Grafana not getting the data from prometheus

Grafana Configuration
1

Grafana is getting empty result from Prometheus. But for the same “metric” prometheus responds with data.
There is not connectivity issue as am getting proper result for other metrics.

Query - aws_elb_httpcode_backend_2_xx_sum

Grafana Request - https://XYZ/api/v1/query_range?query=aws_elb_httpcode_backend_2_xx_sum&start=1519028103&end=1519031008&step=30
Response - {“status”:“success”,“data”:{“resultType”:“matrix”,“result”:[]}}

I have tried rate() sum() around the query but always get empty result.

Grafana - 4.6.3
Prometheus - 2.1.0

Ideas:

  • Make sure there’s data for the time span you’re looking at. That one got me good yesterday.
  • Maybe try to simplify the math - don’t do rate() or sum().

I had this today. For me the issue was resolved by setting the time parameter explicitly. Also ensuring it was not more precise than a whole second.
