Elastic Compute Cloud (EC2)

Overview

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud.

Setup

Installation

If you haven't already, first set up the AWS CloudWatch integration. No additional steps are needed for installation.

Configuration

On the AWS CloudWatch integration page, ensure that the EC2 service is selected for metric collection.

Metrics

AppOptics supports the ability to filter by tag for EC2 resources. For more information, please see our instructions on filtering metrics using tags.

Name Description

CPUCreditUsage

(count)

For T2 Instances. The number of CPU credits consumed by the instance. One CPU credit equals one vCPU running at 100% utilization for one minute or an equivalent combination of vCPUs, utilization, and time (for example, one vCPU running at 50% utilization for two minutes or two vCPUs running at 25% utilization for two minutes).

CPUCreditBalance

(count)

For T2 Instances. The 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.

CPUUtilization

(percent)

The percentage 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.

DiskReadOps

(count)

Completed read operations from all instance store volumes available to the instance in a specified period of time.

DiskWriteOps

(count)

Completed write operations to all instance store volumes available to the instance in a specified period of time.

DiskReadBytes

(bytes)

Bytes read from all instance store volumes available to the instance. This metric is used to determine the volume of the data the application reads from the hard disk of the instance. This can be used to determine the speed of the application.

DiskWriteBytes

(bytes)

Bytes written to all instance store volumes available to the instance. This metric is used to determine the volume of the data the application writes onto the hard disk of the instance. This can be used to determine the speed of the application.

NetworkIn

(bytes)

The number of bytes received on all network interfaces by the instance. This metric identifies the volume of incoming network traffic to a single instance.

NetworkOut

(bytes)

The number of bytes sent out on all network interfaces by the instance. This metric identifies the volume of outgoing network traffic from a single instance.

NetworkPacketsIn

(count)

The number of packets received on all network interfaces by the instance. This metric identifies the volume of incoming traffic in terms of the number of packets on a single instance. This metric is available for basic monitoring only.

NetworkPacketsOut

(count)

The number of packets sent out on all network interfaces by the instance. This metric identifies the volume of outgoing traffic in terms of the number of packets on a single instance. This metric is available for basic monitoring only.

StatusCheckFailed

(count)

Reports whether the instance has passed both the instance status check and the system status check in the last minute.

This metric can be either 0 (passed) or 1 (failed).

StatusCheckFailed_Instance

(count)

Reports whether the instance has passed the instance status check in the last minute.

This metric can be either 0 (passed) or 1 (failed).

StatusCheckFailed_System

(count)

Reports whether the instance has passed the system status check in the last minute.

This metric can be either 0 (passed) or 1 (failed).
