SMF-Service Management facility:Service information

Lingesh
As we all know that from Solaris 10 on-wards legacy method of starting and stopping service has been replaced by SMF (Service management facility) service management. Here we are not going in depth of SMF history and theory.Here we will see how to get the list of SMF service installed in server,how to see the dependencies and dependents services,Service tree map and complete information about the services.And also we will the reason for the service fault using svcs -xv command.
Service listing and Dependencies check

Important command of SMF service listing:
table.tableizer-table { border: 1px solid #CCC; font-family: ; font-size: 12px; } .tableizer-table td { padding: 4px; margin: 3px; border: 1px solid #ccc; } .tableizer-table th { background-color: #104E8B; color: #FFF; font-weight: bold; }

SMF Service Information
svcs -a Lists all installed services
svcs -d FMRI Lists all dependencies for FMRI
svcs -d FMRI Lists all dependents for FMRI
svcs -p FMRI Show the service dependencies tree map
svcs -l FMRI Provides a complete information about FMRI
svcs -x Show reason for the service fault
svcs -xv Verbose mode debugging information


1.How to list the configured services from SMF ? 
# svcs -a 
This output will give list of legacy services,online services,disabled services and offline services.

bash-3.00# svcs -a |head
STATE          STIME    FMRI
legacy_run     May_17   lrc:/etc/rcS_d/S50sk98sol
legacy_run     May_17   lrc:/etc/rc2_d/S05vmware-tools
legacy_run     May_17   lrc:/etc/rc2_d/S10lu
legacy_run     May_17   lrc:/etc/rc2_d/S20sysetup
legacy_run     May_17   lrc:/etc/rc2_d/S40llc2
legacy_run     May_17   lrc:/etc/rc2_d/S42ncakmod
legacy_run     May_17   lrc:/etc/rc2_d/S47pppd
legacy_run     May_17   lrc:/etc/rc2_d/S70uucp
legacy_run     May_17   lrc:/etc/rc2_d/S72autoinstall
bash-3.00# svcs -a |tail
online         May_17   svc:/system/basicreg:default
online         May_17   svc:/system/zones:default
online         May_17   svc:/application/cde-printinfo:default
online         May_17   svc:/application/graphical-login/cde-login:default
online         May_17   svc:/system/vxdbd:default
online         May_17   svc:/system/xprtld:default
online         May_17   svc:/system/webconsole:console
online         May_17   svc:/application/autoreg:default
offline        May_17   svc:/application/print/ipp-listener:default
offline        May_17   svc:/application/print/rfc1179:default
bash-3.00# svcs -a |wc -l
     238
bash-3.00#


2.How to check specific service status ?

bash-3.00# svcs zones
STATE          STIME    FMRI
online         May_17   svc:/system/zones:default
bash-3.00# svcs vxdbd
STATE          STIME    FMRI
online         May_17   svc:/system/vxdbd:default
bash-3.00# svcs -a |grep zones
disabled       May_17   svc:/system/tsol-zones:default
online         May_17   svc:/system/zones:default


3.How to see complete service information and log file name ?

bash-3.00# svcs -l svc:/system/zones:default
fmri         svc:/system/zones:default
name         Zones autoboot and graceful shutdown
enabled      true
state        online
next_state   none
state_time   Fri May 17 20:08:30 2013
logfile      /var/svc/log/system-zones:default.log
restarter    svc:/system/svc/restarter:default
dependency   require_all/none svc:/milestone/multi-user-server (online)


4.To see how many services depends on particular service ?(Ex:svc:/system/zones:default) 

bash-3.00# svcs -D svc:/system/zones:default
STATE          STIME    FMRI

Here none of the system services are depends on zones services.

5.To see what are the services required to start particular service ? 

bash-3.00# svcs -d svc:/system/zones:default
STATE          STIME    FMRI
online         May_17   svc:/milestone/multi-user-server:default

i.e “Zones” service depends on “multi-user-server” service. 

6.How do you see service dependency map ?

bash-3.00# svcs -p svc:/application/graphical-login/cde-login:default
STATE          STIME    FMRI
online         May_17   svc:/application/graphical-login/cde-login:default
               May_17       3429 dtlogin
               May_17       3692 fbconsole
               May_17       3733 Xorg
               May_17       4070 dtlogin
               May_17       4145 dtgreet

7.How to check SMF services status using one command ?
The below command will report if there is an issue with SMF services.

bash-3.00# svcs -xv
svc:/application/print/server:default (LP print server)
 State: disabled since Fri May 17 20:07:30 2013
Reason: Disabled by an administrator.
   See: http://sun.com/msg/SMF-8000-05
   See: man -M /usr/share/man -s 1M lpsched
Impact: 2 dependent services are not running:
        svc:/application/print/rfc1179:default
        svc:/application/print/ipp-listener:default
