Viewing metadata server system statistics

This topic describes how to use standard Linux utilities, which are provided on the metadata server operating system, to view system statistics.

Prerequisites

You must have Administrator privileges to perform this task.

Steps

  1. Use the top command to display, in real time, the most active CPU processes on the system. These statistics include its process ID (PID), memory usage, swap file usage, and uptime (how long it has been running).
    1. Log in to the metadata server.
    2. Enter top at the Linux prompt.
      <servername>:~ # top
  2. Use the vmstat command to display, in real time, the performance information summarized at the system level. These statistics include the number of processes, paging information, and the percentage of CPU activity broken down by user, system, and idle time.
    1. Log in to the metadata server.
    2. Enter vmstat at the Linux prompt.
      <servername>:~ # vmstat
