+title: Learn to use PMUV3_PLUGIN to do performance analysis at a code level and analyse hotspots
+
+minutes_to_complete: 60
+
+who_is_this_for: Engineers working on a workload/codebase to carry out performance analysis at code block level.
+
+learning_objectives: 
+    - Get a fine-grained and precise measurement of functions handling a specific task. 
+    - The plugin is grouped into 15 categories also known as bundles, and each bundle has a set of PMU events. The values of the same can be obtained in one shot.   
+    - Apart from raw PMU event values, the backend tool also provides the KPI/metric values like MPKI, stalls, IPC and many more, thus helping in performance analysis tasks. 
+
+prerequisites:
+    - Some familiarity with performance analysis.
