+# Metrics + instance data + log
+
+(K5NPHQHP)
+
+## ptth_server metrics
+
+These are just like Prometheus. Either counters, or gauges, scalar or histograms.
+
+- CPU usage counter
+- RAM usage gauge
+- Requests received counter
+- Responses sent counter
+- Tokio gauges?
+- Outbound byte counter
+- Uptime gauge
+- Last seen UTC time
+- Free disk space gauge
+
+## ptth_server instance data
+
+These are captured during process start and then don't change. They're kinda
+like metrics, but static.
+
+- Machine ID
+- Git version (if possible)
+- Server ID
+- Random instance ID
+- UTC time at startup
+
+## ptth_server logs
+
+Basically what the tracing crate puts out. See if we can route that over the
+network?
+
+- Metrics, captured every 5 minutes or whatever
+- Probably "warn" level logs from `tracing`

 even with Caddy running a static file server, so I can't prove that it's on my
 side. The VPS is cheap, and the datacenter is far away.

 The bad_passwords file is huge. Since it's static, it should only be in physical
 RAM when the server first launches, and then the kernel will let it be paged
