svcs - report service status
SYNOPSIS
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
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.

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.
