Access payload data values (not just log count as timeseries)

1

(Grafana Cloud and GCP Stackdriver)

  1. Create a metric using SD as data source
  2. Select ‘Logging’ and then an existing Metric
  3. Change the visualization to a table
    Result: You see 2 columns: the timestamp and a hit count

Question: Can I also return a value(s) or a portion of the log itself? Preferable with a targeted key from the Payload. (e.x.: jsonPayload.data.initial_request.foo)
