DESCRIPTION
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 ser‐
vice instances specified by the arguments. Each instance is listed only
once. With no arguments, all enabled service instances, even if tempo‐
rarily disabled, are listed with the columns indicated below.
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.
OPTIONS
The following options are supported:
-? Displays an extended usage message, including col‐
umn 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 service instances.
-H Omits the column headers.
-l (The letter ell.) Displays all available informa‐
tion 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(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 instances.
File dependencies can only have one
of the following state descriptions:
absent No such file on the sys‐
tem.
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 depen‐
dency to be unsatisfied.
svcadm refresh forces
dependency re-evaluation.
unknown stat(2) failed for a rea‐
son other than ENOENT.
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 speci‐
fied as either true or false, and the
latter is designated by the presence
of (temporary).
A service might be temporarily dis‐
abled 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 col‐
umns.
-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 ser‐
vice instance as their restarter.
-s col Sorts output by column. col should be a column
name. See COLUMNS below for available columns. Mul‐
tiple -s options behave additively.
-S col Sorts by col in the opposite order as option -s.
-v Without -x, displays verbose columns: STATE,
NSTATE, STIME, CTID, and FMRI.
With -x, displays extra information for each expla‐
nation.
-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.
OPERANDS
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:
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(5). If the pattern does not begin with
svc:, then svc:/ is prepended. The following is a typ‐
ical example of a glob pattern:
qexample% svcs \*keyserv\*
STATE STIME FMRI
disabled Aug_02 svc:/network/rpc/keyserv:default
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 ele‐
ment. 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 other‐
wise.
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.
EXAMPLES
Example 1 Displaying the Default Output
This example displays default output:
example% svcs
STATE STIME FMRI
...
legacy_run 13:25:04 lrc:/etc/rc3_d/S42myscript
...
online 13:21:50 svc:/system/svc/restarter: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
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://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
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://sun.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 1M mount_nfs
See: /var/svc/log/network-nfs-client:default.log
Impact: This service is not running.
