describe-fleet-history

Description

Describes the events for the specified EC2 Fleet during the specified time.

EC2 Fleet events are delayed by up to 30 seconds before they can be described. This ensures that you can query by the last evaluated time and not miss a recorded event. EC2 Fleet events are available for 48 hours.

For more information, see Monitor fleet events using Amazon EventBridge in the Amazon EC2 User Guide .

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  describe-fleet-history
[--dry-run | --no-dry-run]
[--event-type <value>]
[--max-results <value>]
[--next-token <value>]
--fleet-id <value>
--start-time <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--event-type (string)

The type of events to describe. By default, all events are described.

Possible values:

  • instance-change
  • fleet-change
  • service-error

--max-results (integer)

The maximum number of results to return in a single call. Specify a value between 1 and 1000. The default value is 1000. To retrieve the remaining results, make another call with the returned NextToken value.

--next-token (string)

The token for the next set of results.

--fleet-id (string)

The ID of the EC2 Fleet.

--start-time (timestamp)

The start date and time for the events, in UTC format (for example, YYYY -MM -DD T*HH* :MM :SS Z).

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

To describe EC2 Fleet history

The following describe-fleet-history example returns the history for the specified EC2 Fleet starting at the specified time. The output is for an EC2 Fleet with two running instances.

aws ec2 describe-fleet-history \
    --fleet-ids fleet-12a34b55-67cd-8ef9-ba9b-9208dEXAMPLE \
    --start-time 2020-09-01T00:00:00Z

Output

HistoryRecords -> (list)

Information about the events in the history of the EC2 Fleet.

(structure)

Describes an event in the history of an EC2 Fleet.

EventInformation -> (structure)

Information about the event.

EventDescription -> (string)

The description of the event.

EventSubType -> (string)

The event.

error events:
  • iamFleetRoleInvalid - The EC2 Fleet or Spot Fleet does not have the required permissions either to launch or terminate an instance.
  • allLaunchSpecsTemporarilyBlacklisted - None of the configurations are valid, and several attempts to launch instances have failed. For more information, see the description of the event.
  • spotInstanceCountLimitExceeded - You've reached the limit on the number of Spot Instances that you can launch.
  • spotFleetRequestConfigurationInvalid - The configuration is not valid. For more information, see the description of the event.
fleetRequestChange events:
  • active - The EC2 Fleet or Spot Fleet request has been validated and Amazon EC2 is attempting to maintain the target number of running instances.
  • cancelled - The EC2 Fleet or Spot Fleet request is canceled and has no running instances. The EC2 Fleet or Spot Fleet will be deleted two days after its instances are terminated.
  • cancelled_running - The EC2 Fleet or Spot Fleet request is canceled and does not launch additional instances. Its existing instances continue to run until they are interrupted or terminated. The request remains in this state until all instances are interrupted or terminated.
  • cancelled_terminating - The EC2 Fleet or Spot Fleet request is canceled and its instances are terminating. The request remains in this state until all instances are terminated.
  • expired - The EC2 Fleet or Spot Fleet request has expired. If the request was created with TerminateInstancesWithExpiration set, a subsequent terminated event indicates that the instances are terminated.
  • modify_in_progress - The EC2 Fleet or Spot Fleet request is being modified. The request remains in this state until the modification is fully processed.
  • modify_succeeded - The EC2 Fleet or Spot Fleet request was modified.
  • submitted - The EC2 Fleet or Spot Fleet request is being evaluated and Amazon EC2 is preparing to launch the target number of instances.
  • progress - The EC2 Fleet or Spot Fleet request is in the process of being fulfilled.
instanceChange events:
  • launched - A new instance was launched.
  • terminated - An instance was terminated by the user.
  • termination_notified - An instance termination notification was sent when a Spot Instance was terminated by Amazon EC2 during scale-down, when the target capacity of the fleet was modified down, for example, from a target capacity of 4 to a target capacity of 3.
Information events:
  • fleetProgressHalted - The price in every launch specification is not valid because it is below the Spot price (all the launch specifications have produced launchSpecUnusable events). A launch specification might become valid if the Spot price changes.
  • launchSpecTemporarilyBlacklisted - The configuration is not valid and several attempts to launch instances have failed. For more information, see the description of the event.
  • launchSpecUnusable - The price in a launch specification is not valid because it is below the Spot price.
  • registerWithLoadBalancersFailed - An attempt to register instances with load balancers failed. For more information, see the description of the event.
