We are seeing an impossible value for our http_total{http_version="1"} metric. The other two HTTP versions align with the stats in the Fastly console.

I presume it's an underflow for the value related to the maths at:

fastly-exporter/pkg/realtime/process.go

Line 110 in 2e8b6cf

m.HTTPTotal.WithLabelValues(serviceID, serviceName, datacenter, "1").Add(float64(stats.Requests - (stats.HTTP2 + stats.HTTP3)))
