Datadog has introduced Process Tag Rules, which enable users to enrich their system's end-to-end visibility by deriving tags from a process's command line and creating performance metrics and alerts specific to those tags. This feature allows users to quickly find common issues with groups of processes, track system health, and create custom process groups for more effective monitoring. By using Process Tag Rules, users can gain deeper insights into their infrastructure and services, troubleshoot issues more efficiently, and optimize resource allocation. The feature is available to Datadog customers, including a 14-day free trial for new users.
