I'm trying to access a nested json object when using the string codec format but the key I'm trying to access has a "." in it. What is the correct syntax to do so?
An example of the json is:
{
"json": {
"time": "2019-03-26T18:09:43.396624023Z",
"vars.reference": "alpine",
"http.request.uri": "/v2/admin/glbtest1/manifests/alpine"
}
}
The example string format syntax is:
string: '%{[@timestamp]} %{[message]}'
