![]() PCI devices may include usb ports, graphics cards, network adapters, etc. You can use the -v option to generate detailed information about each USB device. The lsusb command is used to report information about USB controllers and all the devices that are connected to them. If you want to view all block devices on your system then include the -a option. lsblk command is used to report information about block devices as follows. ![]() How to Collect Linux Block Device Informationīlock devices are storage devices such as hard disks, flash drives, etc. To view information about your CPU, use the lscpu command as it shows information about your CPU architecture such as the number of CPUs, cores, CPU family model, CPU caches, threads, etc from sysfs and /proc/cpuinfo. ~ $ sudo lshw -html > lshw.html Generate Linux Hardware Information in HTML 3.

The cpuinfo utility is available for both Intel microprocessors and non-Intel microprocessors, but it may provide only partial information about non-Intel microprocessors.Īn example of the cpuinfo output: $ cpuinfo -gdcs = Processor composition = ![]() The architecture information is available on systems based on the Intel® 64 architecture. If the node has no processors, the node is not shown. Processors - a list of processors in this node.Table shows the following information about NUMA nodes: Microprocessor feature flags indicate what features the microprocessor supports. Microprocessor signature hexadecimal fields (Intel platform notation) show signature values: Processors - a list of processor groups enclosed in the parentheses those share this cache or no sharing otherwise.A group of processors enclosed in brackets belongs to one core.Ĭache sharing by logical processors shows information of sizes and processors groups, which share particular cache level. This list order directly corresponds to the core list. Processors Id - list of processors that belong to this package.Cores Id - list of core identifiers that belong to this package.Package Id - physical package identifier.Each entry contains the information on packages, cores, and logical processors. Node decomposition table shows the node contents. Package Id - unique package identifier within a node.Core Id - unique core identifier within a package.Thread Id - unique processor identifier within a core.Logical processors identification table identifies threads, cores, and packages of each logical processor accordingly. core and threads numbers on the node and within each package.the number of packages/sockets on the node.General information about single cluster node shows: Each option controls a specific part of the output data. ![]()
