       svcs -n [FMRI] ...


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

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


       The svcs [-aHpv?] form of the command prints one-line  status  listings
       for  service  instances  specified  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
       below.


       The svcs  -d | -D form of the command prints one-line  status  listings
       for  the  dependencies or dependents of the service instances specified
       by the arguments.


       The svcs  -L form of the command prints log  contents.  For  additional
       information, see Options below.


       The svcs  -l form of the command prints detailed information about spe‐
       cific services and instances.


       The svcs  -n form of the command prints  notification  parameters.  For
       additional information, see Options below.


       The  svcs   -x  form  of  the  command  explains  the states of service
       instances. For each argument, a block of human-readable  text  is  dis‐
       played  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(8) command.

OPTIONS
       The following options are supported:

       -?

           Displays an extended usage message, including column specifiers.


       -a

           Show  all  services,  including  those which are disabled or incom‐
           plete. Additional  information  regarding  incomplete  services  is
           available using svcs  -x <service>.

           This option has no effect if services are selected.


       -d

           Lists  the  services or service instances upon which the given ser‐
           vice instances depend.


       -D

           Lists the service instances that depend on the  given  services  or
           service instances.


       -H

           Omits the column headers.


       -L

           Prints  the path to the logfile created by the service restarter of
           the selected service instances.

           With -x, either print the logfile beginning after the  last  occur‐
           rence  of  log message for a method exit without errors or the last
           10 lines of the logfile based on which is smaller at the end of the
           explanation  for that service instance. If a log message for method
           exit without errors is present in the last  line  of  the  logfile,
           print the last 5 lines of the logfile.

           With -v, if only a single service instance match the input, it will
           print the content of logfile. If multiple service  instances  match
           the  input, print the last 10 lines of the logfile for each service
           instance.


       -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
           separated 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 separated by  a  forward
               slash  (/).  Next,  each  entity  and  its state is listed. See
               smf(7) for information about states. In addition to  the  stan‐
               dard  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(7)).


               multiple

                   The entity is a service with multiple instances.

               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 dependencies, it can consider the
                   dependency to be unsatisfied. svcadm refresh forces  depen‐
                   dency re-evaluation.


               unknown

                   stat(2) failed for a reason other than ENOENT.

               See smf(7) 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 (temporary).

               A  service might be temporarily disabled because an administra‐
               tor has run svcadm disable -t, used svcadm milestone, or booted
               the system to a specific milestone. See svcadm(8) for details.



       -n

           Prints  notification  parameters.  See smf(7). It always prints the
           FMA events notification parameters and the  system-wide  SMF  state
           transition  notification parameters, regardless of the FMRI or pat‐
           tern selected.


       -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
           which:

               o      are enabled, but are not running.


               o      are preventing another enabled service from running.


               o      are in the degraded state.



OPERANDS
       The following operands are supported:

       FMRI

           A fault management resource identifier (FMRI) that specifies one or
           more instances (see smf(7)). FMRIs can be abbreviated by specifying
           the instance name, or the trailing portion of the service name. For
           example, given the FMRI:


             svc:/network/smtp:sendmail

           The following are valid abbreviations:


             sendmail
             :sendmail
             smtp
             smtp:sendmail
             network/smtp



           The following are invalid abbreviations:


             mail
             network
             network/smt

           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
           according  to  the  globbing  rules described by fnmatch(7). If the
           pattern does not begin with svc: and is not a  glob  pattern,  then
           svc:/  is  prepended.  If the pattern is a glob pattern, it is used
           unmodified for matching.

           The following is a typical example of a glob pattern:


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

           Note that changing the pattern to remove the leading  glob  results
           in different behavior:


             qexample% svcs keyserv\*
             svcs: Pattern 'svc:/keyserv:*' doesn't match any instances
             STATE          STIME    FMRI




       FMRI-instance

           An FMRI that specifies an instance.


COLUMNS
       Column names are case insensitive. The default output format is equiva‐
       lent 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(7)):


           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(7) 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(7) 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.


       ASTATE

           The auxiliary state of the service instance, if applicable. Service
           instances  which have no auxiliary state will display a '-' charac‐
           ter in this column.


       LRUN

           The  last  time  a  periodic  service  instance  has  run.  Service
           instances  that  are not periodic, and have no last execution, will
           display a '-' character in this column.

           See svc.periodicd(8) for an explanation of periodic services.


       NRUN

           The next time a periodic service instance is scheduled to run. Ser‐
           vice  instances  that are not periodic do not have a next scheduled
           run and will display a '-' character in this column.

           See svc.periodicd(8) for an explanation of periodic services.

         ...



       Example 2 Listing All Local Instances



       This example lists all local instances of the service1 service.


         example% svcs -o state,nstate,fmri service1
         STATE        NSTATE        FMRI
         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
         STATE          NSTATE        STIME    CTID   FMRI
         online         -             Aug_09        - svc:/network/rpc/rstat:udp



       Example 4 Listing Detailed Information



       This example lists detailed information about  all  instances  of  sys‐
       tem/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
         contract_id
         dependency   require_all/error svc:/network/rpc/bind (online)



       Example 5 Listing Processes


         example% svcs -p sendmail
         STATE          STIME    FMRI
         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 ser‐
       vice 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://support.oracle.com/msg/SMF-8000-05
            See: lpsched(8)
         Impact: 2 dependent services are not running. (Use -v for list.)




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


         example$ svcs nfs/client
         STATE          STIME    FMRI
         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://support.oracle.com/msg/SMF-8000-GE
           Path: svc:/network/nfs/client:default
                   svc:/network/nfs/nlockmgr:default
                     svc:/network/nfs/status:default
            See: man -M /usr/share/man -s 8 mount_nfs
            See: /var/svc/log/network-nfs-client:default.log
         Impact: This service is not running.
