Feature Request

We have created a Telegraf input plugin which collects information provided by monitoring features of Intel Resource Director Technology (Intel^® RDT) like Cache Monitoring Technology (CMT), Memory Bandwidth Monitoring (MBM), Cache Allocation Technology (CAT) and Code and Data Prioritization (CDP) Technology provide the hardware framework to monitor and control the utilization of shared resources, like last level cache, memory bandwidth. These technologies comprise Intel’s Resource Director Technology (RDT). As multithreaded and multicore platform architectures emerge, running workloads in single-threaded, multithreaded, or complex virtual machine environment, the last level cache and memory bandwidth are key resources to manage. Intel introduces CMT, MBM, CAT and CDP to manage these various workloads across shared resources.

To gather Intel RDT metrics plugin uses pqos cli tool which is a part of Intel(R) RDT Software Package.

The plugin we have created will be able to expose following metrics:

• Memory Bandwidth on Local NUMA Node
• Memory Bandwidth on Remote NUMA Node
• Total Memory Bandwidth
• L3 Cache Occupancy
• L3 Cache Misses
• Instructions Per Cycle
