Monitor Amazon Location Service with Amazon CloudWatch

Amazon CloudWatch monitors your AWS resources and the applications that you run on AWS in near-real time. You can monitor Amazon Location resources using CloudWatch, which collects raw data and processes metrics into meaningful statistics in near-real time. You can view historical information for up to 15 months, or search metrics to view in the Amazon CloudWatch console for more perspective about your Amazon Location resources. You can also set alarms by defining thresholds, and send notifications or take actions when those thresholds are met.

For more information, see the Amazon CloudWatch User Guide

Amazon Location Service metrics exported to Amazon CloudWatch

Metrics are time-ordered data points that are exported to CloudWatch. A dimension is a name/value pair that identifies the metric. For more information, see Using CloudWatch metrics and CloudWatch dimensions in the Amazon CloudWatch User Guide.

The following are metrics that Amazon Location Service exports to CloudWatch in the AWS/Location namespace.

Metric Description

CallCount

The number of calls made to a given API endpoint.

Valid Dimensions: Amazon Location Service API names

Valid Statistic: Sum

Units: Count

ErrorCount

The number of error responses from calls made to a given API endpoint.

Valid Dimensions: Amazon Location Service API names

Valid Statistic: Sum

Units: Count

SuccessCount

The number of successful calls made to a given API endpoint.

Valid Dimensions: Amazon Location Service API names

Valid Statistic: Sum

Units: Count

CallLatency

The amount of time the operation takes to process and return a response when a call is made to a given API endpoint.

Valid Dimensions: Amazon Location Service API names

Valid Statistic: Average

Units: Milliseconds

Create CloudWatch alarms for Amazon Location Service metrics

You can use CloudWatch to set alarms on your Amazon Location Service metrics. For example, you can create an alarm in CloudWatch to send an email whenever an error count spike occurs.

The following topics give you a high-level overview of how to set alarms using CloudWatch. For detailed instructions, see Using Alarms in the Amazon CloudWatch User Guide.

To set alarms using the CloudWatch console

  1. Open the CloudWatch console at https://console.aws.amazon.com/cloudwatch/.

  2. In the navigation pane, choose Alarm.

  3. Choose Create Alarm.

  4. Choose Select metric.

  5. On the All metrics tab, select the Amazon Location namespace.

  6. Select a metric category.

  7. Find the row with the metric you want to create an alarm for, then select the check box next to this row.

  8. Choose Select metric.

  9. Under Metric, fill in the values .

  10. Specify the alarm Conditions .

  11. Choose Next.

  12. If you want to send a notification when the alarm conditions are met:

    • Under Alarm state trigger, select the alarm state to prompt a notification to be sent.

    • Under Select an SNS topic, choose Create new topic to create a new Amazon Simple Notification Service (Amazon SNS) topic. Enter the topic name and the email to send the notification to.

    • Under Send a notification to enter additional email addresses to send the notification to.

    • Choose Add notification. This list is saved and appears in the field for future alarms.

  13. When done, choose Next.

  14. Enter a name and description for the alarm, then choose Next.

  15. Confirm the alarm details, then choose Next.

Note

When creating a new Amazon SNS topic, you must verify the email address before a notification can be sent. If the email is not verified, the notification will not be received when an alarm is initiated by a state change.

For more information about how to set alarms using the CloudWatch console, see Create an Alarm that Sends Email in the Amazon CloudWatch User Guide.

Use CloudWatch to monitor usage against quotas

You can create Amazon CloudWatch alarms to notify you when your utilization of a given quota exceeds a configurable threshold. This enables you to recognize when you are close to your quota limits, and either adapt your utilization to avoid cost overruns, or request a quota increase, if needed. For information about how to use CloudWatch to monitor quotas, see Visualizing your service quotas and setting alarms in the Amazon CloudWatch User Guide.

CloudWatch metric examples for Amazon Location Service

You can use the GetMetricData API to retrieve metrics for Amazon Location.

  • For example, you can monitor CallCount and set an alarm for when a drop in number occurs.

    Monitoring the CallCount metrics for SendDeviceLocation can help give you perspective on tracked assets. If the CallCount drops, it means that tracked assets, such as a fleet of trucks, have stopped sending their current locations. Setting an alarm for this can help notify you an issue has occurred.

  • For another example, you can monitor ErrorCount and set an alarm for when a spike in number occurs.

    Trackers must be associated with geofence collections in order for device locations to be evaluated against geofences. If you have a device fleet that requires continuous location updates, seeing the CallCount for BatchEvaluateGeofence or BatchPutDevicePosition drop to zero indicates that updates are no longer flowing.

The following is an example output for GetMetricData with the metrics for CallCount and ErrorCount for creating map resources.
