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
