Initialize metrics with labels to 0 #641
Description
In #139 metrics without labels are initialized to 0 when created. Would it be possible to have a function that can initialize metrics with labels to 0 for a known set of label values? Something like:
const summary = new promClient.Summary({
name: 'http_request_duration_seconds',
labelNames: labels
});
summary.init({"response_status": "success"});
summary.init({"response_status": "error"});
