The current ganglia reporter doesn't set metric expiration time (dmax). The metrics of all finished applications are indefinitely left displayed in ganglia web. The dmax parameter allows user to set the lifetime of the metrics. The default value is 0 for compatibility with previous versions. Author: Ekasit Kijsipongse <ekasitk@gmail.com> Closes #11127 from ekasitk/ganglia-dmax.

|
|
|
|
# This file configures Spark's internal metrics system. The metrics system is
|
|
# divided into instances which correspond to internal components.
|
|
# Each instance can be configured to report its metrics to one or more sinks.
|
|
# Accepted values for [instance] are "master", "worker", "executor", "driver",
|
|
# and "applications". A wildcard "*" can be used as an instance name, in
|
|
# which case all instances will inherit the supplied property.
|
|
#
|
|
# Within an instance, a "source" specifies a particular set of grouped metrics.
|
|
# there are two kinds of sources:
|
|
# 1. Spark internal sources, like MasterSource, WorkerSource, etc, which will
|
|
# collect a Spark component's internal state. Each instance is paired with a
|
|
# Spark source that is added automatically.
|
|
# 2. Common sources, like JvmSource, which will collect low level state.
|
|
# These can be added through configuration options and are then loaded
|
|
# using reflection.
|
|
#
|
|
# A "sink" specifies where metrics are delivered to. Each instance can be
|
|
# assigned one or more sinks.
|
|
#
|
|
# The sink|source field specifies whether the property relates to a sink or
|
|
# source.
|
|
#
|
|
# The [name] field specifies the name of source or sink.
|
|
#
|
|
# The [options] field is the specific property of this source or sink. The
|
|
# source or sink is responsible for parsing this property.
|
|
#
|
|
# Notes:
|
|
# 1. To add a new sink, set the "class" option to a fully qualified class
|
|
# name (see examples below).
|
|
# 2. Some sinks involve a polling period. The minimum allowed polling period
|
|
# is 1 second.
|
|
# 3. Wildcard properties can be overridden by more specific properties.
|
|
# For example, master.sink.console.period takes precedence over
|
|
# *.sink.console.period.
|
|
# 4. A metrics specific configuration
|
|
# "spark.metrics.conf=${SPARK_HOME}/conf/metrics.properties" should be
|
|
# added to Java properties using -Dspark.metrics.conf=xxx if you want to
|
|
# customize metrics system. You can also put the file in ${SPARK_HOME}/conf
|
|
# and it will be loaded automatically.
|
|
# 5. The MetricsServlet sink is added by default as a sink in the master,
|
|
# worker and driver, and you can send HTTP requests to the "/metrics/json"
|
|
# endpoint to get a snapshot of all the registered metrics in JSON format.
|
|
# For master, requests to the "/metrics/master/json" and
|
|
# "/metrics/applications/json" endpoints can be sent separately to get
|
|
# metrics snapshots of the master instance and applications. This
|
|
# MetricsServlet does not have to be configured.
