```plantuml

interface Task {

    name: String

    description: String

    command: C

    precondition: P

}

interface Scheduler {

    tasks: Collection>    

    plan(task: Task): Optional> 

    pause(task: Task): Optional> 

    remove(task: Task): Optional>

    task: Task

    journals: List 

    cancel(force: Boolean): void

}

interface Journal {

    timestamp: long

}

```

## Dry run a task

```plantuml

actor User as U

participant Task as T

participant DryRun as D

participant Execution as E

create T

U -> T: define

U -> D: execute(task)

create E

D -> E: new

```

## Plan a task

```plantuml

actor User as U

participant Scheduler as S

participant Execution as E

participant Timer as M

U -> S: plan(task)

create E

S -> E: new

create M

S -> M: schedule(task)

M -> E: on(timeout)

E -> E: run

E -> S: finish(execution)

```

## Alarm a failure of execution

```plantuml

participant Execution as E

participant Scheduler as S

participant Alarm as A

actor User as U

E -> S: finish(failure)

S -> A: trigger(report, user)

A -> U: notify(report)

```

## Detect the reason of alarm

```plantuml

actor User as U

participant Scheduler as S

participant Execution as E

U -> S: latest(task)

U -> E: journals

```
