我的刮擦间隔和评估间隔彼此相距遥远(15s对4m)。当我向端点提供指标时,我发现预期每4m评估规则一次。但是,我不明白的是,它不会评估最近4分钟内提供的所有指标的规则。我很难理解两个时钟(抓取和评估)的功能。另外,关于此的文档非常稀疏。任何指针都会有很大帮助。我毫不犹豫地将抓取时间和评估时间更改为每个15秒。但是我需要了解将时钟分开的后果。
# my global config
global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 4m # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).
# Alertmanager configuration
alerting:
alertmanagers:
- static_configs:
- targets:
- testmanager:9093
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
- "/etc/prometheus/xyz_rule.yml"
- "/etc/prometheus/pqr_rule.yml"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: 'prometheus'
# metrics_path defaults to '/metrics'
metrics_path: /v1/metrics/xyz
# scheme defaults to 'http'.
static_configs:
- targets: ['test:7070']

这两个过程是独立的,PromQL和记录规则都不知道您的抓取间隔是多少。因此,无论指定的评估时间间隔是多少,指定的任何规则在给定时间评估时都将以相同的方式进行评估,并且结果相同。
为简便起见,最好将两个间隔设置为相同,因此我建议在这里将两者都设置为15s。
