Changes SDK update for new Metric Streams feature
Changes Update to SDK to support label time zones in CloudWatch GetMetricData
Changes AWS CloudWatch ListMetrics now supports an optional parameter (RecentlyActive) to filter results by only metrics that have received new datapoints in the past 3 hours. This enables more targeted metric data retrieval through the Get APIs
Changes Amazon CloudWatch Contributor Insights adds support for tags and tagging on resource creation.
Changes Introducing Amazon CloudWatch Composite Alarms
Changes Updating DescribeAnomalyDetectors API to return AnomalyDetector Status value in response.
Changes This release adds a new feature called "Contributor Insights". "Contributor Insights" supports the following 6 new APIs (PutInsightRule, DeleteInsightRules, EnableInsightRules, DisableInsightRules, DescribeInsightRules and GetInsightRuleReport).
Changes New Period parameter added to MetricDataQuery structure.
Changes This release adds three new APIs (PutAnomalyDetector, DeleteAnomalyDetector, and DescribeAnomalyDetectors) to support the new feature, CloudWatch Anomaly Detection. In addition, PutMetricAlarm and DescribeAlarms APIs are updated to support management of Anomaly Detection based alarms.
Changes Added 3 new APIs, and one additional parameter to PutMetricAlarm API, to support tagging of CloudWatch Alarms.
Changes New Messages parameter for the output of GetMetricData, to support new metric search functionality.
Changes Amazon CloudWatch now supports alarms on metric math expressions.
Changes Amazon CloudWatch adds the ability to request png image snapshots of metric widgets using the GetMetricWidgetImage API.
Changes Amazon CloudWatch adds the ability to publish values and counts using PutMetricData
Changes The new GetMetricData API enables you to collect batch amounts of metric data and optionally perform math expressions on the data. With one GetMetricData call you can retrieve as many as 100 different metrics and a total of 100,800 data points.
Changes With this launch, you can now create a CloudWatch alarm that alerts you when M out of N datapoints of a metric are breaching your predefined threshold, such as three out of five times in any given five minutes interval or two out of six times in a thirty minutes interval. When M out of N datapoints are not breaching your threshold in an interval, the alarm will be in OK state. Please note that the M datapoints out of N datapoints in an interval can be of any order and does not need to be consecutive. Consequently, you can now get alerted even when the spikes in your metrics are intermittent over an interval.
Changes We are excited to announce the availability of APIs and CloudFormation support for CloudWatch Dashboards. You can use the new dashboard APIs or CloudFormation templates to dynamically build and maintain dashboards to monitor your infrastructure and applications. There are four new dashboard APIs - PutDashboard, GetDashboard, DeleteDashboards, and ListDashboards APIs. PutDashboard is used to create a new dashboard or modify an existing one whereas GetDashboard is the API to get the details of a specific dashboard. ListDashboards and DeleteDashboards are used to get the names or delete multiple dashboards respectively. Getting started with dashboard APIs is similar to any other AWS APIs. The APIs can be accessed through AWS SDK or through CLI tools.
Changes Amazon Web Services announced the immediate availability of two additional alarm configuration rules for Amazon CloudWatch Alarms. The first rule is for configuring missing data treatment. Customers have the options to treat missing data as alarm threshold breached, alarm threshold not breached, maintain alarm state and the current default treatment. The second rule is for alarms based on percentiles metrics that can trigger unnecassarily if the percentile is calculated from a small number of samples. The new rule can treat percentiles with low sample counts as same as missing data. If the first rule is enabled, the same treatment will be applied when an alarm encounters a percentile with low sample counts.
Changes Amazon CloudWatch now supports Percentiles as a statistical function.
