Issue with query_manager_metrics in client.rb, returns empty always

[dandu1008]

Am trying the below code to pull AWS EMR Presto query manager metrics, but its always return empty.

require 'presto/metrics'
require 'pp'
client = Presto::Metrics::Client.new(:host => 'localhost', :port=>8889)

client.query_manager_metrics(["abandoned_queries.total_count", "canceled_queries.total_count", "completed_queries.total_count", "execution_time.five_minutes.avg", "failed_queries.total_count", "queued_queries", "queued_time.five_minutes.avg", "running_queries"]).values

client.query_manager_metrics(["executor.active_count", "executor.completed_task_count"])

Presto SQL:

Able to query the metrics by using JXM schema and JXM metric tables in presto sql.
select "completedqueries.totalcount" from jmx.current."com.facebook.presto.execution:name=querymanager";
result: 106

And as per README.md, have tried other metrics like od level, gc metrics, they are working as expected except "query_manager_metrics".

Please look into this issue, and share if you have any fix or quick workaround.

presto-metrics 0.3.12 works with EMR to pull Presto query_manager_metrics.
In higher versions, JMX tables are updated from com.facebook.presto.* to presto.*, which are not exist under jmx schema in presto.
