logfilegen supports the metrics output in Prometheus/OpenMetrics format.
To request current metrics, just do the HTTP GET request to localhost:8080/metrics
To open the self-hosted logfilegen page with metrics, go to localhost:8080
To redefine default port use --port=number
logfilegen option.
To set the self-hosting page auto-update interval use --poll=seconds
option (default: 15, in seconds)
Please note that per-second metrics are average values, calculated by the division of total value and seconds pass.
