The stats are pulled from the pool or member itself. Try this for an example:

!/usr/bin/env python3

from f5.bigip import ManagementRoot
from getpass import getpass
from pprint import pprint

hostname = 'my.f5.ltm.net'
username = 'foo'

mgmt = ManagmentRoot(hostname, username, getpass())

pool = mgmt.tm.ltm.pools.pool.load(name='my_pool_name')
poolstats = pool.stats.load()

pprint(poolstats.raw)

members = pool.members_s.get_collection()
member0_stats = members[0].stats.load()

pprint(member0_stats.raw)

    Thanks Jason. I am able to get stats the way you describe, but what I am trying to get is the actual connected clients connected to each pool member. For example from the CLI if I do a

     show sys connection cs-server-addr 10.69.67.92

    I get the following resuts:'

    Sys::Connections
192.168.181.163:51952  10.69.67.92:443  10.69.67.15:4822  10.69.65.65:44301  tcp  3  (tmm: 10)  none
192.168.181.160:62556  10.69.67.92:443  10.69.67.15:21454  10.69.65.64:44301  tcp  2  (tmm: 10)  none
10.74.10.114:60012  10.69.67.92:443  10.69.67.15:4246  10.69.65.65:44301  tcp  11  (tmm: 11)  none
192.168.181.162:57199  10.69.67.92:443  10.69.67.15:32841  10.69.65.63:44301  tcp  2  (tmm: 6)  none
192.168.181.156:58295  10.69.67.92:443  10.69.67.15:57537  10.69.65.64:44301  tcp  1  (tmm: 1)  none
10.69.53.175:52661  10.69.67.92:443  10.69.67.15:57967  10.69.65.63:44301  tcp  10  (tmm: 7)  none
Total records returned: 6

    I am trying to get this same data using the API. I can get it via REST using Postman, but cannot figure out how to do it using Python.

    You're saying pool member but 

    cs-server-addr

    is virtual server. 

    If you want connections to the virtual server use:

    virtual = mgmt.tm.ltm.pools.pool.load(name='my_vs_name')
vsstats = virtual.stats.load()

    If you want pool member stats they are in the 

    member0_stats = members[0].stats.load()

    example above (you will need to iterate the pool members) - 

    member0_stats.entries['serverside.curConns']

    . 

    Here's a graphical breakdown of the various cs/ss arguments:

    That example was a virtual IP, but was just the example IP I had in front on me. In reality I need this for both virtual servers and pool members.

     

    But in any case, when I use your example for pool members I get the output of the value of the number of connected clients instead of the list of client IP's connected to the pool member as I showed above. My results for that code give me:

     

    {'value': 5}

    What I need is the list of those 5 IP's that are currently connected to that pool member which I can get using the CLI command "show sys connection ss-server-addr x.x.x.x"

    Ahhh... Okay, sorry, I'm picking up what you're putting down now.

     

    I don't think that the Python SDK supports this but you can do it with REST calls (using 

    requests
    or your preference).

     

    Here are a couple pages describing this:

     

    https://devcentral.f5.com/s/articles/connection-list-via-icontrolrest-api

     

    https://devcentral.f5.com/s/articles/demystifying-icontrol-rest-part-3-how-to-pass-query-parameters-and-tmsh-optionss (example 4 is exactly what you're trying to do, I think)

     

    I suggest opening an RFE on the GitHub page:
