Synthetics

Client

class Synthetics.Client

A low-level client representing Synthetics

You can use Amazon CloudWatch Synthetics to continually monitor your services. You can create and manage canaries , which are modular, lightweight scripts that monitor your endpoints and APIs from the outside-in. You can set up your canaries to run 24 hours a day, once per minute. The canaries help you check the availability and latency of your web services and troubleshoot anomalies by investigating load time data, screenshots of the UI, logs, and metrics. The canaries seamlessly integrate with CloudWatch ServiceLens to help you trace the causes of impacted nodes in your applications. For more information, see Using ServiceLens to Monitor the Health of Your Applications in the Amazon CloudWatch User Guide .

Before you create and manage canaries, be aware of the security considerations. For more information, see Security Considerations for Synthetics Canaries .

client = session.create_client('synthetics')

These are the available methods:

associate_resource(**kwargs)

Associates a canary with a group. Using groups can help you with managing and automating your canaries, and you can also view aggregated run results and statistics for all canaries in a group.

You must run this operation in the Region where the canary exists.

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
close()

Closes underlying endpoint connections.

create_canary(**kwargs)

Creates a canary. Canaries are scripts that monitor your endpoints and APIs from the outside-in. Canaries help you check the availability and latency of your web services and troubleshoot anomalies by investigating load time data, screenshots of the UI, logs, and metrics. You can set up a canary to run continuously or just once.

Do not use CreateCanary to modify an existing canary. Use UpdateCanary instead.

To create canaries, you must have the CloudWatchSyntheticsFullAccess policy. If you are creating a new IAM role for the canary, you also need the iam:CreateRole , iam:CreatePolicy and iam:AttachRolePolicy permissions. For more information, see Necessary Roles and Permissions .

Do not include secrets or proprietary information in your canary names. The canary name makes up part of the Amazon Resource Name (ARN) for the canary, and the ARN is included in outbound calls over the internet. For more information, see Security Considerations for Synthetics Canaries .

Parameters
  • Name (string) --

    [REQUIRED]

    The name for this canary. Be sure to give it a descriptive name that distinguishes it from other canaries in your account.

    Do not include secrets or proprietary information in your canary names. The canary name makes up part of the canary ARN, and the ARN is included in outbound calls over the internet. For more information, see Security Considerations for Synthetics Canaries .

  • Code (dict) --

    [REQUIRED]

    A structure that includes the entry point from which the canary should start running your script. If the script is stored in an S3 bucket, the bucket name, key, and version are also included.

    • S3Bucket (string) --

      If your canary script is located in S3, specify the bucket name here. Do not include s3:// as the start of the bucket name.

    • S3Key (string) --

      The S3 key of your script. For more information, see Working with Amazon S3 Objects .

    • S3Version (string) --

      The S3 version ID of your script.

    • ZipFile (bytes) --

      If you input your canary script directly into the canary instead of referring to an S3 location, the value of this parameter is the base64-encoded contents of the .zip file that contains the script. It must be smaller than 225 Kb.

      For large canary scripts, we recommend that you use an S3 location instead of inputting it directly with this parameter.

    • Handler (string) -- [REQUIRED]

      The entry point to use for the source code when running the canary. For canaries that use the syn-python-selenium-1.0 runtime or a syn-nodejs.puppeteer runtime earlier than syn-nodejs.puppeteer-3.4 , the handler must be specified as `` fileName .handler`` . For syn-python-selenium-1.1 , syn-nodejs.puppeteer-3.4 , and later runtimes, the handler can be specified as `` fileName .*functionName* `` , or you can specify a folder where canary scripts reside as `` folder /fileName .*functionName* `` .

  • ArtifactS3Location (string) --

    [REQUIRED]

    The location in Amazon S3 where Synthetics stores artifacts from the test runs of this canary. Artifacts include the log file, screenshots, and HAR files. The name of the S3 bucket can't include a period (.).

  • ExecutionRoleArn (string) --

    [REQUIRED]

    The ARN of the IAM role to be used to run the canary. This role must already exist, and must include lambda.amazonaws.com as a principal in the trust policy. The role must also have the following permissions:

    • s3:PutObject
    • s3:GetBucketLocation
    • s3:ListAllMyBuckets
    • cloudwatch:PutMetricData
    • logs:CreateLogGroup
    • logs:CreateLogStream
    • logs:PutLogEvents
  • Schedule (dict) --

    [REQUIRED]

    A structure that contains information about how often the canary is to run and when these test runs are to stop.

    • Expression (string) -- [REQUIRED]

      A rate expression or a cron expression that defines how often the canary is to run.

      For a rate expression, The syntax is rate(*number unit* ) . unit can be minute , minutes , or hour .

      For example, rate(1 minute) runs the canary once a minute, rate(10 minutes) runs it once every 10 minutes, and rate(1 hour) runs it once every hour. You can specify a frequency between rate(1 minute) and rate(1 hour) .

      Specifying rate(0 minute) or rate(0 hour) is a special value that causes the canary to run only once when it is started.

      Use cron(*expression* ) to specify a cron expression. You can't schedule a canary to wait for more than a year before running. For information about the syntax for cron expressions, see Scheduling canary runs using cron .

    • DurationInSeconds (integer) --

      How long, in seconds, for the canary to continue making regular runs according to the schedule in the Expression value. If you specify 0, the canary continues making runs until you stop it. If you omit this field, the default of 0 is used.

  • RunConfig (dict) --

    A structure that contains the configuration for individual canary runs, such as timeout value and environment variables.

    Warning

    The environment variables keys and values are not encrypted. Do not store sensitive information in this field.

    • TimeoutInSeconds (integer) --

      How long the canary is allowed to run before it must stop. You can't set this time to be longer than the frequency of the runs of this canary.

      If you omit this field, the frequency of the canary is used as this value, up to a maximum of 14 minutes.

    • MemoryInMB (integer) --

      The maximum amount of memory available to the canary while it is running, in MB. This value must be a multiple of 64.

    • ActiveTracing (boolean) --

      Specifies whether this canary is to use active X-Ray tracing when it runs. Active tracing enables this canary run to be displayed in the ServiceLens and X-Ray service maps even if the canary does not hit an endpoint that has X-Ray tracing enabled. Using X-Ray tracing incurs charges. For more information, see Canaries and X-Ray tracing .

      You can enable active tracing only for canaries that use version syn-nodejs-2.0 or later for their canary runtime.

    • EnvironmentVariables (dict) --

      Specifies the keys and values to use for any environment variables used in the canary script. Use the following format:

      { "key1" : "value1", "key2" : "value2", ...}

      Keys must start with a letter and be at least two characters. The total size of your environment variables cannot exceed 4 KB. You can't specify any Lambda reserved environment variables as the keys for your environment variables. For more information about reserved keys, see Runtime environment variables .

      Warning

      The environment variables keys and values are not encrypted. Do not store sensitive information in this field.

      • (string) --
        • (string) --

Exceptions

create_group(**kwargs)

Creates a group which you can use to associate canaries with each other, including cross-Region canaries. Using groups can help you with managing and automating your canaries, and you can also view aggregated run results and statistics for all canaries in a group.

Groups are global resources. When you create a group, it is replicated across Amazon Web Services Regions, and you can view it and add canaries to it from any Region. Although the group ARN format reflects the Region name where it was created, a group is not constrained to any Region. This means that you can put canaries from multiple Regions into the same group, and then use that group to view and manage all of those canaries in a single view.

Groups are supported in all Regions except the Regions that are disabled by default. For more information about these Regions, see Enabling a Region .

Each group can contain as many as 10 canaries. You can have as many as 20 groups in your account. Any single canary can be a member of up to 10 groups.

Other resources used and created by the canary are not automatically deleted. After you delete a canary that you do not intend to use again, you should also delete the following:

  • The CloudWatch alarms created for this canary. These alarms have a name of ``Synthetics-SharpDrop-Alarm-MyCanaryName `` .
  • Amazon S3 objects and buckets, such as the canary's artifact location.
  • IAM roles created for the canary. If they were created in the console, these roles have the name ``role/service-role/CloudWatchSyntheticsRole-MyCanaryName `` .
  • CloudWatch Logs log groups created for the canary. These logs groups have the name ``/aws/lambda/cwsyn-MyCanaryName `` .

Before you delete a canary, you might want to use GetCanary to display the information about this canary. Make note of the information returned by this operation so that you can delete these resources after you delete the canary.

describe_canaries(**kwargs)

This operation returns a list of the canaries in your account, along with full details about each canary.

This operation supports resource-level authorization using an IAM policy and the Names parameter. If you specify the Names parameter, the operation is successful only if you have authorization to view all the canaries that you specify in your request. If you do not have permission to view any of the canaries, the request fails with a 403 response.

You are required to use the Names parameter if you are logged on to a user or role that has an IAM policy that restricts which canaries that you are allowed to view. For more information, see Limiting a user to viewing specific canaries .

Parameters
  • NextToken (string) -- A token that indicates that there is more data available. You can use this token in a subsequent operation to retrieve the next set of results.
  • MaxResults (integer) -- Specify this parameter to limit how many canaries are returned each time you use the DescribeCanaries operation. If you omit this parameter, the default of 100 is used.
  • Names (list) --

    Use this parameter to return only canaries that match the names that you specify here. You can specify as many as five canary names.

    If you specify this parameter, the operation is successful only if you have authorization to view all the canaries that you specify in your request. If you do not have permission to view any of the canaries, the request fails with a 403 response.

    You are required to use this parameter if you are logged on to a user or role that has an IAM policy that restricts which canaries that you are allowed to view. For more information, see Limiting a user to viewing specific canaries .

tag_resource(**kwargs)

Assigns one or more tags (key-value pairs) to the specified canary or group.

Tags can help you organize and categorize your resources. You can also use them to scope user permissions, by granting a user permission to access or change only resources with certain tag values.

Tags don't have any semantic meaning to Amazon Web Services and are interpreted strictly as strings of characters.

You can use the TagResource action with a resource that already has tags. If you specify a new tag key for the resource, this tag is appended to the list of tags associated with the resource. If you specify a tag key that is already associated with the resource, the new tag value that you specify replaces the previous value for that tag.

You can associate as many as 50 tags with a canary or group.

Parameters
  • Name (string) --

    [REQUIRED]

    The name of the canary that you want to update. To find the names of your canaries, use DescribeCanaries .

    You cannot change the name of a canary that has already been created.

  • Code (dict) --

    A structure that includes the entry point from which the canary should start running your script. If the script is stored in an S3 bucket, the bucket name, key, and version are also included.

    • S3Bucket (string) --

      If your canary script is located in S3, specify the bucket name here. Do not include s3:// as the start of the bucket name.

    • S3Key (string) --

      The S3 key of your script. For more information, see Working with Amazon S3 Objects .

    • S3Version (string) --

      The S3 version ID of your script.

    • ZipFile (bytes) --

      If you input your canary script directly into the canary instead of referring to an S3 location, the value of this parameter is the base64-encoded contents of the .zip file that contains the script. It must be smaller than 225 Kb.

      For large canary scripts, we recommend that you use an S3 location instead of inputting it directly with this parameter.

    • Handler (string) -- [REQUIRED]

      The entry point to use for the source code when running the canary. For canaries that use the syn-python-selenium-1.0 runtime or a syn-nodejs.puppeteer runtime earlier than syn-nodejs.puppeteer-3.4 , the handler must be specified as `` fileName .handler`` . For syn-python-selenium-1.1 , syn-nodejs.puppeteer-3.4 , and later runtimes, the handler can be specified as `` fileName .*functionName* `` , or you can specify a folder where canary scripts reside as `` folder /fileName .*functionName* `` .

  • ExecutionRoleArn (string) --

    The ARN of the IAM role to be used to run the canary. This role must already exist, and must include lambda.amazonaws.com as a principal in the trust policy. The role must also have the following permissions:

    • s3:PutObject
    • s3:GetBucketLocation
    • s3:ListAllMyBuckets
    • cloudwatch:PutMetricData
    • logs:CreateLogGroup
    • logs:CreateLogStream
    • logs:CreateLogStream
  • RuntimeVersion (string) -- Specifies the runtime version to use for the canary. For a list of valid runtime versions and for more information about runtime versions, see Canary Runtime Versions .
  • Schedule (dict) --

    A structure that contains information about how often the canary is to run, and when these runs are to stop.

    • Expression (string) -- [REQUIRED]

      A rate expression or a cron expression that defines how often the canary is to run.

      For a rate expression, The syntax is rate(*number unit* ) . unit can be minute , minutes , or hour .

      For example, rate(1 minute) runs the canary once a minute, rate(10 minutes) runs it once every 10 minutes, and rate(1 hour) runs it once every hour. You can specify a frequency between rate(1 minute) and rate(1 hour) .

      Specifying rate(0 minute) or rate(0 hour) is a special value that causes the canary to run only once when it is started.

      Use cron(*expression* ) to specify a cron expression. You can't schedule a canary to wait for more than a year before running. For information about the syntax for cron expressions, see Scheduling canary runs using cron .

    • DurationInSeconds (integer) --

      How long, in seconds, for the canary to continue making regular runs according to the schedule in the Expression value. If you specify 0, the canary continues making runs until you stop it. If you omit this field, the default of 0 is used.

  • RunConfig (dict) --

    A structure that contains the timeout value that is used for each individual run of the canary.

    Warning

    The environment variables keys and values are not encrypted. Do not store sensitive information in this field.

    • TimeoutInSeconds (integer) --

      How long the canary is allowed to run before it must stop. You can't set this time to be longer than the frequency of the runs of this canary.

      If you omit this field, the frequency of the canary is used as this value, up to a maximum of 14 minutes.

    • MemoryInMB (integer) --

      The maximum amount of memory available to the canary while it is running, in MB. This value must be a multiple of 64.

    • ActiveTracing (boolean) --

      Specifies whether this canary is to use active X-Ray tracing when it runs. Active tracing enables this canary run to be displayed in the ServiceLens and X-Ray service maps even if the canary does not hit an endpoint that has X-Ray tracing enabled. Using X-Ray tracing incurs charges. For more information, see Canaries and X-Ray tracing .

      You can enable active tracing only for canaries that use version syn-nodejs-2.0 or later for their canary runtime.

    • EnvironmentVariables (dict) --

      Specifies the keys and values to use for any environment variables used in the canary script. Use the following format:

      { "key1" : "value1", "key2" : "value2", ...}

      Keys must start with a letter and be at least two characters. The total size of your environment variables cannot exceed 4 KB. You can't specify any Lambda reserved environment variables as the keys for your environment variables. For more information about reserved keys, see Runtime environment variables .

      Warning

      The environment variables keys and values are not encrypted. Do not store sensitive information in this field.
