How Datadog’s IT team automated monitoring third-party accounts | Datadog

This post details the development of 'Clarity', an internal tool for automating the auditing of third-party SaaS accounts against Workday (HRIS). It outlines the requirements for the tool, including a single source of truth, frequent execution, manual run capability, and integration with common tooling (Slack, Freshservice, Datadog). The solution involves retrieving reports of active users from SaaS applications and Workday, auditing for discrepancies, sending logs and metrics to Datadog, generating Freshservice tickets, logging to DynamoDB, and sending Slack notifications. Specific technical details include using AWS Lambda, Cloudwatch Event Rules, Datadog metrics (gauge and count types) with custom tags, and Datadog Log Management with facets for detailed auditing information.
