Amazon CloudWatch Logs and Metrics

Amazon CloudWatch Logs and Metrics Destination Plugin

Amazon CloudWatch is a monitoring and observability service provided by Amazon Web Services (AWS). CloudWatch Logs allows you to monitor, store, and access log files from your EC2 instances, CloudTrail, Lambda, and other AWS resources. With CloudWatch Metrics, you can collect and analyze metric data from your resources to gain insights into their performance and health.

The CloudWatch Destination Plugin in Calyptia Core allows you to easily configure your pipeline to stream your log data and metrics to CloudWatch Logs and Metrics respectively.

Configuration Parameters

The following are configuration Parameters for Amazon CloudWatch Logs and Metrics Destination Plugin.

Key	Description
Region	The AWS region to send your logs or metrics to
CloudWatch Log Group Name	CloudWatch Log Group Name
CloudWatch Log Stream Name	CloudWatch Log Stream Name; Not compatible with Log Stream Prefix

The following are AWS Authentication configuration Parameters for Amazon Kinesis Firehouse Destination Plugin.

Key	Description
IAM Role ARN	ARN of an IAM role to assume (ex. for cross account access).
CloudWatch Logs and Metrics API Endpoint	Custom Endpoint for the FirehoSe API
STS API Endpoint	Custom Endpoint for the STS API
External ID for STS API	Specify an external ID for the STS API, can be used with the role_arn parameter if your role requires an external ID.

The following are configuration Parameters for Amazon CloudWatch Logs and Metrics Destination Plugin.

Key	Description
CloudWatch Log Stream Name Prefix	Prefix for CloudWatch Log Stream Name; the tag is appended to the prefix to form the stream name
CloudWatch Log Group Template	Template for CloudWatch Log Group name using record accessor syntax. Plugin falls back to the log_group_name configured if needed.
CloudWatch Log Stream Template	Template for CloudWatch Log Stream name using record accessor syntax. Plugin falls back to the log_stream_name or log_stream_prefix configured if needed.
Number of days to retain logs	If set to a number greater than zero, and newly create log group's retention policy is set to this many days. Valid values are: [1, 3, 5, 7, 14, 30, 60, 90, 120, 150, 180, 365, 400, 545, 731, 1827, 3653]
Log Format	An optional parameter that can be used to tell CloudWatch the format of the data. A value of json/emf enables CloudWatch to extract custom metrics embedded in a JSON payload
Log Key	By default, the whole log record will be sent to CloudWatch. If you specify a key name with this option, then only the value of that key will be sent to CloudWatch. For example, if you are using the Fluentd Docker log driver, you can specify log_key log and only the log message will be sent to CloudWatch.
Enable Auto Retry Requests	Immediately retry failed requests to AWS services once. This option does not affect the normal Fluent Bit retry mechanism with backoff. Instead, it enables an immediate retry with no delay for networking errors, which may help improve throughput when there are transient/random networking issues.
Enable Auto Create Log Group	Automatically create the log group (log streams will always automatically be created)
Metric namespace for CloudWatch EMF logs	Metric namespace for CloudWatch EMF logs
Metric Dimension List	Metric dimensions is a list of lists. If you have only one list of dimensions, put the values as a comma seperated string. If you want to put list of lists, use the list as semicolon seperated strings. If your value is 'd1,d2;d3', we will consider it as [[d1, d2],[d3]].
