Problem when pushing using golang client - invalid metric name about prom-aggregation-gateway

[bboreham]

I looked at the package; you need to call .Format(expfmt.FmtText) to meet the expectations of this program (documented here).

I filed prometheus/client_golang#824 for the inconsistency.

I’ve not looked at the Pusher package, but “foo-job” is invalid per the spec - minus sign is not allowed.

I am trying out this project, and I am getting a similar error. Same code works with the prometheus push gateway.

Could not push metrics to push gateway. unexpected status code 400 while pushing to http://push-gateway/metrics/job/region_metrics/assets/regions: text format parsing error in line 1: invalid metric name

if err := push.New("http://push-gateway/", "region_metrics").
        Collector(metric).
        Grouping("assets", "regions").
        Push(); err != nil {
        log.Printf("metrics.%v - Could not push metrics to push gateway. %v", fn, err)
}

Indeed, that fixes the error.
