I have recently started using the Azure monitor plugin for application Insights (and it’s awesome!) however a key feature for me is being able to group by a field within a JSON object. Hard to explain so let me give an example…
Within Application Insights under my performance counters table there’s a ‘customDimensions’ column where the values are JSON objects. Within this JSON object, one value is ‘Docker Host’. Within Grafana I create a graph and edit it’s metrics to look for the performance counters table and select ‘processor CPU percentage’. This all works, I now want to ‘Group By’ my ‘Docker Host’ value. I can select ‘customDimensions/Docker host’ from the drop down but only to receive an error. In the top right of my graph a red explanation mark shows, the error within has no details under ‘Panel Description’ and this as the response:
“message”: “Unexpected error occurred”,
Is this a known bug or am I doing something wrong? Any help is appreciated.
Thank you for your time,
