Introduction

Amazon Relational Database Service (Amazon RDS) is a web service that makes it easier to set up, operate, and scale a relational database in the AWS Cloud. It provides cost-efficient, resizable capacity for an industry-standard relational database and manages common database administration tasks.

DB instances

A DB instance is an isolated database environment in the AWS Cloud with the following characteristics:

  • An DB instance can contain multiple user-created databases.
  • An DB instance runs a DB engine. Amazon RDS currently supports the MySQL, MariaDB, PostgreSQL, Oracle, and Microsoft SQL Server DB engines.
  • Each DB engine has its own supported features and each version of a DB engine may include specific features.
  • Each DB engine has a set of parameters in a DB parameter group that control the behavior of the databases that it manages.

You can do the following:

  • Access a DB instance by using the same tools and applications that are used with a standalone database instance.
  • Create and modify a DB instance by using the AWS Command Line Interface, the Amazon RDS API, or the AWS Management Console.

Setup

To set up the OpsRamp AWS integration and discover the AWS service, go to AWS Integration Discovery Profile and select RDS.

Metrics

OpsRamp MetricMetric Display NameUnitAggregation TypeDescription
cloud.instance.stateStatus/Staten/an/an/a
aws_rds_CPUUtilizationCPU utilizationPercentMAXPercentage of allocated EC2 compute units that are currently in use on the instance. This metric identifies the processing power required to run an application upon a selected instance.
aws_rds_BinLogDiskUsageBinLogDiskUsageBytesAVERAGEAmount of disk space occupied by binary logs on the master. Applies to MySQL read replicas.
aws_rds_DatabaseConnectionsDatabaseConnectionsCountAVERAGENumber of database connections in use.
aws_rds_DiskQueueDepthDiskQueueDepthCountAVERAGENumber of outstanding IOs (read/write requests) waiting to access the disk.
aws_rds_FreeableMemoryFreeableMemoryFreeable MemoryAVERAGEAmount of available random access memory.
aws_rds_FreeStorageSpaceFreeStorageSpaceFree SpaceAVERAGEAmount of available storage space.
aws_rds_SwapUsageSwapUsageSwap UsageAVERAGEAmount of swap space used on the DB Instance.
aws_rds_NetworkReceiveThroughputNetworkReceiveThroughputAVERAGEIncoming (receive) network traffic on the DB instance, including both customer database traffic and Amazon RDS traffic used for monitoring and replication.
aws_rds_NetworkTransmitThroughputNetworkTransmitThroughputAVERAGEOutgoing (transmit) network traffic on the DB instance, including both customer database traffic and Amazon RDS traffic used for monitoring and replication.
aws_rds_ReadThroughputReadThroughputAVERAGEAverage number of bytes read from disk per second.
aws_rds_WriteThroughputWriteThroughputAVERAGEAverage number of bytes written to disk per second.
aws_rds_ReadIOPSReadIOPSCount/SecAVERAGEAverage number of disk read operations per second
aws_rds_WriteIOPSWriteIOPSCount/SecAVERAGEAverage number of write operations per second.
aws_rds_ReadLatencyReadLatencySecsAVERAGEAverage amount of time taken for disk read I/O operations.
aws_rds_WriteLatencyWriteLatencySecsAVERAGEAverage amount of time taken for disk write I/O operations.
aws_rds_ReplicaLagReplicaLagSecsAVERAGEAmount of time a Read Replica DB Instance lags behind the source DB Instance. Applies to MySQL read replicas.
aws_rds_CPUCreditBalanceCPUCreditBalanceCountAVERAGE[T2 instances] Number of CPU credits available for the instance to burst beyond its base CPU utilization. Credits are stored in the credit balance after they are earned and removed from the credit balance after they expire. Credits expire 24 hours after they are earned. CPU credit metrics are available only at a 5 minute frequency.
aws_rds_CPUCreditUsageCPUCreditUsageCountAVERAGE[T2 instances] Number of CPU credits available for the instance to burst beyond its base CPU utilization. Credits are stored in the credit balance after they are earned and removed from the credit balance after they expire. Credits expire 24 hours after they are earned. CPU credit metrics are available only at a 5 minute frequency.
aws_rds_BurstBalanceBurstBalancePercentAverageUsed with General Purpose SSD (gp2), Throughput Optimized HDD (st1), and Cold HDD (sc1) volumes only. Provides information about Percentage of I/O credits (for gp2) or throughput credits (for st1 and sc1) remaining in the burst bucket. Data is reported to CloudWatch only when the volume is active. If the volume is not attached, no data is reported.
