Each instance is listed only once. With no arguments, all enabled service instances, even if temporarily disabled, are listed with the columns indicated below. .sp .LP The second form prints one-line status listings for the dependencies or dependents of the service instances specified by the arguments. .sp .LP The third form prints detailed information about specific services and instances. .sp .LP 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. .sp .LP Error messages are printed to the standard error stream. .sp .LP The output of this command can be used appropriately as input to the \fBsvcadm\fR(1M) command. .SH OPTIONS .sp .LP The following options are supported: .sp .ne 2 .na \fB\fB-?\fR\fR .ad .RS 20n Displays an extended usage message, including column specifiers. .RE .sp .ne 2 .na \fB\fB-a\fR\fR .ad .RS 20n Show all services, even disabled ones. This option has no effect if services are selected. .RE .sp .ne 2 .na \fB\fB-d\fR\fR .ad .RS 20n Lists the services or service instances upon which the given service instances depend. .RE .sp .ne 2 .na \fB\fB-D\fR\fR .ad .RS 20n Lists the service instances that depend on the given services or service instances. .RE .sp .ne 2 .na \fB\fB-H\fR\fR .ad .RS 20n Omits the column headers. .RE .sp .ne 2 .na \fB\fB-l\fR\fR .ad .RS 20n (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. .sp The following specific attributes require further explanation: .sp .ne 2 .na \fB\fBdependency\fR\fR .ad .RS 14n Information about a dependency. The grouping and \fBrestart_on\fR properties are displayed first and are separated by a forward slash (\fB/\fR). Next, each entity and its state is listed. See \fBsmf\fR(5) for information about states. In addition to the standard states, each service dependency can have the following state descriptions: .sp .ne 2 .na \fB\fBabsent\fR\fR .ad .RS 12n No such service is defined on the system. .RE .sp .ne 2 .na \fB\fBinvalid\fR\fR .ad .RS 12n The fault management resource identifier (FMRI) is invalid (see \fBsmf\fR(5)). .RE .sp .ne 2 .na \fB\fBmultiple\fR\fR .ad .RS 12n The entity is a service with multiple instances. .RE File dependencies can only have one of the following state descriptions: .sp .ne 2 .na \fB\fBabsent\fR\fR .ad .RS 11n No such file on the system. .RE .sp .ne 2 .na \fB\fBonline\fR\fR .ad .RS 11n The file exists. .sp If the file did not exist the last time that \fBsvc.startd\fR evaluated the service's dependencies, it can consider the dependency to be unsatisfied. \fBsvcadm refresh\fR forces dependency re-evaluation. .RE .sp .ne 2 .na \fB\fBunknown\fR\fR .ad .RS 11n \fBstat\fR(2) failed for a reason other than \fBENOENT\fR. .RE See \fBsmf\fR(5) for additional details about dependencies, grouping, and \fBrestart_on\fR values. .RE .sp .ne 2 .na \fB\fBenabled\fR\fR .ad .RS 14n 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 \fBtrue\fR or \fBfalse\fR, and the latter is designated by the presence of \fB(temporary)\fR. .sp A service might be temporarily disabled because an administrator has run \fBsvcadm disable -t\fR, used \fBsvcadm milestone\fR, or booted the system to a specific milestone. See \fBsvcadm\fR(1M) for details. .RE .RE .sp .ne 2 .na \fB-L\fR .ad .RS 20n Display the log file of the selected services and service instances, one per-line. .RE .sp .ne 2 .na \fB\fB-o\fR \fIcol\fR[,\fIcol\fR]...\fR .ad .RS 20n Prints the specified columns. Each \fIcol\fR should be a column name. See \fBCOLUMNS\fR below for available columns. .RE .sp .ne 2 .na \fB\fB-p\fR\fR .ad .RS 20n Lists processes associated with each service instance. A service instance can have no associated processes. The process ID, start time, and command name (\fBPID\fR, \fBSTIME\fR, and \fBCMD\fR fields from \fBps\fR(1)) are displayed for each process. .RE .sp .ne 2 .na \fB\fB-R\fR \fIFMRI-instance\fR\fR .ad .RS 20n Selects service instances that have the given service instance as their restarter. .RE .sp .ne 2 .na \fB\fB-s\fR \fIcol\fR\fR .ad .RS 20n Sorts output by column. \fIcol\fR should be a column name. See \fBCOLUMNS\fR below for available columns. Multiple \fB-s\fR options behave additively. .RE .sp .ne 2 .na \fB\fB-S\fR \fIcol\fR\fR .ad .RS 20n Sorts by \fIcol\fR in the opposite order as option \fB-s\fR. .RE .sp .ne 2 .na \fB\fB-v\fR\fR .ad .RS 20n Without \fB-x\fR or \fB-l\fR, displays verbose columns: \fBSTATE\fR, \fBNSTATE\fR, \fBSTIME\fR, \fBCTID\fR, and \fBFMRI\fR. .sp With \fB-x\fR, displays extra information for each explanation. .sp With \fB-l\fR, displays user-visible properties in property groups of type \fBapplication\fR and their description. .RE .sp .ne 2 .na \fB\fB-x\fR\fR .ad .RS 20n Displays explanations for service states. .sp Without arguments, the \fB-x\fR option explains the states of services which: .RS +4 .TP .ie t \(bu .el o are enabled, but are not running. .RE .RS +4 .TP .ie t \(bu .el o are preventing another enabled service from running. .RE .RE .sp .ne 2 .na \fB-z \fIzone\fR .ad .RS 20n Display only the services in the \fIzone\fR. This option is only applicable in the global zone, see \fBzones\fR(5). .RE .sp .ne 2 .na \fB-Z\fR .ad .RS 20n Display services from all zones, with an additional column indicating in which zone the service is running. This option is only applicable in the global zone, see \fBzones\fR(5). .RE .SH OPERANDS .sp .LP The following operands are supported: .sp .ne 2 .na \fB\fIFMRI\fR\fR .ad .RS 17n A fault management resource identifier (FMRI) that specifies one or more instances (see \fBsmf\fR(5)). FMRIs can be abbreviated by specifying the instance name, or the trailing portion of the service name. For example, given the FMRI: .sp .in +2 .nf svc:/network/smtp:sendmail .fi .in -2 .sp The following are valid abbreviations: .sp .in +2 .nf sendmail :sendmail smtp smtp:sendmail network/smtp .fi .in -2 .sp The following are invalid abbreviations: .sp .in +2 .nf mail network network/smt .fi .in -2 .sp If the FMRI specifies a service, then the command applies to all instances of that service, except when used with the \fB-D\fR option. .sp Abbreviated forms of FMRIs are unstable, and should not be used in scripts or other permanent tools. .RE .sp .ne 2 .na \fB\fIpattern\fR\fR .ad .RS 17n A pattern that is matched against the \fIFMRI\fRs of service instances according to the "globbing" rules described by \fBfnmatch\fR(5). If the pattern does not begin with \fBsvc:\fR, then \fBsvc:/\fR is prepended. The following is a typical example of a glob pattern: .sp .in +2 .nf qexample% svcs \e*keyserv\e* STATE STIME FMRI disabled Aug_02 svc:/network/rpc/keyserv:default .fi .in -2 .sp .RE .sp .ne 2 .na \fB\fIFMRI-instance\fR\fR .ad .RS 17n An FMRI that specifies an instance. .RE .SH COLUMNS .sp .LP Column names are case insensitive. The default output format is equivalent to "\fB-o\fR \fBstate,stime,fmri\fR". The default sorting columns are \fBSTATE\fR, \fBSTIME\fR, \fBFMRI\fR. .sp .ne 2 .na \fB\fBCTID\fR\fR .ad .RS 10n The primary contract ID for the service instance. Not all instances have valid primary contract IDs. .RE .sp .ne 2 .na \fB\fBDESC\fR\fR .ad .RS 10n A brief description of the service, from its template element. A service might not have a description available, in which case a hyphen (\fB\(hy\fR) is used to denote an empty value. .RE .sp .ne 2 .na \fB\fBFMRI\fR\fR .ad .RS 10n The \fIFMRI\fR of the service instance. .RE .sp .ne 2 .na \fB\fBINST\fR\fR .ad .RS 10n The instance name of the service instance. .RE .sp .ne 2 .na \fB\fBNSTA\fR\fR .ad .RS 10n The abbreviated next state of the service instance, as given in the \fBSTA\fR column description. A hyphen denotes that the instance is not transitioning. Same as \fBSTA\fR otherwise. .RE .sp .ne 2 .na \fB\fBNSTATE\fR\fR .ad .RS 10n The next state of the service. A hyphen is used to denote that the instance is not transitioning. Same as \fBSTATE\fR otherwise. .RE .sp .ne 2 .na \fB\fBSCOPE\fR\fR .ad .RS 10n The scope name of the service instance. .RE .sp .ne 2 .na \fB\fBSVC\fR\fR .ad .RS 10n The service name of the service instance. .RE .sp .ne 2 .na \fB\fBSTA\fR\fR .ad .RS 10n The abbreviated state of the service instance (see \fBsmf\fR(5)): .sp .ne 2 .na \fB\fBDGD\fR\fR .ad .RS 7n degraded .RE .sp .ne 2 .na \fB\fBDIS\fR\fR .ad .RS 7n disabled .RE .sp .ne 2 .na \fB\fBLRC\fR\fR .ad .RS 7n legacy \fBrc*.d\fR script-initiated instance .RE .sp .ne 2 .na \fB\fBMNT\fR\fR .ad .RS 7n maintenance .RE .sp .ne 2 .na \fB\fBOFF\fR\fR .ad .RS 7n offline .RE .sp .ne 2 .na \fB\fBON\fR\fR .ad .RS 7n online .RE .sp .ne 2 .na \fB\fBUN\fR\fR .ad .RS 7n uninitialized .RE Absent or unrecognized states are denoted by a question mark (\fB?\fR) character. An asterisk (\fB*\fR) is appended for instances in transition, unless the \fBNSTA\fR or \fBNSTATE\fR column is also being displayed. .sp See \fBsmf\fR(5) for an explanation of service states. .RE .sp .ne 2 .na \fB\fBSTATE\fR\fR .ad .RS 10n The state of the service instance. An asterisk is appended for instances in transition, unless the \fBNSTA\fR or \fBNSTATE\fR column is also being displayed. .sp See \fBsmf\fR(5) for an explanation of service states. .RE .sp .ne 2 .na \fB\fBSTIME\fR\fR .ad .RS 10n 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 (\fB_\fR) in place of blanks. .RE .SH EXAMPLES .LP \fBExample 1 \fRDisplaying the Default Output .sp .LP This example displays default output: .sp .in +2 .nf 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 13:25:03 svc:/milestone/multi-user:default \&... online 13:25:07 svc:/milestone/multi-user-server:default \&... .fi .in -2 .sp .LP \fBExample 2 \fRListing All Local Instances .sp .LP This example lists all local instances of the \fBservice1\fR service. .sp .in +2 .nf example% svcs -o state,nstate,fmri service1 STATE NSTATE FMRI online - svc:/service1:instance1 disabled - svc:/service1:instance2 .fi .in -2 .sp .LP \fBExample 3 \fRListing Verbose Information .sp .LP This example lists verbose information. .sp .in +2 .nf example% svcs -v network/rpc/rstat:udp STATE NSTATE STIME CTID FMRI online - Aug_09 - svc:/network/rpc/rstat:udp .fi .in -2 .sp .LP \fBExample 4 \fRListing Detailed Information .sp .LP This example lists detailed information about all instances of \fBsystem/service3\fR.
