aws ec2 metricset

edit

The ec2 metricset of aws module allows you to monitor your AWS EC2 instances, including cpu, network, disk and status. ec2 metricset fetches a set of values from Cloudwatch AWS EC2 Metrics.

We fetch the following data:

  • cpu.total.pct: The percentage of allocated EC2 compute units that are currently in use on the instance.
  • cpu.credit_usage: The number of CPU credits spent by the instance for CPU utilization.
  • cpu.credit_balance: The number of earned CPU credits that an instance has accrued since it was launched or started.
  • cpu.surplus_credit_balance: The number of surplus credits that have been spent by an unlimited instance when its CPUCreditBalance value is zero.
  • cpu.surplus_credits_charged: The number of spent surplus credits that are not paid down by earned CPU credits, and which thus incur an additional charge.
  • network.in.packets: The number of packets received on all network interfaces by the instance.
  • network.out.packets: The number of packets sent out on all network interfaces by the instance.
  • network.in.bytes: The number of bytes received on all network interfaces by the instance.
  • network.out.bytes: The number of bytes sent out on all network interfaces by the instance.
  • diskio.read.bytes: Bytes read from all instance store volumes available to the instance.
  • diskio.write.bytes: Bytes written to all instance store volumes available to the instance.
  • diskio.read.ops: Completed read operations from all instance store volumes available to the instance in a specified period of time.
  • diskio.write.ops: Completed write operations to all instance store volumes available to the instance in a specified period of time.
  • status.check_failed: Reports whether the instance has passed both the instance status check and the system status check in the last minute.
  • status.check_failed_system: Reports whether the instance has passed the system status check in the last minute.
  • status.check_failed_instance: Reports whether the instance has passed the instance status check in the last minute.
  • instance.core.count: The number of CPU cores for the instance.
  • instance.image.id: The ID of the image used to launch the instance.
  • instance.monitoring.state: Indicates whether detailed monitoring is enabled.
  • instance.private.dns_name: The private DNS name of the network interface.
  • instance.private.ip: The private IPv4 address associated with the network interface.
  • instance.public.dns_name: The public DNS name of the instance.
  • instance.public.ip: The address of the Elastic IP address (IPv4) bound to the network interface.
  • instance.state.code: The state of the instance, as a 16-bit unsigned integer.
  • instance.threads_per_core: The state of the instance (pending | running | shutting-down | terminated | stopping | stopped).

AWS Permissions

edit

Some specific AWS permissions are required for IAM user to collect AWS EC2 metrics.

ec2:DescribeInstances

Dashboard

edit

The aws ec2 metricset comes with a predefined dashboard. For example:
