SDK for PHP 3.x

Client: Aws\InternetMonitor\InternetMonitorClient
Service ID: internetmonitor
Version: 2021-06-03

This page describes the parameters and results for the operations of the Amazon CloudWatch Internet Monitor (2021-06-03), and shows how to use the Aws\InternetMonitor\InternetMonitorClient object to call the described operations. This documentation is specific to the 2021-06-03 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

Operations

CreateMonitor

$result = $client->createMonitor([/* ... */]);
$promise = $client->createMonitorAsync([/* ... */]);

Creates a monitor in Amazon CloudWatch Internet Monitor. A monitor is built based on information from the application resources that you add: VPCs, Network Load Balancers (NLBs), Amazon CloudFront distributions, and Amazon WorkSpaces directories. Internet Monitor then publishes internet measurements from Amazon Web Services that are specific to the city-networks. That is, the locations and ASNs (typically internet service providers or ISPs), where clients access your application. For more information, see Using Amazon CloudWatch Internet Monitor in the Amazon CloudWatch User Guide.

When you create a monitor, you choose the percentage of traffic that you want to monitor. You can also set a maximum limit for the number of city-networks where client traffic is monitored, that caps the total traffic that Internet Monitor monitors. A city-network maximum is the limit of city-networks, but you only pay for the number of city-networks that are actually monitored. You can update your monitor at any time to change the percentage of traffic to monitor or the city-networks maximum. For more information, see Choosing a city-network maximum value in the Amazon CloudWatch User Guide.

]);

Parameter Details

Members
ClientToken
Type: string

A unique, case-sensitive string of up to 64 ASCII characters that you specify to make an idempotent API request. Don't reuse the same client token for other API requests.

HealthEventsConfig
Type: HealthEventsConfig structure

Defines the threshold percentages and other configuration information for when Amazon CloudWatch Internet Monitor creates a health event. Internet Monitor creates a health event when an internet issue that affects your application end users has a health score percentage that is at or below a specific threshold, and, sometimes, when other criteria are met.

If you don't set a health event threshold, the default value is 95%.

For more information, see Change health event thresholds in the Internet Monitor section of the CloudWatch User Guide.

InternetMeasurementsLogDelivery

Publish internet measurements for Internet Monitor to an Amazon S3 bucket in addition to CloudWatch Logs.

MaxCityNetworksToMonitor
Type: int

The maximum number of city-networks to monitor for your resources. A city-network is the location (city) where clients access your application resources from and the ASN or network provider, such as an internet service provider (ISP), that clients access the resources through. Setting this limit can help control billing costs.

To learn more, see Choosing a city-network maximum value in the Amazon CloudWatch Internet Monitor section of the CloudWatch User Guide.

MonitorName
Required: Yes
Type: string

The name of the monitor.

Resources
Type: Array of strings

The resources to include in a monitor, which you provide as a set of Amazon Resource Names (ARNs). Resources can be VPCs, NLBs, Amazon CloudFront distributions, or Amazon WorkSpaces directories.

You can add a combination of VPCs and CloudFront distributions, or you can add WorkSpaces directories, or you can add NLBs. You can't add NLBs or WorkSpaces directories together with any other resources.

If you add only Amazon VPC resources, at least one VPC must have an Internet Gateway attached to it, to make sure that it has internet connectivity.

Tags
Type: Associative array of custom strings keys (TagKey) to strings

The tags for a monitor. You can add a maximum of 50 tags in Internet Monitor.

TrafficPercentageToMonitor
Type: int

The percentage of the internet-facing traffic for your application that you want to monitor with this monitor. If you set a city-networks maximum, that limit overrides the traffic percentage that you set.

To learn more, see Choosing an application traffic percentage to monitor in the Amazon CloudWatch Internet Monitor section of the CloudWatch User Guide.

AvailabilityMeasurement

Description

Amazon CloudWatch Internet Monitor calculates measurements about the availability for your application's internet traffic between client locations and Amazon Web Services. Amazon Web Services has substantial historical data about internet performance and availability between Amazon Web Services services and different network providers and geographies. By applying statistical analysis to the data, Internet Monitor can detect when the performance and availability for your application has dropped, compared to an estimated baseline that's already calculated. To make it easier to see those drops, we report that information to you in the form of health scores: a performance score and an availability score.

Availability in Internet Monitor represents the estimated percentage of traffic that is not seeing an availability drop. For example, an availability score of 99% for an end user and service location pair is equivalent to 1% of the traffic experiencing an availability drop for that pair.

For more information, see How Internet Monitor calculates performance and availability scores in the Amazon CloudWatch Internet Monitor section of the Amazon CloudWatch User Guide.

Members
ExperienceScore
Type: double

Experience scores, or health scores are calculated for different geographic and network provider combinations (that is, different granularities) and also summed into global scores. If you view performance or availability scores without filtering for any specific geography or service provider, Amazon CloudWatch Internet Monitor provides global health scores.

The Amazon CloudWatch Internet Monitor chapter in the CloudWatch User Guide includes detailed information about how Internet Monitor calculates health scores, including performance and availability scores, and when it creates and resolves health events. For more information, see How Amazon Web Services calculates performance and availability scores in the Amazon CloudWatch Internet Monitor section of the CloudWatch User Guide.

PercentOfClientLocationImpacted
Type: double

The percentage of impact caused by a health event for client location traffic globally.

For information about how Internet Monitor calculates impact, see Inside Internet Monitor in the Amazon CloudWatch Internet Monitor section of the Amazon CloudWatch User Guide.

PercentOfTotalTrafficImpacted
Type: double

The impact on total traffic that a health event has, in increased latency or reduced availability. This is the percentage of how much latency has increased or availability has decreased during the event, compared to what is typical for traffic from this client location to the Amazon Web Services location using this client network.

InternetHealth

Description

Internet health includes measurements calculated by Amazon CloudWatch Internet Monitor about the performance and availability for your application on the internet. Amazon Web Services has substantial historical data about internet performance and availability between Amazon Web Services services and different network providers and geographies. By applying statistical analysis to the data, Internet Monitor can detect when the performance and availability for your application has dropped, compared to an estimated baseline that's already calculated. To make it easier to see those drops, Internet Monitor reports the information to you in the form of health scores: a performance score and an availability score.

Members
Availability
Type: AvailabilityMeasurement structure

Availability in Internet Monitor represents the estimated percentage of traffic that is not seeing an availability drop. For example, an availability score of 99% for an end user and service location pair is equivalent to 1% of the traffic experiencing an availability drop for that pair.

For more information, see How Internet Monitor calculates performance and availability scores in the Amazon CloudWatch Internet Monitor section of the CloudWatch User Guide.

Performance
Type: PerformanceMeasurement structure

Performance in Internet Monitor represents the estimated percentage of traffic that is not seeing a performance drop. For example, a performance score of 99% for an end user and service location pair is equivalent to 1% of the traffic experiencing a performance drop for that pair.

PerformanceMeasurement

Description

Amazon CloudWatch Internet Monitor calculates measurements about the performance for your application's internet traffic between client locations and Amazon Web Services. Amazon Web Services has substantial historical data about internet performance and availability between Amazon Web Services services and different network providers and geographies. By applying statistical analysis to the data, Internet Monitor can detect when the performance and availability for your application has dropped, compared to an estimated baseline that's already calculated. To make it easier to see those drops, we report that information to you in the form of health scores: a performance score and an availability score.

Performance in Internet Monitor represents the estimated percentage of traffic that is not seeing a performance drop. For example, a performance score of 99% for an end user and service location pair is equivalent to 1% of the traffic experiencing a performance drop for that pair.

For more information, see How Internet Monitor calculates performance and availability scores in the Amazon CloudWatch Internet Monitor section of the CloudWatch User Guide.
