:. Specifies with the HotFS parameter the number of file system to be monitored.

This is also the maximum number of file system displayed when enough room is available. When this number exceeds the number of file system mounted, only the mounted file system is monitored and displayed.

If you do not specify the -f flag, the default value is two. If you specify a value of zero, the file system information is monitored.

If you specify the -i flag with the -R mode, the interval parameter becomes the recording interval for partition metrics. The default value for the interval parameter is seconds. Valid values are 10, 15, 30, 60,and seconds. The display topaz similar data to what is provided by the lssrad command.

While topas is running, it accepts 1-character subcommands. Each time the monitoring interval elapses, the program checks for one of the following subcommands and responds to the action requested.

When the topas Cross-partition panel is active, it accepts the following additional 1-character subcommands. Each topzs the monitoring interval elapses, the program checks for one of the following subcommands and responds to any requested action. When the topas Cluster Utilization panel is active, it accepts the following additional 1-character subcommands.
