How many CPUs do I have Solaris?

To find the number of physical CPUs on any system use the -p option with psrinfo command. The -p option may not work with solaris 9 and below. In that case use the kstat command to find the physical CPUs. Now psrinfo or psrinfo -v would display all the logical/virtual CPUs.

What is Solaris CPU?

Solaris is the computer operating system that Sun Microsystems provides for its family of Scalable Processor Architecture-based processors as well as for Intel-based processors. Sun emphasizes the system’s availability (meaning it seldom crashes), its large number of features, and its Internet-oriented design.

How do I see CPU usage in Solaris 11?

Use the sar -u command to display CPU utilization statistics. The sar command without any options is equivalent to the sar -u command. At any given moment, the processor is either busy or idle. When busy, the processor is in either user mode or system mode.

Where is Solaris hardware info?

Use the psrinfo -p command to display the total number of physical processors on a system. Use the psrinfo -pv command to display information about each physical processor on a system, and the virtual processor that is associated with each physical processor.

Where is physical and logical CPU in Linux?

You can use one of the following command to find the number of physical CPU cores including all cores on Linux:

  1. lscpu command.
  2. cat /proc/cpuinfo.
  3. top or htop command.
  4. nproc command.
  5. hwinfo command.
  6. dmidecode -t processor command.
  7. getconf _NPROCESSORS_ONLN command.

How do you find the number of physical CPUs CPU cores and logical CPUs?

Find out how many cores your processor has

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Select the Performance tab to see how many cores and logical processors your PC has.

Why is Solaris dead?

As had been rumored for a while, Oracle effectively killed Solaris on Friday. It is a cut so deep as to be fatal: the core Solaris engineering organization lost on the order of 90% of its people, including essentially all management.

Is Solaris still being used?

There is no doubt Solaris is less used as a desktop / generic OS but it is definitely still used and actively developed in specialized/high-end servers, have a look to engineered systems like Oracle SuperCluster and also Oracle ZFS storage appliances. There are two projects which could be considered “Solaris”.

How do I read a SAR file?

Report Sar Data Using Start Time (sar -s) When you view historic sar data from the /var/log/sa/saXX file using “sar -f” option, it displays all the sar data for that specific day starting from 12:00 a.m for that day. Using “-s hh:mi:ss” option, you can specify the start time.

How do I see CPU usage on Linux?

How To Check CPU Usage from Linux Command Line

  1. top Command to View Linux CPU Load. Open a terminal window and enter the following: top.
  2. mpstat Command to Display CPU Activity.
  3. sar Command to Show CPU Utilization.
  4. iostat Command for Average Usage.
  5. Nmon Monitoring Tool.
  6. Graphical Utility Option.

How much memory does Solaris use?

On Solaris, you can use the command prtconf to determine how much physical memory the computer has. This command (located in /usr/sbin) displays the total amount of memory for the computer in megabytes. 1.

Which command can be used to show OS name?

To display the name of the operating system, use the uname command.

How to display virtual processor information in Solaris?

Using the psrinfo -pv command will list all the physical processors that are in the system, as well as the virtual processors that are associated with each physical processor. The default output of the psrinfo command continues to display the virtual processor information for a system. For more information, see the psrinfo (1M) man page.

How to identify Solaris processor cores in unixarena?

For hardware inventory, we may need to provide the Processor details like number installed physical processors , number core per processor on Solaris SPARC and X86 system.

How to display the current time in Solaris?

To display the current date and time according to your system clock, use the date command. The following example shows sample output from the date command. The psrinfo command has been modified to provide information about physical processors, in addition to information about virtual processors.

What does the psrinfo command do in Solaris?

The psrinfo command has been modified to provide information about physical processors, in addition to information about virtual processors. This enhanced functionality has been added to identify chip multithreading (CMT) features. The new -p option reports the total number of physical processors that are in a system.
