Plugin/ Agent/ Host States

[Soheil Eizadi]

I am trying to understand how the Host object state transitions to Up state? I 
see it starts in Alert state.
There is not a setter for status and the comment for it in HostVO.java said:

   /**

     * Note: There is no setter for status because it has to be set in the dao 
code.

     */

    @Column(name="status", nullable=false)

    private Status status = null;


Thanks,
