Adding a panel: diagram doesn't appear in list

[jshook]

For both grafana 3.1.1 and latest (4..), I can install the diagram plugin, see it in the plugins screen, but then not see it available in a dashboard when I "add a panel"

This is via docker images for both version, using the following method for testing the plugin addition:

docker exec -i -t grafana /usr/sbin/grafana-cli plugins install jdbranham-diagram-panel
docker restart grafana

[coussej]

Maybe something to do with browser cache? I had the same when installing the plugin, even after restarting grafana, but a hard refresh in chrome did the trick.

[jshook]

perhaps, but that would still be a cache management bug, most likely. I'll verify whether or not that fixes it.

[ksugana]

set it up on REL-7 we have the same problem.

[jdbranham]

do you see the "settings > panels > jdbranham-diagram-panel" in the object [you can use the javascript console in the browser window] -

window.grafanaBootData

[asifmohammedgithub]

Hi Jdbranham

I have the same issue and no i don't see "settings > panels > jdbranham-diagram-panel" in the object window.grafanaBootData

[jdbranham]

@asifmohammedgithub
Are you also using the docker image?

Do you see anything in the logs about loading the plugin, and do you see the plugin folder in "/var/lib/grafana/plugins" [or wherever your plugins are located?]

[ksugana]

Plugin folder is created. I do not see anything in the logs. even enabling debug does not log anything.

[ksugana]

in settings i do not see any panel.

[jdbranham]

using the CLI tool, do you see the plugin installed?

http://docs.grafana.org/plugins/installation/

grafana-cli plugins ls

[ksugana]

yes it does show it .
grafana-cli plugins ls
[sudo] password for ksugana:
installed plugins:
jdbranham-diagram-panel @ 1.3.0

Restart grafana after installing plugins .

[jdbranham]

Are you using a web front end like Apache or Nginx?
Also, have you tried logging out and in of Grafana?

[asifmohammedgithub]

Hi Guys
I got it to work it turned out to be a browser caching issue. When i use firefox private tab i can see the jdbranham plugin.

This seems to be an issue i don't even see new data source I add without clearing my cache or using a private tab. Please investigate, Thanks

[asifmohammedgithub]

Ok, finally got it to work. There are two thing you could try actually.

1. The browser caching issue i mentioned above - Try this first
2. It may be a browser caching issue so try opening grafana in a private tab
   There was a permissions error for plugin in /var/log.grafana.log. So after chown -R grafana:grafana on the plugin directory.

[jshook]

Were the cache controls fixed for this?

[ksugana]

Nope did not work for me, I gave up on it for now.thanks for the reply

@jdbranham Can we keep this open until we can get an upstream fix or something on the radar? It is an actual issue.

[jdbranham]

@jshook
Have you installed any other plugins in this Grafana instance?
If so, do they appear in the list?

[rohit-gandhe]

I have the same problem. I installed using brew. Grafana seems to show plugins dir as /usr/local/Cellar/grafana/4.1.1/share/grafana/data/plugins according to grafana startup logs but when I install plugins using grafana-cli, they are installed in /usr/local/var/lib/grafana/plugins. Even when I copy the plugins from one to another, it doesn't show.

grafana-cli plugins ls shows all the plugins but can't see them on the UI.

[rohit-gandhe]

Actually, after moving the plugin from /usr/local/var/lib/grafana/plugins to /usr/local/Cellar/grafana/4.1.1/share/grafana/data/plugins it does show up in the list.

[rahuldivgan]

Had the same issue, looks like browser cache again. When opened in an incognito mode, it worked.

[praganeshpatel]

I have same issue, try all the option listed above. Still panel not show in GUI -list as well not show in plugin list inside GUI. It shows in command line.

installed plugins:
jdbranham-diagram-panel @ 1.4.3

Restart grafana after installing plugins .

/var/lib/grafana/plugins # service grafana-server restart

Stopping Grafana Server: ... [ OK ]
Starting Grafana Server: ... [ OK ]

/var/lib/grafana/plugins # grafana-cli plugins ls

installed plugins:
jdbranham-diagram-panel @ 1.4.3

I tried different browser including chrome Incognito/firefox-private mode,
change permission on plugin folder from root to grafana
removed/reinstall plugin nothing works and FYI i am using grafana version 4.6.0
I am running it on rhel7 vm.

[jbflowers]

Yup similar issue here. Permissions are set to "grafana:grafana" for the plugins directory in "/var/lib/grafana/plugins". The grafana-cli ls command is showing the diagram plugin installed, however Grafana admin and panels do not show it. Using an influxDB datasource with no other plugins installed. Also tried in a private browsing window with no success.

[humbertowanderley]

Same issue here. all plugins are installed but only the grafana-diagram don't appears on UI. I can see it installed on grafana CLI... tested in diferents browsers, with clean cache, but it is'nt appearing... grafana version 4.6, I'm running it in a docker container with the official image.

[jdbranham]

Do you see anything in the logs regarding the plugin?

[tmagma]

Hi, I have the same problem, this is listed on the grafana.log:

t=2017-11-27T10:40:56-0300 lvl=eror msg="Plugins: Failed to load plugin json file: /var/lib/grafana/plugins/jdbranham-diagram-panel/dist/plugin.json, err: json: cannot unmarshal string into Go struct field PluginInfo.author of type plugins.PluginInfoLink"

grafana-cli plugins ls
installed plugins:
alexanderzobnin-zabbix-app @ 3.7.0
jdbranham-diagram-panel @ 1.4.3
vonage-status-panel @ 1.0.6

Any idea?

thank you

[joeltstephen]

issue is resolved in my system. In your grafana.ini under the path section specify the path of your grafan-diagram plugin. Below is the screenshot for your reference

//Regards
Joel T Stephen

[jdbranham]

To summarize -

Be sure to clear your cache .
Check the log for any plugin initialization issues.
Upgrade to the latest version.
Confirm the grafana.ini has the correct path to the plugin directory.

This would be good information to have in a wiki or on a main site. #18

[jbflowers]

OK was getting this error in the Grafana logs:

t=2017-12-11T14:35:34-0500 lvl=info msg="Starting plugin search" logger=plugins
t=2017-12-11T14:35:34-0500 lvl=eror msg="Plugins: Failed to load plugin json file: /var/lib/grafana/plugins/jdbranham-diagram-panel/dist/plugin.json, err: json: cannot unmarshal string into Go struct field PluginInfo.author of type plugins.PluginInfoLink"

Deleted the existing plugin and reinstalled most up to date as per jdbranham's advice above. Looks like the plugin is loading now!

[jdbranham]

Looks like the only plugin that was detected and load was "Grouped Bar Chart".
per your logs -
_t=2019-08-07T00:16:14+0800 lvl=info msg="Registering plugin" logger=plugins name="Grouped Bar Chart"_

Is the diagram plugin located on your computere here?
D:\Grafana\grafana\data\plugins\jdbranham-diagram-panel

Also, this log shows your server never successfully started, due to a port conflict. Was that a separate issue? It's possible you have two instances of Grafana running. Maybe a long running Grafana instance was never restarted after the diagram plugin was added.

[akfaew]

Uncommenting plugins = /var/lib/grafana/plugins in /etc/grafana/grafana.ini fixed it for me.
