Crate sysinfo

sysinfo is a crate used to get a system’s information.

Before any attempt to read the different structs’ information, you need to update them to get up-to-date information.

Examples

use sysinfo::{ProcessExt, SystemExt};

let mut system = sysinfo::System::new_all();

// First we update all information of our system struct.
system.refresh_all();

// Now let's print every process' id and name:
for (pid, proc_) in system.get_processes() {
    println!("{}:{} => status: {:?}", pid, proc_.name(), proc_.status());
}

// Then let's print the temperature of the different components:
for component in system.get_components() {
    println!("{:?}", component);
}

// And then all disks' information:
for disk in system.get_disks() {
    println!("{:?}", disk);
}

// And finally the RAM and SWAP information:
println!("total memory: {} KB", system.get_total_memory());
println!("used memory : {} KB", system.get_used_memory());
println!("total swap  : {} KB", system.get_total_swap());
println!("used swap   : {} KB", system.get_used_swap());

// Display system information:
println!("System name:             {:?}", system.get_name());
println!("System kernel version:   {:?}", system.get_kernel_version());
println!("System OS version:       {:?}", system.get_os_version());
println!("System host name:        {:?}", system.get_host_name());
