NAME
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 | pattern]... svcs -x [-v] [FMRI]...
DESCRIPTION
The svcs command displays information about service instances as recorded in the service configuration reposi- tory. The first form of this command prints one-line status listings for service instances specified by the argu- ments. Each instance is listed only once. With no arguments, all enabled service instances, even if temporar- ily 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, prob- lematic 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 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 ser- vice instances, with one service attribute displayed for each line. Information for dif- ferent 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 addi- tion 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 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 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 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 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 col- umns. 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.
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 typical 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 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 descrip- tion 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(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 13:25:03 svc:/milestone/multi-user: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 system/service3. Additional fields can be dis- played, 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 service 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.
