7.5.2 Monitoring Processor Usage and Load from the Command Line
The shownode metrics cpus command displays the nice value (this value reflects the amount
of time the CPU has spent in user mode with low priority) as well as the user, system, and idle
times (in milliseconds) for each processor on the node from which this command is issued. For
example:
# shownode metrics cpus
Timestamp |Node |CPU# |User |Nice |System |Idle |I/O |IRQ |Soft_IRQ
------------------------------------------------------------------------------------------
date and time stamp |n15 |0 |22200 |222600 |69000 |12061800 |163920 |240 |3180
| |1 |11940 |223200 |35400 |12251280 |7560 |0 |0
| |2 |8220 |223680 |231600 |11625480 |102840 |48840 |288840
| |3 |25440 |200820 |69960 |12176580 |56040 |120 |540
date and time stamp |n16 |0 |21000 |253740 |55020 |9567900 |561960 |180 |5460
| |1 |9780 |266160 |127320 |9806220 |241200 |0 |900

| |3 |25440 |203640 |72480 |9978540 |166020 |120 |540
The shownode metrics cputotals command also displays the nice value as well as the
user, system, and idle times (in milliseconds), and for the node as a whole. For example:
# shownode metrics cputotals
Timestamp |Node |User |Nice |System |Idle |I/O |IRQ |Soft_IRQ
-----------------------------------------------------------------------------------------
date and time stamp |n14 |67860 |870360 |406080 |48115200 |330480 |49320 |292680
date and time stamp |n15 |67560 |952200 |513060 |38707440 |1215240 |52860 |307500
date and time stamp |n16 |2586660 |1460520 |2476500 |124200600 |2032260 |42180 |698520
The shownode metrics load command displays 1-, 5-, and 15-minute processor load averages
for the node on which this command is issued. For example:
# shownode metrics load
Timestamp |Node |1 min |5 min |15 min |# Running |# threads
---------------------------------------------------------------------------
date and time stamp |n14 |0.00 |0.00 |0.04 |1 |73
date and time stamp |n15 |0.00 |0.00 |0.08 |1 |71
date and time stamp |n16 |0.00 |0.10 |0.28 |1 |216
The columns for ar0, ar1, and ar2 indicate the load average for 1 minute, 5 minutes, and 15
minutes, respectively.
7.5.3 Monitoring Memory from the Command Line
The shownode metrics mem command displays memory total and usage information for the
node on which this command is issued. For example:
# shownode metrics mem
Timestamp |Node |Total |Free |Buffer |Shared |TotalHigh |TotalFree
--------------------------------------------------------------------------------------
date and time stamp |n14 |4037620 |3922916 |5864 |0 |0 |0
date and time stamp |n15 |4037608 |2835972 |6720 |0 |0 |0
date and time stamp |n16 |8005316 |107448 |183388 |0 |0 |0
7.5.4 Monitoring Paging and Swap Data from the Command Line
The shownode metrics paging command displays the paging data for the node on which
this command is issued. For example:
# shownode metrics paging
Timestamp |Node |pgpgin |pgpgout |pswpin |pswpout
------------------------------------------------------------------------
date and time stamp |n14 |0 |0 |0 |0
date and time stamp |n15 |0 |0 |0 |0
date and time stamp |n16 |0 |0 |0 |0
The shownode metrics swap command displays swap space total and usage for the node
on which the command is issued. For example:
# shownode metrics swap
Timestamp |Node |Total |Used |Free |Page Cache
---------------------------------------------------------------------------
date and time stamp |n14 |6289408 |40572 |6248836 |70788
