Polling for a specific event ucsmsdk.

Optional poll mode is added to wait_for_event API

The below code will wait for the usr_lbl property of the service profile org-root/ls-demo-sp to change to demo_label. It will poll the server every poll_sec=10 here. It will timeout after 600 seconds.

wait_for_event will keep the script alive until (i) either the condition is met or (ii) timeout is triggered

from ucsmsdk.ucshandle import UcsHandle

def usr_label_changed(mce):  
     print(mce.mo.usr_label)
     handle.logout()

handle = UcsHandle("192.168.1.1", "username", "password")  
handle.login()

sp_mo = handle.query_dn("org-root/ls-demo-sp")

handle.wait_for_event(  
    mo=sp_mo,
    prop="usr_lbl",
    value="demo_label",
    cb=usr_label_changed,
    timeout=600,
    poll_sec=10
    )
