       svcs - report service status

       svcs [-aHpv?] [-o col[,col]]... [-R FMRI-instance]...
	    [-sS col]... [FMRI | pattern]...

       svcs {-d | -D} [-Hpv?] [-o col[,col]]... [-sS col]...
	    [FMRI | pattern] ...

       svcs -l [-v] [FMRI | pattern]...

       svcs -x [-v] [FMRI]...

       The  svcs  command displays information about service instances as recorded in the service
       configuration repository.

       The first form of this command prints one-line status listings for service instances spec-
       ified  by the arguments. Each instance is listed only once. With no arguments, all enabled
       service instances, even if temporarily disabled, are listed  with  the  columns	indicated

       The  second form prints one-line status listings for the dependencies or dependents of the
       service instances specified by the arguments.

       The third form prints detailed information about specific services and instances.

       The fourth form explains the states of service instances. For each argument,  a	block  of
       human-readable  text  is displayed which explains what state the service is in, and why it
       is in that state. With no arguments, problematic services are described.

       Error messages are printed to the standard error stream.

       The output of this command can be used appropriately as input to the svcadm(1M) command.

       The following options are supported:

       -?		   Displays an extended usage message, including column specifiers.

       -a		   Show all services, even disabled ones. This option has  no  effect  if
			   services are selected.

       -d		   Lists  the  services or service instances upon which the given service
			   instances depend.

       -D		   Lists the service instances that depend on the given services or  ser-
			   vice instances.

       -H		   Omits the column headers.

       -l		   (The  letter  ell.)	Displays  all  available  information  about  the
			   selected services and service instances, with  one  service	attribute
			   displayed for each line. Information for different instances are sepa-
			   rated by blank lines.

			   The following specific attributes require further explanation:

			   dependency	 Information  about  a	dependency.  The   grouping   and
					 restart_on  properties are displayed first and are sepa-
					 rated by a forward slash (/). Next, each entity and  its
					 state	is  listed.  See  smf(5)  for  information  about
					 states. In addition to the standard states, each service
					 dependency can have the following state descriptions:

					 absent      No such service is defined on the system.

					 invalid     The  fault  management  resource  identifier
						     (FMRI) is invalid (see smf(5)).

					 multiple    The  entity  is  a  service  with	 multiple

					 File  dependencies  can  only	have one of the following
					 state descriptions:

					 absent     No such file on the system.

					 online     The file exists.

						    If the file did not exist the last time  that
						    svc.startd	evaluated the service's dependen-
						    cies, it can consider the  dependency  to  be
						    unsatisfied. svcadm refresh forces dependency

					 unknown    stat(2)  failed  for  a  reason  other   than

					 See  smf(5)  for  additional details about dependencies,
					 grouping, and restart_on values.

			   enabled	 Whether the service is enabled or not, and whether it is
					 enabled  or  disabled temporarily (until the next system
					 reboot). The former  is  specified  as  either  true  or
					 false,  and  the latter is designated by the presence of

					 A service  might  be  temporarily  disabled  because  an
					 administrator	has  run  svcadm  disable -t, used svcadm
					 milestone, or booted the system to a specific milestone.
					 See svcadm(1M) for details.

       -o col[,col]...	   Prints  the	specified  columns. Each col should be a column name. See
			   COLUMNS below for available columns.

       -p		   Lists processes associated  with  each  service  instance.  A  service
			   instance can have no associated processes. The process ID, start time,
			   and command name (PID, STIME, and CMD fields from ps(1)) are displayed
			   for each process.

       -R FMRI-instance    Selects  service  instances	that  have  the given service instance as
			   their restarter.

       -s col		   Sorts output by column. col should be a column name. See COLUMNS below
			   for available columns. Multiple -s options behave additively.

       -S col		   Sorts by col in the opposite order as option -s.

       -v		   Without  -x	or  -l,  displays  verbose columns: STATE, NSTATE, STIME,
			   CTID, and FMRI.

			   With -x, displays extra information for each explanation.

			   With -l, displays user-visible properties in property groups  of  type
			   application and their description.

       -x		   Displays explanations for service states.

			   Without  arguments,	the  -x  option  explains  the states of services

			       o      are enabled, but are not running.

			       o      are preventing another enabled service from running.

       The following operands are supported:

       FMRI		A fault management resource identifier (FMRI) that specifies one or  more
			instances  (see  smf(5)).  FMRIs  can  be  abbreviated	by specifying the
			instance name, or the trailing portion of the service name. For  example,
			given the FMRI:


			The following are valid abbreviations:


			The following are invalid abbreviations:


			If  the  FMRI  specifies  a  service,  then  the  command  applies to all
			instances of that service, except when used with the -D option.

			Abbreviated forms of FMRIs are	unstable,  and	should	not  be  used  in
			scripts or other permanent tools.

       pattern		A  pattern that is matched against the FMRIs of service instances accord-
			ing to the "globbing" rules described by fnmatch(5). If the pattern  does
			not  begin with svc:, then svc:/ is prepended. The following is a typical
			example of a glob pattern:

			  qexample% svcs \*keyserv\*
			  disabled	 Aug_02    svc:/network/rpc/keyserv:default

       FMRI-instance	An FMRI that specifies an instance.

       Column names are case  insensitive.  The  default  output  format  is  equivalent  to  "-o
       state,stime,fmri". The default sorting columns are STATE, STIME, FMRI.

       CTID	 The  primary  contract ID for the service instance. Not all instances have valid
		 primary contract IDs.

       DESC	 A brief description of the service, from its template element. A  service  might
		 not  have  a description available, in which case a hyphen (-) is used to denote
		 an empty value.

       FMRI	 The FMRI of the service instance.

       INST	 The instance name of the service instance.

       NSTA	 The abbreviated next state of the service instance, as given in the  STA  column
		 description.  A  hyphen  denotes that the instance is not transitioning. Same as
		 STA otherwise.

       NSTATE	 The next state of the service. A hyphen is used to denote that the  instance  is
		 not transitioning. Same as STATE otherwise.

       SCOPE	 The scope name of the service instance.

       SVC	 The service name of the service instance.

       STA	 The abbreviated state of the service instance (see smf(5)):

		 DGD	degraded

		 DIS	disabled

		 LRC	legacy rc*.d script-initiated instance

		 MNT	maintenance

		 OFF	offline

		 ON	online

		 UN	uninitialized

		 Absent  or  unrecognized states are denoted by a question mark (?) character. An
		 asterisk (*) is appended for instances in transition, unless the NSTA or  NSTATE
		 column is also being displayed.

		 See smf(5) for an explanation of service states.

       STATE	 The  state  of  the  service  instance. An asterisk is appended for instances in
		 transition, unless the NSTA or NSTATE column is also being displayed.

		 See smf(5) for an explanation of service states.

       STIME	 If the service instance entered the current state within the last 24 hours, this
		 column  indicates  the time that it did so. Otherwise, this column indicates the
		 date on which it did so, printed with underscores (_) in place of blanks.

       Example 1 Displaying the Default Output

       This example displays default output:

	 example% svcs
	 legacy_run	13:25:04 lrc:/etc/rc3_d/S42myscript
	 online 	13:21:50 svc:/system/svc/restarter:default
	 online 	13:25:03 svc:/milestone/multi-user:default
	 online 	13:25:07 svc:/milestone/multi-user-server:default

       Example 2 Listing All Local Instances

       This example lists all local instances of the service1 service.

	 example% svcs -o state,nstate,fmri service1
	 online       - 	    svc:/service1:instance1
	 disabled     - 	    svc:/service1:instance2

       Example 3 Listing Verbose Information

       This example lists verbose information.

	 example% svcs -v network/rpc/rstat:udp
	 online 	-	      Aug_09	    - svc:/network/rpc/rstat:udp

       Example 4 Listing Detailed Information

       This example lists detailed information about all instances of system/service3. Additional
       fields can be displayed, as appropriate to the managing restarter.

	 example% svcs -l network/rpc/rstat:udp

	 fmri	      svc:/network/rpc/rstat:udp
	 enabled      true
	 state	      online
	 next_state   none
	 restarter    svc:/network/inetd:default
	 dependency   require_all/error svc:/network/rpc/bind (online)

       Example 5 Listing Processes

	 example% svcs -p sendmail
	 online 	13:25:13 svc:/network/smtp:sendmail
			13:25:15   100939 sendmail
	 13:25:15   100940 sendmail

       Example 6 Explaining Service States Using svcs -x

       (a)  In	this example, svcs -x has identified that the print/server service being disabled
       is the root cause of two services which are enabled but not online. svcs  -xv  shows  that
       those  services	are print/rfc1179 and print/ipp-listener. This situation can be rectified
       by either enabling print/server or disabling rfc1179 and ipp-listener.

	 example% svcs -x
	 svc:/application/print/server:default (LP print server)
	  State: disabled since Mon Feb 13 17:56:21 2006
	 Reason: Disabled by an administrator.
	    See: http://sun.com/msg/SMF-8000-05
	    See: lpsched(1M)
	 Impact: 2 dependent services are not running. (Use -v for list.)

       (b) In this example, NFS is not working:

	 example$ svcs nfs/client
	 offline	16:03:23 svc:/network/nfs/client:default

       (c) The following example shows that the problem  is  nfs/status.  nfs/client  is  waiting
       because it depends on nfs/nlockmgr, which depends on nfs/status:

	 example$ svcs -xv nfs/client
	 svc:/network/nfs/client:default (NFS client)
	  State: offline since Mon Feb 27 16:03:23 2006
	 Reason: Service svc:/network/nfs/status:default
		 is not running because a method failed repeatedly.
	    See: http://sun.com/msg/SMF-8000-GE
	   Path: svc:/network/nfs/client:default
	    See: man -M /usr/share/man -s 1M mount_nfs
	    See: /var/svc/log/network-nfs-client:default.log
	 Impact: This service is not running.

       The following exit values are returned:

       0    Successful command invocation.

       1    Fatal error.

       2    Invalid command line options were specified.

       See attributes(5) for descriptions of the following attributes:

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWcsu			   |
       |Interface Stability	     |See below.		   |

       Screen output is Uncommitted. The invocation is Committed.
