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 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:
