Grafana Image Renderer with IOT Dashboard V2.6

[tszalkai]

Hi,

I downloaded and installed the Grafana image renderer grafana-image-renderer-3.11.1.linux-amd64.zip to the IOT Dashboard Plugins App Folder. I changed the grafana.ini file as follows:

[plugin.grafana-image-renderer]
;rendering_timezone = America/New_York
;rendering_language = en
;rendering_viewport_device_scale_factor = 2
;rendering_ignore_https_errors = true
;rendering_verbose_logging =
;rendering_dumpio =
;rendering_args =
;rendering_chrome_bin =
;rendering_mode = clustered
;rendering_clustering_mode = browser
;rendering_clustering_max_concurrency = 5
;rendering_clustering_timeout = 30
;rendering_viewport_max_width = 1000
;rendering_viewport_max_height = 500
;rendering_viewport_max_device_scale_factor = 4
;grpc_host =
;grpc_port =

. As I click on a panels' share, I can see the image rendering option, see below.

Unfortunately, after clicking the link, it errors out with Page Not Found, see below.

Is grafana Image Renderer not supported within the IOT Dashboard app?

Hi @tszalkai ,

Could you please explain more of your process here? First of all, where did you get the plugin zip file?

The way I read the documentation implies there is a Chromium browser packaged with the plugin that depends on additional shared libraries. It's possible these are not included with the ctrlX OS distribution. You can check over SSH.

cd <grafana-image-render plugin directory>
ldd chrome-linux/chrome
      linux-vdso.so.1 (0x00007fff1bf65000)
      libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f2047945000)
      libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f2047924000)
      librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f204791a000)
      libX11.so.6 => not found
      libX11-xcb.so.1 => not found
      libxcb.so.1 => not found
      libXcomposite.so.1 => not found
        ...

 In general, this plugin sounds better suited to run on a device that is both hosting and viewing the Grafana web server.

@tszalkai ,

I set this up locally and confirmed that a number of the libraries required for Chrome are missing in ctrlX OS. Unfortunately, this plugin will not function.
