Grafana直方图显示错误的值(数据源:Prometheus)

Question

我使用Grafana 4.3.2和Prometheus 2.0作为数据源.我正试图在Grafana上显示Prometheus直方图.我从Prometheus检索的值如下:

http_request_duration_seconds_bucket{<other_labels>, le="+Inf"}     146
http_request_duration_seconds_bucket{<other_labels>, le="0.005"}    33
http_request_duration_seconds_bucket{<other_labels>, le="0.01"}     61
http_request_duration_seconds_bucket{<other_labels>, le="0.025"}    90
http_request_duration_seconds_bucket{<other_labels>, le="0.05"}     98
http_request_duration_seconds_bucket{<other_labels>, le="0.1"}      108
http_request_duration_seconds_bucket{<other_labels>, le="0.25"}     131
http_request_duration_seconds_bucket{<other_labels>, le="0.5"}      141
http_request_duration_seconds_bucket{<other_labels>, le="1"}        146
http_request_duration_seconds_bucket{<other_labels>, le="10"}       146
http_request_duration_seconds_bucket{<other_labels>, le="2.5"}      146
http_request_duration_seconds_bucket{<other_labels>, le="5"}        146

所以我期望看到的是12个桶,其值在右侧指定.但是,Grafana显示完全不同的值,如下所示:

有什么我想念的,或者Grafana根本不支持Prometheus直方图(丢弃"le"标签)？

您需要将图例格式化程序设置为“{{le}}”
