       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]...


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


       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 be‐
       low.


       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 in‐
       stances. 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(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.


       -i

           Displays date/time in the legacy non-parsable format instead of ISO
           8601-1:2019.


       -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 se‐
           lected 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  de‐
               scriptions:


               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  en‐
               abled  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:


             example% svcs \*ssh\*
             STATE          STIME               FMRI
             online         2022-03-14T10:25:22 svc:/network/ssh:default

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

             example% svcs ssh\*
             svcs: Pattern 'svc:/ssh:*' 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 hy‐
           phen (‐) 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  in‐
           stances in transition, unless the NSTA or NSTATE column is also be‐
           ing displayed.

           See smf(7) for an explanation of service states.


       STIME

           The  date  and time (in ISO 8601-1:2019 format) the service entered
           the state. The legacy, non-parsable, format is displayed  when  the
           -i  option  is  provided or when SMF_SVCS_DATA_FMT=legacy is set in
           the environment.


       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  (in ISO 8601-1:2019 format) a periodic service in‐
           stance has run. Service instances that are not periodic,  and  have
           no last execution, will display a '-' character in this column. The
           legacy,  non-parsable,  format  is  displayed when the -i option is
           provided or when SMF_SVCS_DATA_FMT=legacy is set  in  the  environ‐
           ment.

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


       NRUN

           The  next  time  (in ISO 8601-1:2019 format) a periodic service in‐
           stance is scheduled to run. Service instances that are not periodic
           do not have a next scheduled run and will display a  '-'  character
           in  this column. The legacy, non-parsable, format is displayed when
           the -i option is provided or when SMF_SVCS_DATA_FMT=legacy  is  set
           in the environment.

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

       Example 5 Listing Processes


         example% svcs -p sendmail

                        2022-03-14T10:25:46      1489 sendmail


       Example 6 Explaining Service States Using svcs -x



       (a) In this example, svcs  -x has  identified  that  the  identity:cert
       service  being  in  maintenance is the root cause of two services which
       are enabled but not online. svcs  -xv shows  that  those  services  are
       system/rad:remote  and system/webui. This situation can be rectified by
       either clearing identity:cert or disabling system/rad:remote  and  sys‐
       tem/webui.


         example% svcs -x
         svc:/system/identity:cert (System identity (X.509 certificate))
          State: maintenance since 2022-04-13T12:18:35
         Reason: Maintenance requested by an administrator.
            See: http://support.oracle.com/msg/SMF-8000-63
            See: identity(7)
            See: /var/svc/log/system-identity:cert.log
         Impact: 2 dependent services are not running.  (Use -v for list.)



         example% svcs -xv
         svc:/system/identity:cert (System identity (X.509 certificate))
          State: maintenance since 2022-04-13T12:18:35
         Reason: Maintenance requested by an administrator.
            See: http://support.oracle.com/msg/SMF-8000-63
            See: man -M /usr/share/man -s 7 identity
            See: /var/svc/log/system-identity:cert.log
         Impact: 2 dependent services are not running:
                 svc:/system/rad:remote
                 svc:/system/webui/server:default




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


         example$ svcs nfs/client
         STATE          STIME               FMRI
         offline       2022-03-14T10:25:12 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

           When set to legacy the legacy, non-parsable,  date/time  format  is
           used  instead  of  ISO  8601-1:2019.  For  the legacy format if the

           is displayed. The value of iso8601 can be set to explicitly request
