is this a valid prometheus exposition?

[Vishwanath N]

hi all - is below a valid prometheus exposition for a gauge -  pls note that except time stamps and values for the datapoints the label and label values are the same . 

 if this is a valid gauge, what will be the behavior when honor_timestamps = true ?

 # TYPE my_gauge gauge
my_gauge 1 1687479732169
my_gauge 0 1687479737169
my_gauge 1 1687479742169

thanks .

Hi Vishwanath,

This is not valid for the text exposition format, since the same time series is repeated multiple times. See https://prometheus.io/docs/instrumenting/exposition_formats/#text-based-format - "Each line must have a unique combination of a metric name and labels. Otherwise, the ingestion behavior is undefined.".

Other interfaces for writing data into Prometheus, like the remote write receiver (https://prometheus.io/docs/prometheus/latest/querying/api/#remote-write-receiver), support sending more than one sample per series at once, but whether that's the right interface to use for your use case depends on the details of what you're trying to do.

Regards,

Julius
