Enable this integration to see all your Lex metrics in Datadog. ## Setup{% #setup %} ### Installation{% #installation %} If you haven't already, set up the [Amazon Web Services integration](https://docs.datadoghq.com/integrations/amazon_web_services/) first. ### Metric collection{% #metric-collection %} 1. In the [AWS integration page](https://app.datadoghq.com/integrations/amazon-web-services), ensure that `Lex` is enabled under the `Metric Collection` tab. 1. Install the [Datadog - Amazon Lex integration](https://app.datadoghq.com/integrations/amazon-lex). ### Log collection{% #log-collection %} #### Enable logging{% #enable-logging %} Configure Amazon Lex to send logs either to a S3 bucket or to CloudWatch. **Note**: If you log to a S3 bucket, make sure that `amazon_lex` is set as *Target prefix*. #### Send logs to Datadog{% #send-logs-to-datadog %} 1. If you haven't already, set up the [Datadog Forwarder Lambda function](https://docs.datadoghq.com/logs/guide/forwarder/). 1. Once the Lambda function is installed, manually add a trigger on the S3 bucket or CloudWatch log group that contains your Amazon Lex logs in the AWS console: - [Add a manual trigger on the S3 bucket](https://docs.datadoghq.com/logs/guide/send-aws-services-logs-with-the-datadog-lambda-function/#collecting-logs-from-s3-buckets) - [Add a manual trigger on the CloudWatch Log Group](https://docs.datadoghq.com/logs/guide/send-aws-services-logs-with-the-datadog-lambda-function/#collecting-logs-from-cloudwatch-log-group) ## Data Collected{% #data-collected %} ### Metrics{% #metrics %} | | | | | **aws.lex.assisted\_slot\_resolution\_model\_access\_denied\_error\_count**(count) | The number of times that Amazon Lex V2 was denied access to Amazon Bedrock.*Shown as error* | | **aws.lex.assisted\_slot\_resolution\_model\_invocation\_count**(count) | The number of times that Amazon Bedrock was invoked.*Shown as invocation* | | **aws.lex.assisted\_slot\_resolution\_model\_system\_error\_count**(count) | The number of times that a 5xx occurred when calling Amazon Bedrock.*Shown as error* | | **aws.lex.assisted\_slot\_resolution\_model\_throttling\_error\_count**(count) | The number of times that Amazon Lex was throttled by Amazon Bedrock.*Shown as throttle* | | **aws.lex.assisted\_slot\_resolution\_resolved\_slot\_count**(count) | The number of times that Amazon Bedrock returned a slot value.*Shown as event* | | **aws.lex.runtime\_kendra\_index\_access\_error**(count) | The number of times that Amazon Lex V2 could not access your Amazon Kendra index.*Shown as error* | | **aws.lex.runtime\_kendra\_latency**(gauge) | The amount of time that it takes Amazon Kendra to respond to a request from the AMAZON.KendraSearchIntent.*Shown as millisecond* | | **aws.lex.runtime\_kendra\_success**(count) | The number of successful requests from the AMAZON.KendraSearchIntent to your Amazon Kendra index.*Shown as request* | | **aws.lex.runtime\_kendra\_system\_errors**(count) | The number of times that Amazon Lex V2 couldn't query the Amazon Kendra index.*Shown as error* | | **aws.lex.runtime\_kendra\_throttled\_events**(count) | The number of times Amazon Kendra throttled requests from the AMAZON.KendraSearchIntent.*Shown as throttle* | | **aws.lex.missed\_utterance\_count**(count) | The number of utterances that were not recognized in the specified period.*Shown as event* | | **aws.lex.runtime\_concurrency**(gauge) | The number of concurrent connections in the specified time period.*Shown as connection* | | **aws.lex.runtime\_invalid\_lambda\_responses**(count) | The number of invalid AWS Lambda responses in the specified period.*Shown as response* | | **aws.lex.runtime\_lambda\_errors**(count) | The number of AWS Lambda runtime errors in the specified time period.*Shown as error* | | **aws.lex.runtime\_polly\_errors**(count) | The number of invalid Amazon Polly responses in the specified time period.*Shown as error* | | **aws.lex.runtime\_request\_count**(count) | The number of runtime requests in the specified time period.*Shown as request* | | **aws.lex.runtime\_request\_length**(gauge) | Total length of a conversation with a Amazon Lex V2 bot.
