improvement of stats

[x70b1]

endlessh is a wonderful tool.

At the moment there are loglines like:
2020-02-03T13:30:38.268Z TOTALS connects=359 seconds=10691.941 bytes=12632

A clean stats interface would be better. Cutting the data out of the logs is not very smooth. Especially in a docker environment.

Additionally stats about a "CURRENT" state would be helpful too, like current connected clients.

A more ingest-friendly stat format or interface would definitely be helpful! Maybe output to json for events and more comprehensive statistics. Or interacting with a socket.

"CURRENT" state

This is in each ACCEPT log line as n=[# of current connections]/[max # of connections]

Also it is still possible to extract some good info from the log! Without using the stat signal this is what I came up with using loki + docker driver + grafana:

Read the source code. If you send a SIGUSR1 to the application, it dumps the statistics to log.

You are also welcome to try my Grafana dashboard (simpler with my go implementation):
