1. Check memory usage and CPU usage

    sar - system activity reporter

     -r              Reports unused memory pages and disk blocks:



                     freemem                 average pages avail-

                                             able     to     user

                                             processes.



                     freeswap                disk  blocks  avail-

                                             able  for page swap-

                                             ping.



     -u              Reports CPU utilization (the default):



                     %usr, %sys, %wio, %idle



                         portion of time running  in  user  mode,

                         running  in  system mode, idle with some

                         process waiting for block I/O, and  oth-

                         erwise idle.



                     If run in a non-global zone  and  the  pools

                     facility  is  active,  these  values reflect

                     activity on the processors of the  processor

                     set of the pool to which the zone is bound.



     -v              Reports  status  of  process,  i-node,  file

                     tables:



                     proc-sz, inod-sz, file-sz, lock-sz



                         entries/size for each  table,  evaluated

                         once at sampling point.



                     ov



                         overflows that  occur  between  sampling

                         points for each table.

e.g.

sar -r -f sa06 | less sar -u -f sa06 | less 

2. prstat

3. vmstat

4. svcs -xv [process name]

     -v                  Without -x,  displays  verbose  columns:

                         STATE, NSTATE, STIME, CTID, and FMRI.



                         With -x, displays extra information  for

                         each explanation.





     -x                  Displays   explanations   for    service

                         states.



                         Without   arguments,   the   -x   option

                         explains the states of services which:



                             o    are enabled, but are  not  run-

                                  ning.



                             o    are preventing another  enabled

                                  service from running.

e.g.

solaris-52c% svcs -xv

svc:/application/management/snmpdx:default (Sun Solstice Enterprise Master Agent)

 State: disabled since September 28, 2011 03:50:55 PM CST

Reason: Disabled by an administrator.

   See: http://sun.com/msg/SMF-8000-05

   See: man -M /usr/share/man/ -s 1M snmpdx

Impact: 1 dependent service is not running:

        svc:/application/management/dmi:default



solaris-52c% svcs -xv cron

svc:/system/cron:default (clock daemon (cron))

 State: online since September 28, 2011 03:56:07 PM CST

   See: man -M /usr/share/man -s 1M cron

   See: man -M /usr/share/man -s 1 crontab

   See: /var/svc/log/system-cron:default.log

Impact: None.
