+# Beszel agent
+
+[Beszel](https://github.com/henrygd/beszel) is the monitoring dashboard used
+in this LAN. The hub runs as a Docker container on `docker.sweet.home` (port
+`vars.ports.beszelHub`, 8090). Each monitored NixOS host runs a
+`beszel-agent` that connects back to the hub.
+
+---
+
+## How it works
+
+Everything is handled by a single module:
+
+**`modules/beszel/enable-agent.nix`** — imported by a build type. It:
+- Enables `beszel-agent`
+- Sets `HUB_URL` to `docker.sweet.home:8090`
+- Sets `KEY` from `vars.beszelHubKey` (`variables.nix`) — the hub's SSH
+  public key, shared by every agent. Update `beszelHubKey` if the docker
+  host is ever rebuilt and the hub generates a new keypair.
+- Reads the universal `beszel-token` from `secrets/common.yaml` via sops
+  and passes it to the agent as `TOKEN` in an env file
+- Fixes an upstream bug where the agent couldn't persist its hub-pairing
+  fingerprint across restarts (adds a real `StateDirectory`)
+
+A host file needs no beszel configuration at all — just import the module
+in the build type and add the system in the hub UI.
+
+---
+
+## Adding beszel to a new build type
+
+Add `../beszel/enable-agent.nix` to the `imports` list in
+`modules/build-types/<type>.nix`:
+
+```nix
+imports = [
+  ../beszel/enable-agent.nix
+  # ... other imports
+];
+```
+
+That's the only change required. The host file needs nothing.
+
+---
+
+## Adding a new system to the hub
+
+1. Rebuild and deploy the host with its build type importing `enable-agent.nix`.
+2. Open the beszel hub (`http://docker.sweet.home:8090`).
+3. Go to **Systems → Add system**, enter the host's IP and the default port
+   (45876). The agent will connect and the system will appear as active.
+
+---
+
+## One-time setup: add the token to `secrets/common.yaml`
+
+The universal token is stored once in the common secrets file, shared by all
+agents. Only needed once, not per-host:
+
+```sh
+sops secrets/common.yaml
+```
+
+Add:
+```yaml
+beszel-token: <token from the beszel hub Settings → Keys>
+```
+
+`secrets/common.yaml` is already a sops recipient for every host via their
+SSH host keys, so no additional sops recipient setup is needed.
+
+---
+
+## Optional: monitoring extra filesystems
+
+To report disk usage for a mount beyond the root filesystem, add
+`EXTRA_FILESYSTEMS` in the host file:
+
+```nix
+services.beszel.agent.environment = {
+  EXTRA_FILESYSTEMS = "/mnt/data";   # colon-separated for multiple paths
+};
+```
+
+The `server` host uses this to expose its ZFS data pool:
+
+```nix
+services.beszel.agent.environment = {
+  EXTRA_FILESYSTEMS = "${vars.storageRoot}/${vars.nfsShares.dockerVolumes.subpath}";
+  LOG_LEVEL = "debug";
+};
+```
+
+---
+
+## Optional: monitoring Docker containers
+
+`enable-agent.nix` has a commented-out line for Docker monitoring:
+
+```nix
+#DOCKER_HOST = "tcp://docker-socket-proxy:2375";
+```
+
+Uncomment it if the host runs docker-socket-proxy and you want per-container
+stats. Hosts without Docker should leave it commented out.
+
+---
+
+## If the hub key changes
+
+If the docker host is ever rebuilt and beszel generates a new SSH keypair,
+update `beszelHubKey` in `variables.nix` and rebuild all beszel-enabled hosts.
+The new key is visible in the beszel hub under **Settings → Keys**.
