Michał Łowicki Nice article, though I have one doubt

enabled = True
host = localhost
port = 8778
path = cassandra.jmx
mbeans = '''
org.apache.cassandra.metrics:type=Compaction,name=BytesCompacted |
org.apache.cassandra.metrics:type=Compaction,name=CompletedTasks |
org.apache.cassandra.metrics:type=Compaction,name=PendingTasks
'''

is this need to go into diamond.conf file?
