Wiki: Need to add parameter in labels

What is recommended way for adding Parameter in metrics… ?

I mean, Currently we have: invocation_by_type_created{item_type="hey"} 1.5603457069620097e+09 Which can be achieved by:

@metrics.counter('invocation_by_type', 'Number of invocations by type',
         labels={'item_type': "hey"})
def echo_status(status):
    return 'Status: %s' % status, status

Now, We need to have some timedelta included in output metrics, something like: invocation_by_type_created{item_type="hey", timedelta=52} 1.5603457069620097e+09

which is ofcause the function execution time…

You can have more than one labels, and they accept functions or lambdas for values that are evaluated in the request context. See usage at https://github.com/rycus86/prometheus_flask_exporter/blob/master/README.md#usage

Is this what you’re after?
