Deleting labels in Prometheus

I'm using Prometheus to do some monitoring but I can't seem to find a way to delete labels I no longer want. I tried using the DELETE /api/v1/series endpoint but it doesn't remove it from the dropdown list on the main Prometheus Graph page. Is there a way to remove them from the dropdown without restarting from scratch?

Thanks

Prometheus doesn't provide the ability to delete particular labels, because this may result to duplicate time series with identical labelsets. For example, suppose Prometheus contains the following time series:

http_requests_total{instance="host1",job="foobar"}
http_requests_total{instance="host2",job="foobar"}

If instance label is removed, then these two time series will become identical:

http_requests_total{job="foobar"}
http_requests_total{job="foobar"}

Now neither Prometheus nor user can differentiate these two time series.

Prometheus provides only the API for deleting time series matching the given series selector - see these docs for details.

This happens to me also, try to include the metric name when querying for labels' values like this:

    label_values(node_load1, instance)

If you delete every relevant timeseries then it should no longer be returned. If this is not the case, please file a bug.
