parse error in expression in alert rule

[pznamensky]

What did you do?
Pasted correct PromQL expression into alerting rule
The rule looks like:

groups:
- name: MySweetGroup
  rules:
  - alert: MySweetRule
    expr: max(allocation_memory)  by (exported_job) / max(allocation_memory_limit) by (exported_job) > 0.8
    for: 5m
    labels:
      severity: info
    annotations:
      summary: Oops

What did you expect to see?
Working alert

What did you see instead? Under which circumstances?
Prometheus error:

caller=manager.go:479 component="rule manager" msg="loading groups failed" err="group \"MySweetGroup\", rule 0, \"MySweetRule\": could not parse expression: parse error at char 52: unexpected <by> in aggregation, expected \")\""

• Prometheus version:

That parses for me fine with 2.1.0, are you sure that's the file you're using?

[pznamensky]

Oh, I'm sorry.
I checked the rule twice but didn't find any errors.
Indeed real expression is very long and I missed right bracket.
My bad.

[brian-brazil]

No problem, glad you sorted it out.
