Getting "was collected before with the same name and label values"

[KK]

I am trying to write my own custom exporter and getting the following error message. Would like to know as to why i am getting this message  and how do solve the problem ?

was collected before with the same name and label values

One thing to note is the value for a given label keeps changing.

Any thoughts on this would be very helpful.

Can you post the metrics from your exporter? Like by using curl?

Followed these steps

1) Declared []string for labelNames as below

          LabelNames = []string{

                                                   "src_ip",

                                                   "dst_ip",

                                                   "proto",

        }

2) Created a gauge as below

c.connections = typedDesc{prometheus.NewDesc(

                prometheus.BuildFQName(namespace, subsystem, "connections"),

                "The current active connections by local and remote address.",

                labelNames, nil,

        ), prometheus.GaugeValue}

3) Filled info for the labels

       for _, flowStats := range flowsStats {

                labelValues := []string{

                        flowStats.SrcIP,

                        flowStats.DstIP,

                        flowStats.Proto,

                }

                ch <- c.connections.mustNewConstMetric(float64(1) , labelValues...)

See these in console.

Is flowsStats a unique set of (src, dest, proto) entries?

If there are duplicate entries, that will cause this problem.

Can you post the output of `curl {exporter ip}:{port}`?

You are right. There were duplicate entries. The problem went away the duplicate entries were address.

Appreciate your help here.
