Amazon EMR monitoring integration

New Relic infrastructure integrations include an integration for reporting your Amazon EMR (Elastic MapReduce) data to New Relic. This document explains how to activate this integration and describes the data that can be reported.

Features

You can monitor and alert on your EMR data directly from New Relic, and query data and create dashboards.

Activate integration

To enable this integration follow standard procedures to Connect AWS services to New Relic.

Configuration and polling

You can change the polling frequency and filter data using configuration options.

Default polling information for the Amazon EMR integration:

  • New Relic polling interval: 5 minutes
  • Resolution: 1 data point every 5 minutes

Explore integration data

To use your integration data, go to one.newrelic.com > Infrastructure > AWS and select one of the EMR integration links.

You can query and explore your data using the ElasticMapReduceClusterSample event type, with a provider value of ElasticMapReduceCluster.

Metric data

This New Relic Infrastructure integration collects the following Amazon EMR data. For use cases and additional information, see Amazon's EMR documentation.

Name

Description

isIdle

Indicates that a cluster is no longer performing work, but is still alive and accruing charges. It is set to 1 if no tasks are running and no jobs are running, and set to 0 otherwise.

This value is checked at five-minute intervals, and a value of 1 indicates only that the cluster was idle when checked, not that it was idle for the entire five minutes. Recommendation: To avoid false positives, raise an alerting threshold when this value has been 1 for more than one consecutive five-minute check. For example, raise an alert on this value if it has been 1 for thirty minutes or longer.

coreNodesRunning

The number of core nodes working. Data points for this metric are reported only when a corresponding instance group exists.

coreNodesPending

The number of core nodes waiting to be assigned. All of the core nodes requested may not be immediately available; this metric reports the pending requests. Data points for this metric are reported only when a corresponding instance group exists.

liveDataNodesPercentage

The percentage of data nodes that are receiving work from Hadoop.

s3WrittenBytes

The number of bytes written to Amazon S3. This metric aggregates MapReduce jobs only. It does not apply for other workloads on EMR.

s3ReadBytes

The number of bytes read from Amazon S3. This metric aggregates MapReduce jobs only, and does not apply for other workloads on EMR.

hdfsUtilizationPercentage

The percentage of HDFS storage currently used.

hdfsReadBytes

The number of bytes read from HDFS.

hdfsWrittenBytes

The number of bytes written to HDFS.

missingBlocks

The number of blocks in which HDFS has no replicas. These might be corrupt blocks.

totalLoad

The current, total number of readers and writers reported by all DataNodes in a cluster.

mostRecentBackupDurationMinutes

The amount of time it took the previous backup to complete. This metric is set regardless of whether the last completed backup succeeded or failed.

While the backup is ongoing, this metric returns the number of minutes after the backup started. This metric is only reported for HBase clusters.

timeSinceLastSuccessfulBackupMinutes

The number of elapsed minutes after the last successful HBase backup started on your cluster. This metric is only reported for HBase clusters.

The following metrics appear in the sample depending on the Hadoop version of the resource.

Hadoop 1 AMIs metrics

Name

Description

jobsRunning

The number of jobs in the cluster that are currently running.

jobsFailed

The number of jobs in the cluster that have failed.

mapTasksRunning

The number of running map tasks for each job. If you have a scheduler installed and multiple jobs running, multiple graphs are generated.

mapTasksRemaining

The number of remaining map tasks for each job. If you have a scheduler installed and multiple jobs running, multiple graphs are generated. A remaining map task is one that is not in any of the following states: Running, Killed, or Completed.

mapSlotsOpen

The unused map task capacity. This is calculated as the maximum number of map tasks for a given cluster, less the total number of map tasks currently running in that cluster.

remainingMapTasksPerSlot

The ratio of the total map tasks remaining to the total map slots available in the cluster.

reduceTasksRunning

The number of running reduce tasks for each job. If you have a scheduler installed and multiple jobs running, multiple graphs are generated.

reduceTasksRemaining

The number of running reduce tasks for each job. If you have a scheduler installed and multiple jobs running, multiple graphs are generated.

reduceSlotsOpen

Unused reduce task capacity. This is calculated as the maximum reduce task capacity for a given cluster, less the number of reduce tasks currently running in that cluster.

taskNodesRunning

The number of task nodes working. Data points for this metric are reported only when a corresponding instance group exists.

taskNodesPending

The number of core nodes waiting to be assigned. All of the task nodes requested may not be immediately available; this metric reports the pending requests. Data points for this metric are reported only when a corresponding instance group exists.

liveTaskTrackersPercentage

The percentage of task trackers that are functional.

backupFailed

Whether the last backup failed. This is set to 0 by default and updated to 1 if the previous backup attempt failed. This metric is only reported for HBase clusters.

Hadoop 2 AMIs metrics

Name

Description

containerAllocated

The number of resource containers allocated by the ResourceManager.

containerReserved

The number of resource containers allocated by the ResourceManager.

containerPending

The number of containers in the queue that have not yet been allocated.

containerPendingRatio

The ratio of pending containers to containers allocated.

appsCompleted

The number of applications submitted to YARN that have completed.

appsFailed

The number of applications submitted to YARN that have failed to complete.

appsKilled

The number of applications submitted to YARN that have been killed.

appsPending

The number of applications submitted to YARN that are in a pending state.

appsRunning

The number of applications submitted to YARN that are running.

appsSubmitted

The number of applications submitted to YARN.

mrTotalNodes

The number of nodes presently available to MapReduce jobs.

mrActiveNodes

The number of nodes presently running MapReduce tasks or jobs.

mrLostNodes

The number of nodes allocated to MapReduce that have been marked in a LOST state.

mrUnhealthyNodes

The number of nodes available to MapReduce jobs marked in an UNHEALTHY state.

mrDecommissionedNodes

The number of nodes allocated to MapReduce applications that have been marked in a DECOMMISSIONED state.

mrRebootedNodes

The number of nodes available to MapReduce that have been rebooted and marked in a REBOOTED state.

corruptBlocks

The number of blocks that HDFS reports as corrupted.

memoryTotalBytes

The total amount of memory in the cluster.

memoryReservedBytes

The amount of memory reserved.

memoryAvailableBytes

The amount of memory available to be allocated.

capacityRemainingBytes

The amount of remaining HDFS disk capacity.

hbaseBackupFailed

Whether the last backup failed. This is set to 0 by default and updated to 1 if the previous backup attempt failed. This metric is only reported for HBase clusters.

Inventory data

Inventory data provides information about the service's state and configuration. EMR configuration options are reported as inventory data.

ヒント

Cluster data indicated with an * and all instance, instance-fleet, and instance-group metadata are only fetched if extended inventory collection is on.
