List of Plugins

The intel_rdt plugin collects information provided by monitoring features of Intel Resource Director Technology (Intel(R) RDT) like Cache Monitoring Technology (CMT), Memory Bandwidth Monitoring (MBM). CMT and MBM are features that allows an operating system (OS) or Hypervisor/virtual machine monitor (VMM) to determine the usage of cache and memory bandwidth by applications running on the platform. Using these monitoring technologies, the intel_rdt plugin collects the following metrics:

  • LLC - last level cache occupancy (CMT)
  • MBL - the bandwidth of accessing memory associated with the local socket (MBM)
  • MBR - the bandwidth of accessing the remote socket (MBM)
  • IPC - instructions per clock

For a full description of available options please refer to the collectd.conf(5) manual page.
