Manage all process khaganat
|
||||
Launch this prorgam in background and use clientManager to manipulate process
|
||||
|
||||
you can launch command :
|
||||
[POST] SHUTDOWN : Stop all process and stop manager
|
||||
[POST] STARTALL : Start all process
|
||||
[GET] STATUSALL : Get status all process
|
||||
[POST] STOPALL : Stop all process
|
||||
[POST] START {'name': program} : Start one program
|
||||
[POST] ACTION {'name': program, 'action' : action} : Send action one program (send to input program)
|
||||
[GET] STATUS {'name': program} : Get status one program
|
||||
[POST] STOP {'name': program} : Stop one program
|
||||
[GET] LOG {'name': program, 'first-line': firstline } : Get log for one program
|
||||
Design
|
||||
+ Manager
|
||||
+ -> ManageCommand [NumCommand]
|
||||
| + -> read_output (thread)
|
||||
+ -> ServerHttp -> khaganatHTTPServer
|
||||
| + -> ManageHttpRequest (each request are send on this class) [NumRequestHttp]
|
||||
|
||||
http(s) command :
|
||||
[Method] /Path {json data}
|
||||
--------------------------
|
||||
[POST] /SHUTDOWN : Stop all process and stop manager
|
||||
[POST] /STARTALL : Start all process
|
||||
[GET] /STATUSALL : Get status all process
|
||||
[POST] /STOPALL : Stop all process
|
||||
[POST] /START {'name': program} : Start one program
|
||||
[POST] /ACTION {'name': program, 'action' : action} : Send action one program (send to input program)
|
||||
[GET] /STATUS {'name': program} : Get status one program
|
||||
[POST] /STOP {'name': program} : Stop one program
|

[GET] /LOG {'name': program, 'first-line': firstline } : Get log for one program
