Amazon ECS Input Plugin

Amazon ECS, Fargate compatible, input plugin which uses the Amazon ECS metadata and stats v2 or [v3][task-metadata-endpoint-v3] API endpoints to gather stats on running containers in a Task.

The telegraf container must be run in the same Task as the workload it is inspecting.

This is similar to (and reuses a few pieces of) the Docker input plugin, with some ECS specific modifications for AWS metadata and stats formats.

The amazon-ecs-agent (though it is a container running on the host) is not present in the metadata/stats endpoints.

}

Ecs config object

func (*Ecs) Description 

func (ecs *Ecs) Description() string

Description describes ECS plugin

func (*Ecs) Gather 

func (ecs *Ecs) Gather(acc telegraf.Accumulator) error

Gather is the entrypoint for telegraf metrics collection

func (*Ecs) SampleConfig 

func (ecs *Ecs) SampleConfig() string

SampleConfig returns the ECS example config

type EcsClient 

type EcsClient struct {
	// contains filtered or unexported fields
}

EcsClient contains ECS connection config

func NewClient 

func NewClient(timeout time.Duration, endpoint string, version int) (*EcsClient, error)

NewClient constructs an ECS client with the passed configuration params

func (*EcsClient) ContainerStats 

func (c *EcsClient) ContainerStats() (map[string]types.StatsJSON, error)

ContainerStats calls the ECS stats endpoint and returns a populated container stats map

func (*EcsClient) Task 

func (c *EcsClient) Task() (*Task, error)

Task calls the ECS metadata endpoint and returns a populated Task

type Network 

type Network struct {
	NetworkMode   string
	IPv4Addresses []string
}

Network is a docker network configuration

type Task 

type Task struct {
