Usage in general (new to grafane etc)

[alturismo]

May as a starter for me to get some sample usage here, i setted up a REST serving GPU data in json formatting which i would like to bring to my grafana dash

respond as sample from http://192.168.1.210:55555

[ { "SensorApp": "GPU-Z", "SensorClass": "GPU", "SensorName": "GPU Clock", "SensorValue": "300", "SensorUnit": "MHz", "SensorUpdateTime": 264958 }, { "SensorApp": "GPU-Z", "SensorClass": "GPU", "SensorName": "Memory Clock", "SensorValue": "101,25", "SensorUnit": "MHz", "SensorUpdateTime": 264958 }, { "SensorApp": "GPU-Z", "SensorClass": "GPU", "SensorName": "GPU Temperature", "SensorValue": "34", "SensorUnit": "°C", "SensorUpdateTime": 264958 }, ... { "SensorApp": "GPU-Z", "SensorClass": "GPU", "SensorName": "PerfCap Reason", "SensorValue": "1", "SensorUnit": "", "SensorUpdateTime": 264958 }, { "SensorApp": "GPU-Z", "SensorClass": "GPU", "SensorName": "GPU Voltage", "SensorValue": "0,725", "SensorUnit": "V", "SensorUpdateTime": 264958 } ]

now, i added the datasource standard via url

now comes the interesting part, i guess its not plug and play so i have to add queries

may a startpoint how to use it to get the values properly readed ?

for any Tipps, thanks ahead

ok, 1 step further ;)

now i take a look how to make them as graphs with timeline, any hints, thanks ahead ;)

Looking good!

Each visualisation in Grafana requires queries with specific sets of field types. For example, the Graph panel can graph any query that return a Time and a Number field.

thanks, i d need to know how to sep. fetch then individual terms from the json i assume, would be nice for a sample like "CPU Clock" in case u have the time.

[marcusolsson]

What do you mean by "individual terms"? The JSON Path can return single values, and not just arrays?

[alturismo]

im sure they do, i just dont know how (yet) ;)

[marcusolsson]

Would something like this work for you?

JSON data:

{
  "host": "instance-1",
  "cpu": 0.45
}

thanks for trying to help, i spent some time now but actually with no result to get a scaled graph.

i stay simple now with the table i have ;)

goal was more as sample some graphical showoffs

thanks again for pointing, but somehow i dont understand the query's and how to use them properly, nevermind now ;)
