NetApp API using call quota list

[haha]

Can not have more than 1000 quota list calls using NetApp API?

I'm not terribly familiar with the Java side of things, but do you know which ZAPI it's using?  If it's using "quota-list-entries" then I think it does have some maximum...it's a single API call that will return all results, up to the maximum, at once.  Using the iteration set of APIs should have no maximum however.  You'll need to use quota-list-entries-iter-start followed by quota-list-entries-iter-next until it returns that there are no futher entries and, to be polite, end with quota-list-entries-iter-end.

Hope that helps.

Hi Andrew,

Even I am facing the same issue.

Could you please help me with the syntax for using "quota-list-entries-iter-start", "quota-list-entries-iter-next" and "quota-list-entries-iter-end".

Thanks in advance

Hello,

Yes you can get more then a thousand quotas returned by API but not in a single API call. You should use the next-tag to keep calling for the next until there are none.

I am not a Java guy so I'll give you a sample of my Python code where I get a lot of quotas from quota report. In one filer it returns more than 60k quotas, so it works.

def _get_quota_report_cluster(filer):
    quota_report = []

    # simulate a do while
    tag = None
    while True:
        if tag:
            api = filer.call_api('quota-report-iter', ('max-records', '200'), ('tag', tag))
        else:
            api = filer.call_api('quota-report-iter', ('max-records', '200'))
        # check if filer connection have any error
        if api == "error":
            return []
        tag = api.child_get_string('next-tag')

        attribute_list = api.child_get('attributes-list')

        if attribute_list and attribute_list.has_children():
            for q in attribute_list.children_get():
                quota = Quota()
                quota.filer_name = q.child_get_string('vserver')
                quota.volume = q.child_get_string('volume')
                quota.tree = q.child_get_string('tree')
                quota.target = q.child_get_string('quota-target')
                quota.type = q.child_get_string('quota-type')

                if quota.type == 'user' or quota.type == 'sid':
                    if q.child_get('quota-users') is None:
                        continue
                    for user in q.child_get('quota-users').children_get():
                        quota.user = user.child_get_string('quota-user-name')
                try:
                    quota.disk_used_gb = q.child_get_int('disk-used')
                    quota.disk_limit_gb = q.child_get_int('disk-limit')
                except ValueError:
                    quota.disk_used_gb = 0
                    quota.disk_limit_gb = 0
                quota_report.append(quota)
        if not tag:
            return quota_report

Pay attention that Filer and Quota are classes that I created, so it's not in the NMSDK. The main point here is the concept.

In this example the function returns a list of quotas object.
