CPU activity, disk usage, temperatures, RAM—nothing escapes your monitoring. Beszel also lets you configure notifications and alerts when your predefined thresholds are exceeded. Beszel includes a hub with a web UI and an agent that collects data from your server or a remote server. ![Beszel](/img/serveex/beszel.png) ## Installation --- Folder structure ```console root └── docker └── beszel ├── data └── socket ``` Open Dockge, click `compose`, name the stack `beszel`, and paste the following: ```yaml --- services: beszel: image: henrygd/beszel:latest container_name: beszel restart: unless-stopped ports: - ${PORT}:8090 volumes: - ./data:/beszel_data - ./socket:/beszel_socket beszel-agent: image: henrygd/beszel-agent:latest container_name: beszel-agent restart: unless-stopped network_mode: host volumes: - ./socket:/beszel_socket - /var/run/docker.sock:/var/run/docker.sock:ro environment: LISTEN: /beszel_socket/beszel.sock # Do not remove quotes around the key KEY: ${KEY} ``` ::alert{type="success"} ✨ __Tip:__ Add the Watchtower label to each container to automate updates. ```yaml services: beszel: #... labels: - com.centurylinklabs.watchtower.enable=true ``` :: Fill out the `.env` file, for example: ```properties PORT=8090 # web UI port KEY= # private key to retrieve from Beszel when adding a system ``` For the `KEY` value, you'll need to launch Beszel once to get it. Deploy the container and go to `http://yourserverip:8090`. Your Beszel web UI is now accessible! ::alert{type="danger"} :::list{type="danger"} - __If it fails:__ check your firewall rules. ::: :: ### Add local server information Now that the web UI is accessible, you need to push local server information into it. Just add a machine via the web UI and configure it like this: ![Beszel add system](/img/serveex/beszel-add.png) Note the private key and confirm. Enter the key in your `.env` file in Dockge and redeploy the stack. Once done, your server will appear in the web UI: ![Beszel system](/img/serveex/beszel-system.png) ### Add a remote server You can also monitor a remote server. To do so, run the agent on the remote server. Add a new machine in Beszel and fill in: - The name displayed for your remote server - The IP address or domain name of the remote server - The listening port (e.g., `45876`) Beszel will suggest a `compose.yaml` to deploy on the remote server, or you can use: ```yaml --- services: beszel-agent: image: henrygd/beszel-agent container_name: beszel-agent restart: unless-stopped network_mode: host volumes: - /var/run/docker.sock:/var/run/docker.sock:ro environment: LISTEN: ${PORT} KEY: ${KEY} ``` And in `.env`: ```properties PORT=45876 # communication port between hub and remote agent KEY= # private key from Beszel when adding the system ``` Deploy the stack on the remote server. Data will begin flowing into the web UI after a few seconds. ::alert{type="danger"} :::list{type="danger"} - __If it fails:__ check your firewall rules. ::: :: ## Expose Beszel with Swag --- ::alert{type="warning"} :::list{type="warning"} - Beszel does not support multi-factor authentication. Exposing it on the internet could compromise connected machines. Only do this if you're using a system like [Authentik](/serveex/security/authentik/). Otherwise, do not expose with SWAG—use a VPN like [Wireguard](/serveex/security/wireguard) instead. ::: :: If you want to access Beszel remotely from all your devices, expose it using Swag. ::alert{type="info"} 📋 __Prerequisite:__

You must have created a DNS subdomain like `beszel.mydomain.com` with a `CNAME` pointing to `mydomain.com`, and—unless you're using Cloudflare Zero Trust—you must have forwarded port `443` on your router to your server’s `443` port via [NAT rules](/general/networking/nat). :: In Dockge, edit Swag's compose file and add Beszel’s network: ```yaml services: swag: container_name: # ... # ... networks: # ... - beszel # network declared in the stack networks: # ... beszel: name: beszel_default # actual external network name external: true ``` Redeploy the stack and wait for Swag to become fully operational. ::alert{type="info"} :::list{type="info"} - We assume the network name is `beszel_default`. You can check connectivity by visiting Swag's dashboard at `http://yourserverip:81`. ::: :: In Swag’s config folders, create `beszel.subdomain.conf`. ::alert{type="success"} ✨ __Tip:__ Use [File Browser](/serveex/files/file-browser) to browse and edit files instead of terminal commands. :: ```shell sudo vi /docker/swag/config/nginx/proxy-confs/beszel.subdomain.conf ``` Press `i` to enter insert mode and paste: ```nginx ## Version 2023/12/19 server { listen 443 ssl; listen [::]:443 ssl; server_name beszel.*; include /config/nginx/ssl.conf; client_max_body_size 0; #if ($lan-ip = yes) { set $geo-whitelist yes; } #if ($geo-whitelist = no) { return 404; } if ($geo-blacklist = no) { return 404; } # enable for ldap auth #include /config/nginx/ldap-server.conf; # enable for Authelia #include /config/nginx/authelia-server.conf; # enable for Authentik #include /config/nginx/authentik-server.conf; location / { #auth_basic "Restricted"; #auth_basic_user_file /config/nginx/.htpasswd; #include /config/nginx/ldap-location.conf; #include /config/nginx/authelia-location.conf; #include /config/nginx/authentik-location.conf; include /config/nginx/proxy.conf; include /config/nginx/resolver.conf; set $upstream_app beszel; set $upstream_port 8090; set $upstream_proto http; proxy_pass $upstream_proto://$upstream_app:$upstream_port; } } ``` Press `Esc`, type `:x`, and hit `Enter` to save and exit. That’s it—Beszel is now exposed! ::alert{type="success"} ✨ You can protect this app with Authentik by opening `beszel.subdomain.conf` and removing the `#` in front of `include /config/nginx/authentik-server.conf;` and `include /config/nginx/authentik-location.conf;`. Don’t forget to [create an application and provider in Authentik](/serveex/security/authentik#protecting-an-app-via-reverse-proxy). ::
