Python Client library: Metric with same name but different label

[Vishnu B]

I am writing a node_exporter text_file export using python client library.

I have metrics with the same metric name but different label values like below

TPL{dc="tlv1",instance="core2.tlv1",job="cisco_ipsla",link_id="PL2_31.0",region="sjc2"} 19.0

TPL{dc="ash1",instance="core1.ash1",job="cisco_ipsla",link_id="PL2_100.0",region="sjc2"} 119.0 

when I try to write this I get the below error.

```ValueError: Duplicated timeseries in CollectorRegistry: {'TPL'}```

Below is my script

registry = CollectorRegistry()

for query in queries:

for val in query:

metric_name = list(val.keys())[1]

key = list(val["metric"].keys())

g = Gauge(metric_name, 'weekly report of link status', val["metric"].keys(), registry=registry)

g.labels(**val["metric"]).set(val[metric_name][1])

write_to_textfile('/tmp/link.prom', registry)

how do I expose metric with the same name but different label value using python client_library

Hi Vishnu,

Did you have any luck in fixing this issue? Any solution?

I'm having a similar problem and still couldn't find an answer.
