+
+When you self-host, there comes a moment when curiosity takes over.
+Who visits my site? At what time? Which pages actually get attention?
+
+And, sooner or later, the big question:
+Is anyone, anywhere, really reading what I write?
+
+You could go for Google Analytics or Matomo — but that comes with its own baggage:
+- Questionable privacy practices,
+- Third-party scripts injected into your site,
+- Extra weight on every page,
+- And a dependency on services I don’t want.
+
+GoAccess, on the other hand, takes the minimalist route.
+No scripts, no tracking, no cookie banner — it reads directly from the web server logs (in my case, Caddy) and generates a clear, efficient report.
+
+That’s the kind of philosophy I like:
+- Privacy-friendly — nothing leaves my server, no profiling.
+- Simple — I don’t touch my site, I just process the logs.
+- Fast — one command and I instantly see who visited and how.
+- Self-hosting friendly — no database, no bloated setup.
+
+In short, GoAccess fits perfectly with what I look for in my homelab:
+
+→ Getting visibility into my services without turning it into a Rube Goldberg machine.
+
+⸻
+
+Minimal setup on NixOS
+
+GoAccess is available directly from the official repository.
+I just added the package and a small systemd service to generate a static report every hour:
+
+```
+{pkgs, ...}: {
+  environment.systemPackages = with pkgs; [
+    goaccess
+  ];
+
+  # Service for generation the GoAccess static report
+  systemd.services.goaccess-report = {
+    description = "Generate GoAccess HTML report";
+    serviceConfig = {
+      ExecStart = "${pkgs.goaccess}/bin/goaccess /var/log/caddy/access-levr.porzh.me.log --log-format=CADDY -o /var/www/goaccess/index.html";
+    };
+  };
+
+  # Timer to regénérate the report every hour
+  systemd.timers.goaccess-report = {
+    description = "Hourly GoAccess report generation";
+    wantedBy = ["timers.target"];
+    timerConfig = {
+      OnCalendar = "hourly";
+      Persistent = true;
+    };
+  };
+  services.caddy = {
+    virtualHosts = {
+      "koum.porzh.me" = {
+        extraConfig = ''
+          root * /var/www/goaccess
+          file_server browse
+          try_files {path} {path}/ /index.html
+
+        '';
+      };
+    };
+  };
+}
+```
+
+What’s next?
+
+In the second part, I’ll go a bit further:
+- filtering out local network IPs,
+- generating daily, weekly, and monthly reports,
+- and explaining why I chose not to use the “live” mode.
+
+Because yes — even analytics deserve a bit of restraint.
