    This is tested with Python 3.4.3 and BigIP 12.1. Did not have 12.0 installation readily available, but it should work the same for you

    from f5.bigip import ManagementRoot

 Optional: omit unsecure certificate warnings from output
import requests
from requests.packages.urllib3.exceptions import InsecureRequestWarning
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)

API_ROOT = ManagementRoot("bip-01", "admin", "admin")
VSERVER_COLLECTION = API_ROOT.tm.ltm.virtuals.get_collection()

for vserver in VSERVER_COLLECTION:
    print(vserver.name)
     Catch an error to avoid a VS with no iRules breaking the script prematurely
    try:
        irules = vserver.rules
    except AttributeError:
        print('- No iRules on this Virtual Server!')
    else:
        for rule in vserver.rules:
            print('-', rule)

    Output in test env:

    $ python list_irules.py

vs_0.0.0.0_any
- No iRules on this Virtual Server!
vs_test_80
- /Common/ir_do_nothing
- /Common/ir_do_nothing_again
vs_test_443
- /Common/ir_do_nothing
- /Common/ir_do_nothing_again

    As you can see from the script above, this takes a bit of testing to get the iRules listed. Ofcourse, ideally either the API or SDK should return an empty list if there are no iRules on a Virtual Server, rather than a script-breaking "AttributeError: 'f5.bigip.tm.ltm.virtual.Virtual'>' object has no attribute 'rules'". SDK is a build up on top of a problematic API, so eventually this problem should be addressed by the API developers.

@jaykumar_f5 i tried this. It seems to give input but not the exact output like

 

vip1 - irule1 irule2

 

vip2 irule1 irule2

 

my exact requirements is to know how many vip's have one particular vip attached {code}

 

!/usr/bin/python

from import BigIP import requests from requests.packages.urllib3.exceptions import InsecureRequestWarning requests.packages.urllib3.disable_warnings(InsecureRequestWarning)

 

Connect to the BigIP

bigip = BigIP("hostname", "username", "password")

 

Get a list of all pools on the BigIP and print their name and their members' name

for virtual in bigip.ltm.virtuals.get_collection(): virt = bigip.ltm.virtuals.virtual.load(partition=virtual.partition, name=virtual.name) rule=virt.rules for rule in rules: print "Partition: %s Virtual: %s rule: %s" % (virtual.partition, virtual.name, rule.name) {code}

Hi

 

You mentioned "my exact requirements is to know how many vip's have one particular vip attached {code}"

 

Do you mean you need to know how many vip's are using a particular iRule? If so you can add a for loop with the code provided earlier to accomplish this

 

from f5.bigip import ManagementRoot

 Optional: omit unsecure certificate warnings from output
import requests
from requests.packages.urllib3.exceptions import InsecureRequestWarning
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)

API_ROOT = ManagementRoot("bip-01", "admin", "admin")
VSERVER_COLLECTION = API_ROOT.tm.ltm.virtuals.get_collection()
IRULE_COLLECTION = API_ROOT.tm.ltm.rules.get_collection()

for rule in IRULE_COLLECTION:
    count = 0
    print('iRule Evaluated: ', rule.name)
    for vserver in VSERVER_COLLECTION:
        print(vserver.name)
         Catch an error to avoid a VS with no iRules breaking the script prematurely
        try:
            irules = vserver.rules
        except AttributeError:
            print('- No iRules on this Virtual Server!')
        else:
            for vs_rule in vserver.rules:
                if vs_rule == rule.fullPath:
                    print('  ', virtual.name)
                    count += 1
    print('iRule: ', rule.name)
    print('Used: ', count)

Output should look similar to this

 

iRule Evaluated: _sys_https_redirect
    app1_vs virtual server using the irule
    app2_vs virtual server using the irule
iRule:  _sys_https_redirect iRule with count 
Used:  2

Hope this helps
