使用prometheus-agent，config.toml [global.labels] 失效 about categraf HOT 5 CLOSED

prometheus-agent 是单独的agent，现在不支持config.toml的配置

from categraf.

如果不使用prometheus-agent，直接使用prometheus插件，会将指标进行压缩，压缩后的指标传到prometheus上面后，指标丢失具体情况如下：
我监控http接口的使用情况得到如下原始指标
http_server_requests_seconds{applications="gateway-service",exception="None",method="GET",outcome="SUCCESS",service="pay",status="200",uri="/timersSleep100",quantile="0.5",} 0.0
http_server_requests_seconds{applications="gateway-service",exception="None",method="GET",outcome="SUCCESS",service="pay",status="200",uri="/timersSleep100",quantile="0.75",} 0.0

http_server_requests_seconds_sum{applications="gateway-service",exception="None",method="GET",outcome="SUCCESS",service="pay",status="200",uri="/timersSleep100",} 0.6214917

当我使用categraf拉取上述指标，通过http接口传给prometheus后，http_server_requests_seconds 响应时间百分位指标丢失，并且http_server_requests_seconds指标中的tag quantile加到了http_server_requests_seconds_count，http_server_requests_seconds_sum，http_server_requests_seconds_bucket中

from categraf.

但使用prometheus-agent就不会出现上述情况，但是使用prometheus-agent后不支持config.toml的配置

from categraf.

prometheus-agent 也支持全局label，在prometheus-agent对应的yaml中配置

把完整的指标 和 input.prometheus 采集的完整指标 都发一下。
