Should be used in recording rules and alerts.įor certain metrics which update relatively rarely, such as from S3, An expression such asĪws_elb_request_count_sum offset 10m will allow you to access the data, and Time, you will not see data from CloudWatch.
In practice this means that if you evaluate an instant vector at the current

TimestampsĬloudWatch has been observed to sometimes take minutes for reported values to converge. The CloudWatch Exporter mirrors this behavior, so you should refer to the Cloudwatch documentation to find out if your metric is always reported or not. CloudWatch doesn't always report dataĬloudwatch reports data either always or only in some cases, example only if there is a non-zero value. If the metrics label values are "unknown" the build information scrap failed. Build Info MetricĬloudwatch_exporter_build_info is a default cloudwatch exporter metric that contains the currentĬloudwatch exporter version and release date as label values. Labels referencing the current build version and build release date. Occurred during the scrape, and cloudwatch_exporter_scrape_duration_secondsĬontains the duration of that scrape. In addition cloudwatch_exporter_scrape_error will be non-zero if an error * on(load_balancer_name) group_left(tag_MyOtherKey)

The above config will export time series such as Boolean Emit warning if the exporter cannot determine what metrics to request Number of seconds to cache the result of calling the ListMetrics API. Boolean (experimental) Use GetMetricData API to get metrics instead of GetMetricStatistics. For some metrics which are updated very infrequently (such as S3/BucketSize), Prometheus may refuse to scrape them if this is set to true (see #100). Boolean for whether to set the Prometheus metric timestamp as the original Cloudwatch timestamp. Useful for cases such as Billing metrics that are only set every few hours. Used to avoid collecting data that has not fully converged. Extended statistics currently include percentiles in the form pN or pN.N. A list of extended statistics to retrieve. Defaults to all statistics unless extended statistics are requested. A list of statistics to retrieve, values can include Sum, SampleCount, Minimum, Maximum, Average. For the current metric, specify which CloudWatch dimension maps to the ARN resource ID. Where resource_type could be an empty string, like in S3 case: resource_type_selection: "s3:". resource_type_selection should be comprised as service:resource_type, as per the resource group tagging API. Specify a map from a tag key to a list of tag values to apply tag filtering on resources from which metrics will be gathered. A tag configuration to filter on, based on mapping from the tagged resource ID to a CloudWatch dimension. Specify a map from the dimension name to a list of regexes that will be applied to select from that dimension. Which dimension values to filter on with a regular expression. Specify a map from the dimension name to a list of values to select from that dimension. Run aws cloudwatch list-metrics to find out which dimensions you need to include for your metric. This should contain exactly all the dimensions available for a metric. A list of CloudWatch metrics to retrieve and export Useful for retrieving cross account metrics. If none is provided, an attempt will be made to determine the region from the default region provider chain. Note: A configuration builder can be found here. Note: configuration examples for different namespaces can be found in examples directory Resource_type_selection: "elasticloadbalancing:loadbalancer" ConfigurationĪn example with common options and aws_dimension_select:Īws_dimensions: The tag:GetResources IAM permission is also required to use the aws_tag_select feature. The cloudwatch:ListMetrics, cloudwatch:GetMetricStatistics and cloudwatch:GetMetricData IAM permissions are required. This includes the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment Which offers a variety of ways to provide credentials.
