Prometheus示例警报配置未验证

处提供的示例配置

groups:
- name: example
  rules:
  - alert: HighErrorRate
    expr: job:request_latency_seconds:mean5m{job="myjob"} > 0.5
    for: 10m
    labels:
      severity: page
    annotations:
      summary: High request latency

但是，如果我尝试验证此文件：

promtool check-rules rules al.yaml 
Checking rules
  FAILED: cannot get file info

Checking al.yaml
  FAILED: parse error at line 2, char 2: unexpected <op:-> in record statement, expected "="

我要去哪里错了？这种语法过时了吗？
