Protocol Integration

DynamoDB protocol metrics (throughput, latency, errors) are captured out-of-the-box by collectors running with EPOCH_ANALYSIS_DEPTH=layer7 set in their configuration.

DynamoDB infrastructure metrics can be viewed using AWS CloudWatch integration.

Amazon DynamoDB is a fast and flexible NoSQL database service for all applications that need consistent, single-digit millisecond latency at any scale. It is a fully managed cloud database and supports both document and key-value store models. Its flexible data model and reliable performance make it a great fit for mobile, web, gaming, ad tech, IoT, and many other applications.

Attributes

For DynamoDB, below attributes can be used in filters and group by operations in analytics within alerts, dashboards, etc.

Metric	Description	Value / Example
dynamodb.Key.x.x	A multi-valued dimension that tracks the contents of primary key in DynamoDB transactions	"Key": { "ForumName": { "S": "Amazon DynamoDB" }, "Subject": { "S": "How do I update multiple items?" } }
dynamodb.action	The database action	CreateTable, GetItem, Query etc.
dynamodb.error.code	Numeric error code	In this error message: ERROR 1146 (42S02): Table 'test.no_such_table' doesn't exist, the error code is 1146.
dynamodb.error.message	Textual description of the error	In this error message: ERROR 1146 (42S02): Table 'test.no_such_table' doesn't exist, error string is Table 'test.no_such_table' doesn't exist
dynamodb.httpstatuscode	HTTP status code	200, 400, 500
dynamodb.table	The dynamodb table

There are some attributes that are common across the integrations. The description to the relevant attributes for this integration can be found here: shared attributes
