Hubstats Command; Linkstat Command; Gr_Systat Command; Nodeinfo Command - HP Integrity MC990 X User Manual

The Linux utilities include w(1), ps(1), top(1), vmstat(8), iostat(1), and sar(1). You can use
Linux system monitoring utilities on all MC990 X platforms, including Integrity MC990 X systems.
The FS utilities include hubstats, linkstat, nodeinfo, and topology. HPE supports these utilities
on all MC990 X platforms.

hubstats command

The hubstats command monitors NUMAlink traffic, directory cache operations, and global reference
unit (GRU) traffic statistics on MC990 X systems. It is useful as a performance monitoring tool and as a
tool to help you to diagnose and identify faulty hardware. The uvstats library supplies the hubstats
command with statistics from the MC990 X dashboard.

linkstat command

The linkstat command monitors NUMAlink traffic on MC990 X systems. The linkstat command
returns information about packets and Mbytes sent/received on each NUMAlink in the system. It is useful
as a performance monitoring tool and as a tool to help you to diagnose and identify faulty hardware. The
uvstats library supplies the linkstat command with statistics from the MC990 X dashboard.

gr_systat command

The gr_systat command monitors CPU and memory activity on x86 systems. It's graphical output
display includes information about CPU utilization, I/O wait times, IRQs, and memory utilization, both for
the system as a whole and for each node. The gr_systat command is a useful performance monitoring
tool.

nodeinfo command

nodeinfo is a tool for monitoring per-node NUMA memory statistics on MC990 X systems. The
nodeinfo tool reads /sys/devices/system/node/*/meminfo and /sys/devices/system/
node/*/numastat on the local system to gather NUMA memory statistics.
Sample memory statistics from the nodeinfo command are:
MC990X-sys:~ # nodeinfo
