Service Metrics

MapR services produce metrics that can be written to an output file or consumed by Ganglia. The file metrics output is directed by the hadoop-metrics.properties files.

By default, the CLDB and FileServer metrics are sent via unicast to the Ganglia gmon server running on localhost. To send the metrics directly to a Gmeta server, change the cldb.servers property to the hostname of the Gmeta server. To send the metrics to a multicast channel, change the cldb.servers property to the IP address of the multicast channel.

The following sections provide information about the metrics collected and how to manage service metrics:
