How to print some aggr info in text format using API

PBRam — Fri, 03 Mar 2017 22:17:39 GMT

I am trying to print the aggregate info (size and used space) in text format . Can some one help.

Ontap: 8.3.2 p2

api = NaElement("aggr-space-get-iter")

xi = NaElement("desired-attributes")
api.child_add(xi)


xi1 = NaElement("space-information")
xi.child_add(xi1)

xi1.child_add_string("aggregate","<aggregate>")
xi1.child_add_string("aggregate-size","<aggregate-size>")
xi1.child_add_string("physical-used","<physical-used>")
xi1.child_add_string("physical-used-percent","<physical-used-percent>")

xi2 = NaElement("query")
api.child_add(xi2)


xi3 = NaElement("space-information")
xi2.child_add(xi3)

xi3.child_add_string("aggregate","aggr1*")

xo = s.invoke_elem(api)
if (xo.results_status() == "failed") :
    print ("Error:\n")
    print (xo.sprintf())
    sys.exit (1)

aggrs= xo.child_get("attributes-list").child_get("space-information").children_get()

for aggr in aggrs:
    print (aggrs.child_get("aggregate"))

Getting following error,

print (aggrs.child_get("aggregate"))
AttributeError: 'list' object has no attribute 'child_get'

You have to iterate through attributes-list

aggrs= xo.child_get("attributes-list").children_get()

for aggr in aggrs:
    print ('name {} {}'.format(aggr.child_get_string("aggregate"),aggr.child_get_string("physical-used")))

hope that help

i m getting the similar issue.tried the below suggestion.still no luck. Cna some one help me?

Traceback (most recent call last):

File "5_aggrstatuinfo.py", line 29, in <module>

aggr_list = out.child_get("attributes-list").children_get()

AttributeError: 'NoneType' object has no attribute 'children_get'

my code is:

from NaServer import *

obj = NaServer(“IPaddress”,1,150)

obj.set_server_type("FILER")

obj.set_transport_type("HTTPS")

obj.set_port("443")

obj.set_style("LOGIN")

obj.set_admin_user("admin”,”XXXXXXXX”)

api = NaElement("aggr-space-get-iter")

#xo = NaElement("desired-attributes")

#api.child_add(xo)

xi = NaElement("query")

api.child_add(xi)

xo1 = NaElement("space-information")

xi.child_add(xo1)

xo1.child_add_string("aggregate","<aggregate-Name>")

xo1.child_add_string("aggregate-size","<aggregate-size>")

xo1.child_add_string("physical-used","<physical-used>")

xo1.child_add_string("physical-used-percentage","<physical-used-percentage>")

out= obj.invoke_elem(api)

aggr_list = out.child_get("aggregates")

if (out.results_status == "failed"):

print("error\n")

print(out.sprintf())

sys.exit()

for aggrs in aggr_list.children_get():

print("a\n")

print ('name {} {}'.format(aggr.child_get_string("aggregate"),aggr.child_get_string("physical-used")))

desired-attributes and query are two different things

Here an example where you need aggregate space information without query (filter).

api = NaElement("aggr-get-iter") xi = NaElement("desired-attributes") api.child_add(xi) xo1 = NaElement("aggr-attributes") xi.child_add(xo1) xo2 = NaElement("aggr-space-attributes"); xo2.child_add_string("size-total", "<size-total>") xo1.child_add(xo2); print(xi.sprintf()) out = obj.invoke_elem(api) print(out.sprintf()) aggr_list = out.child_get("aggregates") if (out.results_status == "failed"): print("error\n") print(out.sprintf()) aggrslist = out.child_get("attributes-list") aggrs = aggrslist.children_get() for aggr in aggrs: aggrname = aggr.child_get_string("aggregate-name") aggrspaceattr = aggr.child_get("aggr-space-attributes") aggrspace = aggrspaceattr.child_get_string("size-total") print(f'{aggrname} {aggrspace}')

I just added size-total information, you can add more.

Considere to use to have the full overview.
