CirrusGetting active pool member connections using Python
If I want to see all of the client connections connecting to a pool member from the CLI I can do something like a "show sys connection ss-server-addr 1.2.3.4". I can also do this using Postman mapping to ";, but I cannot figure out how to do this via Python.
Using Python if I try to connect to "bigip.sys.raw" I do not see a module called "connection" or anything similar. Does anyone know how, or have some sample code on how to accomplish this?
Thanks!

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)
Tim_HarberThanks 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 10.69.67.92I 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: 6I 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
is virtual server.cs-server-addrIf 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
example above (you will need to iterate the pool members) -member0_stats = members[0].stats.load()
.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"

You're saying pool member but
cs-server-addris 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'].
