TDengine datasource plugin

[sangshuduo]

TDengine is an open-source big data platform designed and optimized for Internet of Things (IoT), Connected Vehicles, and Industrial IoT. Besides the 10x faster time-series database, it provides caching, stream computing, message queuing and other functionalities to reduce the complexity and costs of development and operations.

For verifying the TDengine data source plugin, please refer to https://www.taosdata.com/en/documentation/connections-with-other-tools/#Grafana. But need change TDengine RESTful port from 6020 to 6041.

TDengine docker can be run as following command:

docker run tdengine/tdengine:latest
Thanks.

Hi @sangshuduo,

Could you please package the plugin as a ZIP archive and validate it (paste the URL to a ZIP archive containing the plugin)?

[sangshuduo]

@marcusolsson

I tried to input 'https://github.com/taosdata/grafanaplugin/releases/download/v2.0.0/taosdata-tdengine-datasource.zip' on 'validate it' service but got 'Internal Server Error'. Since the it can validate other zip file. I guess something wrong in my zip file led its dysfunction but no clue how to solve my package now. Could you please help to try? Thanks.

@daniellee @marcusolsson could you please kindly help to see what's the detail of the internal server error? I have no any clue what's wrong and how to fix it. thanks!

You can run the validator locally as well (more information here):

$ plugincheck https://github.com/taosdata/grafanaplugin/releases/download/v2.0.0/taosdata-tdengine-datasource.zip
unexpected status code: 409

I'm getting a 409 Conflict error, but I'm not quite sure why. I'll try to troubleshoot this and get back to you.

@marcusolsson thanks.

@sangshuduo the plugin.json has some typo:

"keywords": "timeseries", "time-series", "database", "IoT", 
    "monitoring", "datasource", "taosdata", "tdengine",

==>

"keywords": ["timeseries", "time-series", "database", "IoT", 
   "monitoring", "datasource", "taosdata", "tdengine"],

so make plugincheck wierd behavior.

@marcusolsson Here: https://github.com/grafana/plugin-validator/blob/master/pkg/plugin/check.go#L213 no error check, so the ID is empty, later when check org the 409 found.

@nanjj  thanks for your comment. I will upload new one soon.

[marcusolsson]

@nanjj Good catch! As an FYI, we're working on version 2 of the plugin validator which will have more checks, as well as be more configurable. You can try it out here: https://github.com/grafana/plugin-validator/tree/master/cmd/plugincheck2

[nanjj]

@sangshuduo so where is the new one?

[sangshuduo]

@nanjj thanks for asking. we are working on the plugin refactoring. will submit to official repository later after development complete.
