Sum values from jsonpath

[Zabbix_Julian]

Hello all,

I created an item with an HTTP agent.
I now want to monitor a Json file.
Here there are the following 2 entries: "ErrorCount & NewCount", the item should now sum both values from the json.


So: ErrorCount 16 + NewCount 217 = 233

Does anyone have an idea how I can do this in preprocessing?


Thanks in advance.

$.['ErrorCount','NewCount'].sum()
