MapR Process Metrics

Every 10 seconds, the collectd service uses a MapR plugin to gather the following MapR process metrics on each node in the cluster.

Name Description Additional Tag(s)
mapr.process.context_switch_involuntary The number of involuntary context switches for MapR processes. An involuntary context switch occurs when a process consumes more CPU time than what it was allocated by the kernel. When an involuntary context switch occurs, the kernel stops a process to provide resources to another process.
  • process_name: Display values for a specified process. Process values: hoststats,mfs,warden,.etc.
mapr.process.context_switch_voluntary The number of voluntary context switches for MapR processes. A voluntary context switch occurs when a process does not require the entire CPU time it was allocated by the kernel or when a process is suspended. When a voluntary context switch occurs, the kernel provides CPU resources to another process.
  • process_name: Display values for a specified process. Process values: hoststats,mfs,warden,.etc.
mapr.process.cpu_percent The percentage of CPU used for MapR processes.
  • process_name: Display values for a specified process. Process values: hoststats,mfs,warden,.etc.
mapr.process.cpu_time.syst The amount of time, measured in seconds, that the process has been in kernel mode.  
mapr.process.cpu_time.user The amount of time, measured in seconds, that the process has been in user mode  
mapr.process.data The amount memory, in MB, used by the data segments of MapR processes.
  • process_name: Display values for a specified process. Process values: hoststats,mfs,warden,.etc.
mapr.process.disk_octets.read The number of bytes read from disk for MapR processes.  
mapr.process.disk_octets.write The number of bytes written to disk for MapR processes.  
mapr.process.disk_ops.read The number of read operations for MapR processes.  
mapr.process.disk_ops.write The number of write operations for MapR processes.  
mapr.process.mem_percent The percentage of memory used for MapR processes.
  • process_name: Display values for a specified process. Process values: hoststats,mfs,warden,.etc.
mapr.process.page_faults.majflt The number of minor MapR process faults that required loading a memory page from disk.
  • process_name: Display values for a specified process. Process values: hoststats,mfs,warden,.etc.
mapr.process.page_faults.minflt The number of major MapR process faults that required loading a memory page from disk.
  • process_name: Display values for a specified process. Process values: hoststats,mfs,warden,.etc.
mapr.process.rss The actual amount of memory, in MB, used by MapR processes.
  • process_name: Display values for a specified process. Process values: hoststats,mfs,warden,.etc.
mapr.process.vm The amount of virtual memory, in MB, used by MapR processes.
  • process_name: Display values for a specified process. Process values: hoststats,mfs,warden,.etc.
