Need suggestions on how to create dashboard by using splunk data

I am trying to create grafana dashboard by using data which is there in Splunk.

I added splunk datasource, do I need to query in SPL language (splunk search processing language to get data) to fetch data which is available in Splunk (particularly Control-M job’s log data)
