Prometheus监控概述

Prometheus是一款开源的监控和警报工具，广泛应用于各种规模的系统监控，它通过收集指标数据、存储和查询数据，实现对系统的实时监控和故障预警，在Prometheus中，百分比作为一种重要的指标表示方式，常用于描述系统资源利用率、性能指标等。

在Prometheus中，百分比通常以指标名称后加“%”符号的形式表示，表示CPU使用率的指标可以写作`cpu_usage{job="my_job", instance="my_instance"}{state="idle"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{state="unknown"}{mode="user"}{mode="system"}{mode="nice"}{mode="idle"}{mode="iowait"}{mode="softirq"}{mode="steal"}{mode="guest"}{mode="guest_nice"}{mode="total"}{state="running"}{state="suspended"}{stat
