Simple attributes of a pool?

[zlesnr]

Before I go trying to modify any part of a pool, I'd like to see what its configured as. I'm able to discover the pool easy enough.

pool = mgmt.tm.ltm.pools.pool.load(name='...', partition='...')

However, now that I have a pool object, how do I know what its attributes are?

I've discovered the to_dict() method, but the associated return has very little to do with the pool itself. Is there a simpler way to get at the attributes of a pool? I ask with the leanings of taking this to other configuration items in our F5 as well.

@zlesnr there is a .attrs property that will give you more relevant info about the resource

print(pool.attrs)

[zlesnr]

I've tried that, but I get AttributeError: '<class 'f5.bigip.tm.ltm.pool.Pool'>' object has no attribute 'attrs'. I see in github that its there, but perhaps not released yet?

f5-icontrol-rest==1.3.0
f5-sdk==2.3.3

[caphrim007]

ummm. hmm. I thought @wojtek0806 added that to a release a while ago, but maybe I'm mistaken. We're preparing a release for this week right now actually. I need to finish up trunk support then it will be released.

[wojtek0806]

Did you load the pool first? This works on collection objects or if you load resource first.

[wojtek0806]

@tar our pool module at ansible uses this btw

[zlesnr]

@wojtek0806 The code in the OP is what I'm using. The calls to pool.attrs is what produces the exception.

[wojtek0806]

looked at the source and this was moved to a different class but should be working, testing quickly in a lab now. Can you tell me what version of bigip you run this against? @zlesnr

[wojtek0806]

I have tested this with the same versions and it works for me:

from f5.bigip import ManagementRoot
mr = ManagementRoot('192.168.59.131', 'admin', 'admin')
a = mr.tm.ltm.pools.pool.load(name='test', partition='Common')

a.attrs

{u'generation': 193, u'minActiveMembers': 0, u'ipTosToServer': u'pass-through', u'loadBalancingMode': u'round-robin', u'allowNat': u'yes', u'queueDepthLimit': 0, u'membersReference': {u'isSubcollection': True, u'link': u'https://localhost/mgmt/tm/ltm/pool/~Common~test/members?ver=12.1.2'}, u'minUpMembers': 0, u'slowRampTime': 10, u'minUpMembersAction': u'failover', u'minUpMembersChecking': u'disabled', u'queueTimeLimit': 0, u'linkQosToServer': u'pass-through', u'queueOnConnectionLimit': u'disabled', u'fullPath': u'/Common/test', u'kind': u'tm:ltm:pool:poolstate', u'name': u'test', u'partition': u'Common', u'allowSnat': u'yes', u'ipTosToClient': u'pass-through', u'reselectTries': 0, u'linkQosToClient': u'pass-through', u'serviceDownAction': u'none', u'ignorePersistedWeight': u'disabled', u'selfLink': u'https://localhost/mgmt/tm/ltm/pool/~Common~test?ver=12.1.2'}

Can you check what you have in this line:

https://github.com/F5Networks/f5-common-python/blob/2.3-stable/f5/bigip/resource.py#L721

You should have the exact same code that is under that link @zlesnr

[zlesnr]

Yep, what I have on disk looks the same. Which version(s) of python is this code tested with? I'm currently using 3.6.1.

[zlesnr]

Strange.

print(pool)
print(dir(pool))

The above shows that attrs is indeed present.

[wojtek0806]

looking at tox.ini i don't think we tested this on 3.6.1, its tested on 3.5 as far as i know

[caphrim007]

3.6 in tox isnt the issue. I run 3.6 just fine with pyenv in a virtualenv.

@zlesnr how did you setup your pyenv?

[wojtek0806]

@zlesnr can you install a clean virtualenv with just the SDK and f5 rest and retest? full console output here would be useful

can you also post the contents of python_second.py ? for completeness. @zlesnr

[zlesnr]

from f5.bigip import ManagementRoot

mgmt = ManagementRoot("10.0.0.1", "admin", "password")
pool = mgmt.tm.ltm.pools.pool.load(name='apoolthatexists', partition='Common')

print(pool)
print(dir(pool))
print(pool.attrs)

[wojtek0806]

please pull latest release and retest @zlesnr

[zlesnr]

Delightful. I no longer get an exception . Thank you.

f5-icontrol-rest==1.3.0
f5-sdk==3.0.1
