Metrics

[dominickp]

It would be useful if Whoogle output metrics, or if there was a way to export them somehow. I think it would be interesting to track when an instance is rate limited. I'd like to setup Prometheus alerts on this. I'd like to prevent setting up an external system like uptime-kuma or similar from doing an actual search. Between the farside rate limiting checks and the random bots querying directly for health, just querying internally on whether or not rate limiting is happening seems like it wouldn't make the problem any worse.
