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:
