Turbostat irq. SMI The number of System Management Interrupts serviced CPU during the measurement interval. The first method is to supply a command, which is forked and statistics are printed upon its completion. We would like to show you a description here but the site won’t allow us. The first method is to supply a \fBcommand\fP, which is forked and statistics are printed in one-shot upon its completion. IRQ) show the sum 117 across all CPUs in the system. IRQ The number of interrupts serviced by that CPU during the measurement interval. Use case 1: Display statistics IRQ The number of interrupts serviced by that CPU during the measurement interval. . (override interval with "-i sec" option, or specify a command for turbostat to fork). Without any parameters, turbostat displays statistics ever 5 seconds. Columns that dump raw MSR val‐ 119 ues simply show 0 in the summary. Turbostat is useful for identifying servers that are inefficient in terms of power usage or idle time. turbostat parses /proc/interrupts to generate this summary. The 5-second interval can be changed using the --interval option. IRQ The number of interrupts serviced by that CPU during the measurement interval. There are two ways to invoke turbostat. The system total line is the sum of interrupts serviced across all CPUs. NAME ¶ turbostat - Report processor frequency and idle statistics SYNOPSIS ¶ turbostat [Options] command turbostat [Options] [--interval seconds] DESCRIPTION ¶ turbostat reports processor topology, frequency, idle power-state statistics, temperature and power on X86 processors. turbostat reports processor topology, frequency, idle power-state statistics, temperature and power on X86 processors. It displays the interrupt request (IRQ) number, the number of that type of interrupt request handled by each processor in the system, the type of interrupt sent, and a comma-separated list of devices that respond to the listed interrupt request. It provides insights into the processor’s topology, frequency, temperature, power, and idle states, making it an essential tool for system administrators and performance analysts aiming to understand CPU performance and thermal behavior. Columns that show a percentage show the 118 average across all CPUs in the system. It also helps to identify the rate of system management interrupts (SMIs) occurring on the system. Dec 1, 2025 · turbostat是一款内核工具包组件，用于监控CPU状态并帮助管理员识别服务器异常情况，如过度耗电等问题。本文介绍了turbostat的使用方法及各项指标含义。 IRQ The number of interrupts serviced by that CPU during the measurement interval. It can also be used to verify the effects of power management tuning. The first method is to supply a command, which is forked and statistics Dec 17, 2024 · Turbostat is a powerful command-line utility used to monitor and report detailed statistics about a computer’s processor. The turbostat [Options] command turbostat [Options] [--interval seconds] DESCRIPTION turbostat reports processor topology, frequency, idle power-state statistics, temperature and power on X86 processors. The second method is to omit the command, and turbostat displays statistics every 5 seconds interval. Columns that count items (eg. turbostat 由 kernel-tools 软件包提供。它在 Intel ® 64 处理器中报告处理器拓扑、频率、空闲电源状态统计、温度和电源使用情况。 Turbostat 可用于识别在功耗或空闲时间方面效率低下的服务器。它还有助于确定系统上发生的系统管理中断 (SMI)的速度。.
