EC2 Auto Scaling Group Monitoring Integration

Amazon EC2 Auto Scaling enables you to scale the instances according to the varying demands of the application workload. Auto Scaling group is a logical collection of EC2 instances arranged together for scaling. With Site24x7, you can monitor resource utilization metrics like CPU usage at the group level and alert on them to make informed decisions about configuring scaling policies.

Manage EC2 auto scaling groups

Setup and configuration

1. If you haven't done so already, enable access to your AWS resources between your AWS account and Site24x7's AWS account by either:

  • Creating Site24x7 as an IAM user
  • Creating a cross-account IAM role. Learn more

2. On the Integrate AWS Account page, check the box next to EC2 Auto Scaling. Learn more

Policies and permissions

The following permissions are required by Site24x7 to discover EC2 Auto Scaling groups and collect configuration information. Learn more

  • "autoscaling:DescribeAccountLimits",
  • "autoscaling:DescribeScheduledActions",
  • "autoscaling:DescribeLaunchConfigurations",
  • "autoscaling:DescribeNotificationConfigurations",
  • "autoscaling:DescribeScalingActivities",
  • "autoscaling:DescribeAutoScalingGroups",
  • "autoscaling:DescribeLifecycleHooks",
  • "application-autoscaling:DescribeScalableTargets"

Polling Frequency

Site24x7 queries AWS to collect EC2 Auto Scaling performance metrics according to the configured poll frequency. The minimum poll interval supported is one minute, and the maximum is 24 hours. Learn more

Supported metrics

1. Resource Metrics

AttributeDescriptionStatisticData Type
CPU utilization Measures the percentage of allocated CPU units that are in use by the instance Average Percentage
Disk read operations Measures the number of read operations completed on all your instance store volumes Sum Count
Disk write operations Measures the number of write operations completed on all your instance store volumes Sum Count
Disk read bytes Measures the bytes read from all your instance store volumes Sum MB
Disk write bytes Bytes written to all instance store volumes Sum MB
Network in Measures the number of bytes received on all network interfaces Sum MB
Network out Measures the number of bytes sent out on all network interfaces Sum MB
Network packets in Measures the number of packets received on all network interfaces Sum Count
Network packets out Measures the number of packets sent out on all network interfaces Sum Count
Status Check Failed Reports if the instance has failed both the instance status check and the system status check Maximum Count
Status Check Failed Instance Reports if the instance has failed the instance status check Maximum Count
Status Check Failed System Reports if the instance has failed the system status check Maximum Count

2. EC2 Auto Scaling Group Metrics

AttributeDescriptionStatisticData Type
Group Minimum Size The minimum size of the Auto Scaling group Minimum Count
Group Maximum Size The maximum size of the Auto Scaling group Maximum Count
Desired Capacity The number of instances that the Auto Scaling group attempts to maintain Maximum Count
In-Service Instances The number of instances that are running as part of the Auto Scaling group Maximum Count
Pending Instances The number of instances that are pending. A pending instance is not yet in service Maximum Count
StandBy Instances The number of instances that are in a Standby state. Instances in this state are still running but are not actively in service Maximum Count
Terminating Instances The number of instances that are in the process of terminating Maximum Count
Total Instances The total number of instances in the Auto Scaling group Maximum Count

Summary

Gain an overview of different processes occurring within each group with time series charts that provide the events timeline on outages, CPU utilization, network traffic, network packets activity, disk I/O operation activity. disk I/O byte activity, and status checks on a group.

Configuration

The configuration details of a group are provided under this tab. The details you may find here are desired capacity, group maximum size, group minimum size, availability zones, health check type, health check grace period, instance protection, termination policies, service-linked role, etc.

EC2 Instances

The metadata information of the EC2 instances under this particular group are displayed under this tab.

Activity History

The activity history of the scaling operations performed within a group is described within this tab.

Scaling Policies

The scaling policies with information on policy name, policy type, and their corresponding details are provided.

Notifications

The type of scaling action performed and its corresponding notification gets displayed under this tab.

Scheduled Actions

The upcoming scaling actions configured by the user, are displayed under this tab. The details provided are action name, start time, the maximum size of the group and the minimum size of the group.

Lifecycle Hooks

Auto Scaling lifecycle hooks enable you to perform custom actions like Auto Scaling launches or that which terminates instances. The tab provides you with information such as name, heartbeat timeout (sec), timeout (sec), default result and lifecycle transition.
