cdb.get_object not working

ajbharad · ‎05-07-2019

get_object via Maapi API is working as expected where as via CDB API it`s not.
Can anybody tell me what wrong am I doing here ?

(NCS Version : nso-4.7.2.1)

>>> val = maapi.get_object(sock_maapi, th, 500, "/org-openroadm-alarm:active-alarm-list/activeAlarms{SM/HW_ENVMON_PEM_ALARM/22#CHASSIS/LCC/1}")
>>> val = cdb.get_object(cdb_socket, 1, "/org-openroadm-alarm:active-alarm-list/activeAlarms{SM/HW_ENVMON_PEM_ALARM/22#CHASSIS/LCC/1}")

get_object returns *all* the children for a given list instance. But only *N* children are filled with the correct values. The rest of them are dummy values, with 'UNKNOWN_TYPE' and 'badval'.

In your maapi call above, you ask for 500 values under that list instance. In the CDB call, you ask only for 1 value, so you get a proper value only for the first leaf in the list, which it the key. Increase that param in the CDB call, and you can get the same output as your maapi call above.
