3.7.2 Performance Information (Solaris)

This section explains how to collect the performance information necessary when investigate a performance problem in Solaris platform.

• CPU use status
• Network load status
• Memory use status
• I/O status
• Process information

CPU Use Status

Execute the mpstat command to monitor multiple CPU use rate.

mpstat -p [execution time interval (sec.)]  [number of execution]

Remark: The execution will not stop if the number of execution is omitted.

Display Sample:

CPU minf mjf xcal  intr ithr  csw icsw migr smtx  srw syscl  usr sys  wt idl
  0    0   0    1   214  114   25    0    0    0    0    38    0   0   0 100
  1    1   0    1     3    2   31    0    1    0    0    45    0   0   0 100

Remark: CPU use rate = (usr+sys)%

Network Load Status

Execute the netstat command to monitor the network load status.

netstat -in

Display Sample:

  Name  Mtu   Network       Address        Ipkts   Ierrs Opkts   Oerrs Collis
  dr0   1268  192.168.0     192.168.0.1    4340    0     14      0     0     
  eth0  1500  192.169.0     192.169.0.2    4116    0     6748    0     0     
  lo0   9216  127           127.0.0.1      2       0     2       0     0     

Ipkts:Number of received packets
Ierrs:Number of received packets that have errors
Opkts:Number of sent packets
Oerrs:Number of sent packets that have errors
Collis:Number of packets that have a collision

Memory Use Status

Execute the vmstat command to monitor the memory use status.

The amount of memory for swap-in (reading the swap-out data into physical memory) and swap-out (writing the physical memory data into the hard disk) can be examined.

vmstat -S [execution time interval (sec.)]  [number of execution]

Remark: The execution will not stop if the number of execution is omitted.

Display Sample:

kthr      memory            page            disk          faults      cpu
r b w   swap  free  si  so pi po   fr de sr f0 s0 s1 s4   in   sy   cs us sy id
0 0 0 1293368 806752 0   0  0  0    0  0  0  0  0  0  0  217   83   55  0  0 100

si:The amount of memory for swap-in in 1 second (kilobytes)
so:The amount of memory for swap-out in 1 second (kilobytes)

I/O Status

Execute the iostat command to monitor the I/O status if the disk in the director server.

iostat -ctx [execution time interval (sec.)]  [number of execution]

Remark: The execution will not stop if the number of execution is omitted.

Display Sample:

                extended device statistics                      tty         cpu

nfs1       0.0    0.0    0.0    0.0   0.0   0.0    0.1   0   0

Process Information

Execute the ps command to monitor the operating status of the process.

ps -elfy
