Monitoring the health of infrastructure and services is essential for understanding system performance. However, in large environments, tracking process performance can be challenging due to the sheer volume of processes. Datadog Live Processes now offers Process Tag Rules, which enable users to enrich their systems' end-to-end visibility by deriving tags from a process's command line. This feature allows users to quickly find common issues with groups of processes, track system health by creating metrics and monitors on custom process groups, and enhance their overall process-level observability. With Process Tag Rules, users can create new tags based on the command line configuration of their processes, monitor performance and resource utilization for related processes, and set up metric monitors to alert them when certain thresholds are reached. This feature is available to Datadog customers and offers a 14-day free trial for those who are not already using the platform.
