Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed elastic NFS file system for use with AWS Cloud services and on-premise resources.
Amazon EFS is built to scale on demand to petabytes without disrupting applications. Amazon EFS:
- Grows and shrinks automatically as files are added and removed.
- Eliminates the need to provision.
- Manages capacity to accommodate growth.
Amazon EFS has the following features:
- A simple web services interface that allows you to create and configure file systems quickly and easily. The service manages all of the file storage infrastructure to avoid the complexity of deploying, patching, and maintaining complex file system configurations.
- Support for the Network File System version 4 (NFSv4.1 and NFSv4.0) protocol so your applications and tools work seamlessly with Amazon EFS.
- Support for multiple Amazon EC2 instances that can access an Amazon EFS file system (at the same time), providing a common data source for workloads and applications running on more than one instance or server.
Use the AWS public cloud integration to discover and collect metrics against the AWS service.

Supported metrics
| OpsRamp Metric | AWS Metric | Metric Display Name | Unit | Aggregation Type | Description |
|---|---|---|---|---|---|
| aws_efs_TimeSinceLastSync | TimeSinceLastSync | Time Since Last Sync | Seconds | Average | Shows the amount of time that has passed since the last successful sync to the destination file system in a replication configuration. |
| aws_efs_PercentIOLimit | PercentIOLimit | Percent IO Limit | Percent | Average | Shows how close a file system is to reaching the I/O limit of the General Purpose performance mode. |
| aws_efs_BurstCreditBalance | BurstCreditBalance | Burst Credit Balance | Bytes | Average | The number of burst credits that a file system has. Burst credits allow a file system to burst to throughput levels above a file system’s baseline level for periods of time. |
| aws_efs_PermittedThroughput | PermittedThroughput | Permitted Throughput | Bytes/Second | Average | The maximum amount of throughput that a file system can drive. |
| aws_efs_MeteredIOBytes | MeteredIOBytes | Metered IO Bytes | Bytes | Average | The number of metered bytes for each file system operation, including data read, data write, and metadata operations, with read operations discounted according to the throughput limit. |
| aws_efs_TotalIOBytes | TotalIOBytes | Total IO Bytes | Bytes | Average | The actual number of bytes for each file system operation processed by Amazon EFS, without any read discounts. |
| aws_efs_DataReadIOBytes | DataReadIOBytes | Data Read IO Bytes | Bytes | Average | The actual number of bytes for each file system read operation. |
| aws_efs_DataWriteIOBytes | DataWriteIOBytes | Data Write IO Bytes | Bytes | Average | The actual number of bytes for each file system write operation. |
| aws_efs_MetadataIOBytes | MetadataIOBytes | Metadata IO Bytes | Bytes | Average | The actual number of bytes for each metadata operation. |
| aws_efs_MetadataReadIOBytes | MetadataReadIOBytes | Metadata Read IO Bytes | Bytes | Average | The actual number of bytes for each metadata read operation. |
| aws_efs_MetadataWriteIOBytes | MetadataWriteIOBytes | Metadata Write IO Bytes | Bytes | Average | The actual number of bytes for each metadata write operation. |
| aws_efs_ClientConnections | ClientConnections | Client Connections | Count | Sum | The number of client connections to a file system. When using a standard client, there is one connection per mounted Amazon EC2 instance. |
| aws_efs_StorageBytes | StorageBytes | Storage Bytes | Bytes | Average | The size of the file system in bytes, including the amount of data stored in the EFS storage classes. |
