--- title: AWS ALB/NLB monitoring integration source: https://docs.newrelic.com/docs/infrastructure/amazon-integrations/aws-integrations-list/aws-albnlb-monitoring-integration --- > #### ⚠️ IMPORTANT > > Enable the [AWS CloudWatch Metric Streams integration](https://docs.newrelic.com/docs/infrastructure/amazon-integrations/aws-integrations-list/aws-metric-stream/) to monitor all CloudWatch metrics from your AWS services, including custom namespaces. Individual integrations are no longer our recommended option. [Amazon Application Load Balancing](http://docs.aws.amazon.com/elasticloadbalancing/latest/application/introduction.html) (ALB) distributes incoming application traffic across multiple targets, such as EC2 instances, in multiple availability zones. [Amazon Network Load Balancer](http://docs.aws.amazon.com/elasticloadbalancing/latest/network/introduction.html) (NLB) distributes incoming traffic across multiple targets, such as Amazon EC2 instances. [New Relic infrastructure integrations](https://docs.newrelic.com/docs/infrastructure/introduction-infra-monitoring) include an integration for reporting your AWS ALB/NLB data to New Relic products. This document explains how to activate this integration and describes the data that can be captured. New Relic also offers an [integration for Amazon's Elastic Load Balancing (ELB) service](https://docs.newrelic.com/docs/infrastructure/amazon-integrations/amazon-integrations/aws-elb-monitoring-integration). ## Activate integration [#activate] To enable this integration, follow standard procedures to [connect AWS services to New Relic](https://docs.newrelic.com/docs/infrastructure/infrastructure-integrations/getting-started/connect-aws-integrations-infrastructure). ## Configuration and polling [#polling] You can change the polling frequency and filter data using [configuration options](https://docs.newrelic.com/docs/integrations/new-relic-integrations/getting-started/configure-polling-frequency-data-collection-cloud-integrations). [Default polling](https://docs.newrelic.com/docs/infrastructure/amazon-integrations/aws-integrations-list/aws-polling-intervals-infrastructure-integrations) information for the AWS ALB/NLB integration: - New Relic polling interval: 5 minutes - Amazon CloudWatch data interval: 1 minute ## View and use data [#find-data] To [view and use your integration data](https://docs.newrelic.com/docs/infrastructure/integrations/find-use-infrastructure-integration-data), go to **[one.newrelic.com > All capabilities](https://one.newrelic.com/all-capabilities) > Infrastructure > AWS** and select one of the AWS ALB integration links. You can [query and explore your data](https://docs.newrelic.com/docs/using-new-relic/data/understand-data/query-new-relic-data) using the `LoadBalancerSample` [event type](https://docs.newrelic.com/docs/data-apis/understand-data/new-relic-data-types/#event-data) within four categories of data: - ALB: Appears in New Relic with `provider` value `Alb`. - NLB: Appears in New Relic with `provider` value `Nlb`. - [ALB target group](http://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-target-groups.html): Appears in New Relic with `provider` value `AlbTargetGroup`. - [NLB target group](https://docs.aws.amazon.com/elasticloadbalancing/latest/network/load-balancer-target-groups.html): Appears in New Relic with `provider` value`NlbTargetGroup`. ## Metric data There are two ALB integration categories of data: ALB and ALB target group. ### ALB metrics [#metric-alb] New Relic Amazon integrations collect the following Amazon ALB data to the provider `Alb`. | Metric | Description | | -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `activeConnectionCount` | The total number of concurrent TCP connections active from clients to the load balancer and from the load balancer to targets. | | `newConnectionCount` | The total number of new TCP connections established from clients to the load balancer and from the load balancer to targets. | | `rejectedConnectionCount` | The number of connections that were rejected because the load balancer had reached its maximum number of connections. | | `processedBytes` | The total number of bytes processed by the load balancer over IPv4 and IPv6. | | `requestCount` | The count of requests processed over IPv4 and IPv6. Requests only increment this metric when the load balancer node was able to select a target. If a request is rejected before a target is choses, it is not reflected. Stats: Sum provides the most value. | | `rulesEvaluated` | The number of rules processed by the load balancer given a request rate averaged over an hour. | | `clientTlsNegotiationErrorCount` | The number of TLS connections initiated by the client that did not establish a session with the load balancer. Possible causes include a mismatch of ciphers or protocols. | | `httpCodeElb5XXCount` | The number of HTTP 5XX server error codes that originate from the load balancer. This count does not include any response codes generated by the targets. | | `httpCodeElb4XXCount` | The number of HTTP 4XX client error codes that originate from the load balancer. Client errors are generated when requests are malformed or incomplete. These requests have not been received by the target. | | `IpV6ProcessedBytes` | The total number of bytes processed by the load balancer over IPv6. | | `IpV6RequestCount` | The number of IPv6 requests received by the load balancer. | | `lambdaTargetProcessedBytes` | The total number of bytes processed by the load balancer for requests to and responses from a Lambda function. | ### ALB target group metrics [#metric-target] Target group data is stored in New Relic in the provider `AlbTargetGroup`. For example, you can use this data to facet error metrics by target group. | Metric | Description | | ------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `requestCount` | The average count of requests that each target in a target group receives. Stats: Only Sum is valid, which represents the average instead of the sum. | | `healthyHostCount` | The number of targets that are considered healthy. | | `unHealthyHostCount` | The number of targets that are considered unhealthy. | | `targetResponseTime` | The time elapsed, in seconds, after the request leaves the load balancer until a response from the target is received. Available statistics: - aws.applicationelb.target_response_time.p90 - aws.applicationelb.target_response_time.p95 - aws.applicationelb.target_response_time.p99 | | `httpCodeTarget2XXCount` | The number of HTTP `2XX` response codes generated by the targets. This does not include any response codes generated by the load balancer. | | `httpCodeTarget3XXCount` | The number of HTTP `3XX` response codes generated by the targets. This does not include any response codes generated by the load balancer. | | `httpCodeTarget4XXCount` | The number of HTTP `4XX` response codes generated by the targets. This does not include any response codes generated by the load balancer. | | `httpCodeTarget5XXCount` | The number of HTTP `5XX` response codes generated by the targets. This does not include any response codes generated by the load balancer. | | `lambdaInternalError` | The number of requests to a Lambda function that failed because of an issue internal to the load balancer or AWS Lambda. | | `lambdaUserError` | The number of requests to a Lambda function that failed because of an issue with the Lambda function. | There are two NLB integration categories of data: NLB and NLB target group. ### NLB metrics [#metric-alb] New Relic Amazon integrations collect the following Amazon NLB data to the provider `Nlb`. | Metric | Description | | -------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `activeFlowCount` | The total number of concurrent flows (or connections) from clients to targets. This metric includes connections in the `SYN_SENT` and `ESTABLISHED` states. TCP connections are not terminated at the load balancer, so a client opening a TCP connection to a target counts as a single flow. | | `activeFlowCountTls` | The total number of concurrent TLS flows (or connections) from clients to targets. This metric includes only connections in the `ESTABLISHED` states. | | `clientTlsNegotiationErrorCount` | The total number of TLS handshakes that failed during negotiation between a client and a TLS listener. | | `consumedLcus` | The number of load balancer capacity units (LCU) used by your load balancer. You pay for the number of LCUs that you use per hour. | | `newFlowCount` | The total number of new flows (or connections) established from clients to targets in the time period. | | `newFlowCountTls` | The total number of new TLS flows (or connections) established from clients to targets in the time period. | | `processedBytes` | The total number of bytes processed by the load balancer, including TCP/IP headers. | | `processedBytesTls` | The total number of bytes processed by TLS listeners. | | `targetTlsNegotiationErrorCount` | The total number of TLS handshakes that failed during negotiation between a TLS listener and a target. | | `tcpClientResetCount` | The total number of reset (RST) packets sent from a client to a target. These resets are generated by the client and forwarded by the load balancer. | | `tcpElbResetCount` | The total number of reset (RST) packets generated by the load balancer. | | `tcpTargetResetCount` | The total number of reset (RST) packets sent from a target to a client. These resets are generated by the target and forwarded by the load balancer. | ### NLB target group metrics [#metric-target] Target group data is stored in New Relic in the provider `NlbTargetGroup`. For example, you can use this data to facet error metrics by target group. | Metric | Description | | -------------------- | ---------------------------------------------------- | | `healthyHostCount` | The number of targets that are considered healthy. | | `unHealthyHostCount` | The number of targets that are considered unhealthy. |
