Can metric name start with numbers?

[chenlujjj]

Seems it's not allowed when querying in Grafana:

But according to the doc:

Metric names and label names may contain any unicode letter
It should be allowed.

@chenlujjj you have to query it as {__name__="3ds.metric.count"}. Otherwise, the parser assumes you're entering a time interval or a number.

Got it, thanks @hagen1778

Reviewing the MetricsQL code I would think in the case of numbers you could use the escape character \ before the number Ex: \3ds.metrics.count
