Redis command from Google Cloud Monitoring DS

Hi, I’m using this datasource: Google Cloud Monitoring data source | Grafana documentation

Trying to check how many keys are in a queue, but this is not an available metric.
Checking redis commands, there is this command that returns what I’m expecting: LLEN

Is it possible to run redis commands from a panel with Google Cloud Monitoring datasource?
Or through MQL or any other way?

Best regards
