Grafana Kiosk

A very useful feature of Grafana is the ability to display dashboards and playlists on a large TV.

This provides a utility to quickly standup a kiosk on devices like a Raspberry Pi or NUC.

The utitilty provides these options:

Login
- to a Grafana server (local account)
- to a Grafana server with anonymous-mode enabled (same method used on play.grafana.org)
- to a Grafana Cloud instance
- to a Grafana server with OAuth enabled
Switch to kiosk or kiosk-tv mode
Display the default home page set for the user
Display a specified dashboard
Start a playlist immediately (inactive mode enable)
Can specify where to start kiosk for multiple displays

Additionally, an initialize option is provided to configure LXDE for Raspberry Pi Desktop.

Hosted Grafana using grafana.com authentication

This will login to a Hosted Grafana instance and take the browser to the default dashboard in fullscreen kiosk mode:

./bin/grafana-kiosk -URL=https://bkgann3.grafana.net -login-method=gcom -username=bkgann -password=abc123 -kiosk-mode=full

This will login to a Hosted Grafana instance and take the browser to a specific dashboard in tv kiosk mode:

./bin/grafana-kiosk -URL=https://bkgann3.grafana.net/dashboard/db/sensu-summary -login-method=gcom -username=bkgann -password=abc123 -kiosk-mode tv

This will login to a Hosted Grafana instance and take the browser to a playlist in fullscreen kiosk mode, and autofit the panels to fill the display.

./bin/grafana-kiosk -URL=https://bkgann3.grafana.net/playlists/play/1 -login-method=gcom -username=bkgann -password=abc123 -kiosk-mode=full -playlists -autofit=true

Grafana Server with Local Accounts

This will login to a grafana server that uses local accounts:

./bin/grafana-kiosk -URL=https://localhost:3000 -login-method=local -username=admin -password=admin -kiosk-mode=tv

If you are using a self-signed certificate, you can remove the certificate error with -ignore-certificate-errors

./bin/grafana-kiosk -URL=https://localhost:3000 -login-method=local -username=admin -password=admin -kiosk-mode=tv -ignore-certificate-errors

Grafana Server with Anonymous access enabled

This will take the browser to the default dashboard on play.grafana.org in fullscreen kiosk mode (no login needed):

./bin/grafana-kiosk -URL=https://play.grafana.org -login-method=anon -kiosk-mode=tv

This will take the browser to a playlist on play.grafana.org in fullscreen kiosk mode (no login needed):

./bin/grafana-kiosk -URL=https://play.grafana.org/playlists/play/1 -login-method=anon -kiosk-mode=tv

Grafana Server with Api Key

This will take the browser to the default dashboard on play.grafana.org in fullscreen kiosk mode:

./bin/grafana-kiosk -URL=https://play.grafana.org -login-method apikey --apikey "xxxxxxxxxxxxxxx" -kiosk-mode=tv

Grafana Server with Generic Oauth

This will login to a Generic Oauth service, configured on Grafana. Oauth_auto_login is disabeld. As Oauth provider is Keycloak used.

go run pkg/cmd/grafana-kiosk/main.go -URL=https://my.grafana.oauth/playlists/play/1  -login-method=goauth -username=test -password=test

This will login to a Generic Oauth service, configured on Grafana. Oauth_auto_login is disabeld. As Oauth provider is Keycloak used and also the login and password html input name is set.

go run pkg/cmd/grafana-kiosk/main.go -URL=https://my.grafana.oauth/playlists/play/1 -login-method=goauth -username=test -password=test -field-username=username -field-password=password

This will login to a Generic Oauth service, configured on Grafana. Oauth_auto_login is enabled. As Oauth provider is Keycloak used and also the login and password html input name is set.

go run pkg/cmd/grafana-kiosk/main.go -URL=https://my.grafana.oauth/playlists/play/1 -login-method=goauth -username=test -password=test -field-username=username -field-password=password -auto-login=true

Google Idtoken authentication

This allows you to log in through Google Identity Aware Proxy using a service account through injecting authorization headers with bearer tokens into each request. the idtoken library will generate new tokens as needed on expiry, allowing grafana kiosk mode without exposing a fully privileged google user on your kiosk device.

./bin/grafana-kiosk -URL=https://play.grafana.org/playlists/play/1 -login-method=idtoken -keyfile /tmp/foo.json -audience myoauthid.apps.googleusercontent.com

LXDE Options

The -lxde option initializes settings for the desktop.

Actions Performed:

sets profile via lxpanel to LXDE
sets pcmanfs profile to LXDE
runs xset s off to disable screensaver
runs xset -dpms to disable power-saving (prevents screen from turning off)
runs xset s noblank disables blank mode for screensaver (maybe not needed)
runs unclutter to hide the mouse

The -lxde-home option allows you to specify a different $HOME directory where the lxde configuration files can be found.

Automatic Startup

Session-based

LXDE can start the kiosk automatically by creating this file:

Create/edit the file: /home/pi/.config/lxsession/LXDE-pi/autostart

/usr/bin/grafana-kiosk -URL=https://bkgann3.grafana.net/dashboard/db/sensu-summary -login-method=gcom -username=bkgann -password=abc123 -kiosk-mode=full -lxde

Session with disconnected "screen"

Alternatively you can run grafana-kiosk under screen, which can very useful for debugging.

Create/edit the file: /home/pi/.config/lxsession/LXDE-pi/autostart

screen -d -m bash -c "/usr/bin/grafana-kiosk -URL=https://bkgann3.grafana.net/dashboard/db/sensu-summary -login-method=gcom -username=bkgann -password=abc123 -kiosk-mode=full -lxde"

Desktop Link

Create/edit the file: /home/pi/.config/autostart/grafana-kiosk.desktop

Troubleshooting

Timeout Launching

2020/08/24 10:18:41 Launching local login kiosk
panic: websocket url timeout reached

Often this is due to lack of entropy, for linux you would need to install rng-tools (or an equivalent).

apt install rng-tools

Building

A Makefile is provided for building the utility.

make

This will generate executables in "bin" that can be run on a variety of platforms.

TODO

RHEL/CentOS auto-startup
Everything in issues!
