How to access spark executor, worker and master level metrics in databricks?

My question is specific to databricks. I am trying to access spark metrics via graphite sink in databricks by passing below spark configuration and I want the configuration to be passed while creating a cluster.

spark.metrics.conf.*.sink.graphite.class org.apache.spark.metrics.sink.GraphiteSink
spark.metrics.conf.*.sink.graphite.host myhost
spark.metrics.conf.*.sink.graphite.port 2003
spark.metrics.conf.*.sink.graphite.period 10
spark.metrics.conf.*.sink.graphite.unit seconds
spark.metrics.conf.*.source.jvm.class org.apache.spark.metrics.source.JvmSource

However, the above configuration only fetches driver level metrics. I read in some posts that to get executor level metrics, one has to pass below parameters

spark-submit <other parameters> --files metrics.properties 
--conf spark.metrics.conf=metrics.properties

My question is how can I pass --files parameter in databricks while creating a cluster (as I am not doing spark-submit) or is there any other way to get executor, worker and master level metrics ?

The --jars, --py-files, --files arguments support DBFS paths.

You can specify as shown below in the spark submit with the path to the metrics file.

--files=dbfs/yourPath/metrics.properties --conf spark.metrics.conf=./metrics.properties

Reference: Azure Databricks Jobs API - SparkSubmitTask

This article gives an example of how to monitor Apache Spark components using the Spark configurable metrics system. Specifically, it shows how to set a new source and enable a sink.
