Run

First take a look to sysdweb.conf file to configure sysdweb. Is self explanatory.

You can place sysdweb.conf in /etc for system, in user home ~/.config/sysdweb/sysdweb.conf or in same directory where you run sysdweb.

Once you have configured sysdweb, simply run.

sysdweb

By default sysdweb listen in 10088 port to 127.0.0.1, you can change listen port and address with -p and -l or via environment variables.

sysdweb -p 9080 -l 0.0.0.0

Current config environment variables are the following.

Variable	Description
SYSDWEB_CONFIG	Config file location
SYSDWEB_HOST	Listen address
SYSDWEB_PORT	Listen port
SYSDWEB_LOGLEVEL	Log level, effective values are WARNING, INFO and DEBUG

API

You can control configured services via REST API, for example, with curl.

The API endpoint is /api/v1/<service>/<action>, always GET and response a json with following format.

{
  "<action>": "<result>"
}

The <service> tag is defined in config file and match with section label. For example, in following config, the service would be ngx.

[ngx]
title = Nginx
unit = nginx.service

The posible <actions> are.

• start
• stop
• restart
• reload
• reloadorrestart
• status
• journal

All actions (except status and journal) return as result OK if can communicate with DBUS or Fail if any error occurs.

For status action, the posible responses are.

• active (started unit)
• reloading
• inactive (stopped unit)
• failed (stopped unit)
• activating
• deactivating
• not-found (for inexistent unit)

By default /api/v1/<service>/journal returns 100 tail lines of journal file of <service> unit. You can specify the number of lines by this way.

/api/v1/<service>/journal/200

In the example defined above all valid endpoints are.
