SMF - Service Management Facility

Expose smf(5) to Node.js for Solaris/Illumos based operating systems

Install

Install locally to use as a module

npm install smf

Install globally to use the command-line tool smf

npm install -g smf

Usage

as a module

var smf = require('smf');

as a command-line tool

~$ smf [ service-name ]

Functions

smf.svcs(callback(err, services))

Call smf.svcs with a single callback argument to get a list of service fmri's and states on the system.

smf.svcs('name', callback(err, svc))

Call smf.svcs with a service name and a callback to get information about the given service.


smf.svcadm('action', 'name')

Do a given action to the given name. For example smf.svcadm('disable', 'apache');. This command will return immediately, without waiting for the service to be disabled fully, and without checking error codes.

smf.svcadm('action', 'name', {option:value}, callback(err, code))

Do a given action to the given name with additional options. When the command is finished the callback will be called with an error message (or null) as the first argument, and the exit code of the svcadm(1M) call.

Options

  1. {temporary:true} - Temporarily disable or enable a service
  2. {wait:true} - Wait for the service to change state before executing callback

Options and callbacks are optional. See EXAMPLES for more information.

Example

smf.svcs()

get a list of all services and their states

var svcs = require('smf').svcs;
svcs(function(err, services) {
  // services => list of all service fmri's on the system
});

yields

[ { state: 'legacy_run', fmri: 'lrc:/etc/rc2_d/S98deallocate' },
  { state: 'legacy_run', fmri: 'lrc:/etc/rc2_d/S89PRESERVE' },
  { state: 'legacy_run', fmri: 'lrc:/etc/rc2_d/S72autoinstall' },
  { state: 'legacy_run', fmri: 'lrc:/etc/rc2_d/S20sysetup' },
  { state: 'disabled', fmri: 'svc:/pkgsrc/denyhosts:default' },
  { state: 'online',
    fmri: 'svc:/application/splunk:default' },
  { state: 'disabled', fmri: 'svc:/network/denyhosts:default' },
  { state: 'disabled',
    fmri: 'svc:/application/testing/nginx:default' },
...
]

get information about a specific service

svcs('boot-archive', function(err, svc) {
  // svc => associative array of service information
});

yields

{ fmri: 'svc:/system/boot-archive:default',
  name: 'check boot archive content',
  enabled: true,
  state: 'online',
  next_state: 'none',
  state_time: 'Wed Apr 25 01:32:33 2012',
  logfile: '/var/svc/log/system-boot-archive:default.log',
  restarter: 'svc:/system/svc/restarter:default',
  dependency: [ 'require_all/none svc:/system/filesystem/root (online)' ] }

smf.svcadm()

var svcadm = require('smf').svcadm;

// disable nginx without wating or confirmation
svcadm('disable', 'nginx');

// enable nginx and callback with results
svcadm('enable', 'nginx', function(err, code) {
  if (err) throw err;
  console.log('Return code %d', code);
});

// disable nginx, wait for it to enter 'disabled' state, and callback
svcadm('disable', 'nginx', {wait:true}, function(err, code) {
  if (err) throw err;
  console.log('Return code %d', code);
});

// restart nginx without waiting or confirmation
svcadm('restart', 'nginx');

// temporarily disable nginx without waiting or confirmation
svcadm('disable', 'nginx', {temporary:true});

Command Line

If you install this module globally you will also get the smf tool to expose information from svcs(1). Run it without any arguments to get a newline separated list of service fmri's on the system. Run it with a service-name argument to get a json object of information about the given service.

Inspired by the smf bash script by @dshaw.

Example

Get a list of fmri's on the system

root@dave.voxer.com# smf | tail -3
svc:/milestone/devices:default
svc:/system/device/local:default
svc:/system/boot-archive:default

Get information about the nginx service

root@dave.voxer.com# smf nginx | json
{
  "fmri": "svc:/network/nginx:default",
  "name": "Nginx 1.0.12",
  "enabled": true,
  "state": "online",
  "next_state": "none",
  "state_time": "May  4, 2012 07:45:13 PM PDT",
  "logfile": "/var/svc/log/network-nginx:default.log",
  "restarter": "svc:/system/svc/restarter:default",
  "contract_id": 68,
  "dependency": [
    "require_all/none svc:/system/filesystem/local (online)",
    "require_all/none svc:/network/loopback (online)"
  ],
  "process": [
    {
      "pid": 568,
      "cmd": "/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf"
    },
    {
      "pid": 569,
      "cmd": "/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf"
    }
  ]
}

Get the logs from a service (easier than tail -20 "$(svcs -L <service>)")

root@dave.voxer.com# smf tail name-services
/var/svc/log/milestone-name-services:default.log
[ Apr 25 01:32:33 Enabled. ]
[ Apr 25 01:32:35 Executing start method (null). ]

root@dave.voxer.com# smf -L name-services
/var/svc/log/milestone-name-services:default.log
