NAME
svcs - report service status SYNOPSIS
svcs [-aHpv?] [-o col[,col]...] [-R instance_FMRI]... [-sS col]... [FMRI | pattern] ... svcs {-d | -D} [-Hpv?] [-o col[,col]...] [-sS col]... [FMRI | pattern] ... svcs -l [FMRI | pattern] ... svcs -x [-v] [FMRI]... The svcs command displays information about service instances as recorded in the service configuration repository. The first form 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 second form prints one-line sta- tus listings for the dependencies or dependents of the service instances specified by the arguments. The third form prints detailed infor- mation 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 following options are supported: -? Displays an extended usage message, including column 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 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/. 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 FMRI is invalid. 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 con- sider the dependency to be unsatisfied. svcadm refresh forces dependency re-evaluation. unknown stat(2) failed for a reason 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 specified as either true or false, and the latter is designated by the presence of (tem- porary). A service might be temporarily disabled because an administrator has run svcadm disable -t, used "svcadm mile- stone, 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 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 instance_FMRI 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, displays verbose columns: STATE, NSTATE, STIME, CTID, and FMRI. With -x, displays extra information for each explanation. -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. The following operands are supported: instance_FMRI An FMRI that specifes an instance. FMRI An FMRI that specifes one or more instances. FMRIs can be abbreviated by specifying the instance name, or the trailing por- tion 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. COLUMNS
Column names are case insensitive. The default output format is equivalent 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: 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.
