How to get the applications Assigned to a Web Acceleration Profile? (Possible API Bug)
I am trying to work out the applications a specific web acceleration profile are connected to. I am using the soap interface (ruby gem) When I make a get_application request from Soap Documentation: interfaces['LocalLB.ProfileWebAcceleration'].get_application(["/MYPARTITION/my_app_cache_profile"]) I get an empty response object: [] I would expect this to contain "/MYPARTITION/my_app.app" Verification (Profile is connected) I can confirm that this profile is connected to an app (by looking for it from the app): system_session.get_active_folder "/MYPARTITION/my_app.app" interfaces['LocalLB.ProfileWebAcceleration'].get_list ["/MYPARTITION/my_app.app/my_app_cache_profile"] NB: This does not help me as if you apply a profile to an app after creation the path is "/MYPARTITION/my_app_cache_profile" so running get_list on the app path will return 0 results even though there is a caching profile assigned.
Ruby iControl throwing non-descript soap fault on NodeAddressV2.create
So I'm receiving a soap fault when I try and create a node.

iControl EM Proxy Issues
Hi All, Trying to use the ruby f5-icontrol library to interact with Enterprise Manager's iControl proxy capability. So far I have had little luck. I have the following script, and it is functional in returning info from EM, except for when I attempt to run the get_context_id method. require 'f5-icontrol' require 'pp' wsdls = ['Management.EM'] b = F5::IControl.new('myem', 'admin', 'thepassword', wsdls).get_interfaces l = {} l['devices'] = b['Management.EM'].get_devices() l['context'] = b['Management.EM'].get_context_id() pp l This results in the following error: /usr/share/ruby/rexml/parsers/baseparser.rb:411:in `block in pull_event': Undefined prefix E found (REXML::UndefinedNamespaceException) from /usr/share/ruby/set.rb:232:in `each_key' from /usr/share/ruby/set.rb:232:in `each' from /usr/share/ruby/rexml/parsers/baseparser.rb:409:in `pull_event' from /usr/share/ruby/rexml/parsers/baseparser.rb:183:in `pull' from /usr/share/ruby/rexml/parsers/streamparser.rb:16:in `parse' from /usr/share/ruby/rexml/document.rb:243:in `parse_stream' from /usr/local/share/gems/gems/soap2r-1.5.8/lib/xsd/xmlparser/rexmlparser.rb:27:in `do_parse' from /usr/local/share/gems/gems/soap2r-1.5.8/lib/soap/parser.rb:102:in `parse' from /usr/local/share/gems/gems/soap2r-1.5.8/lib/soap/processor.rb:39:in `unmarshal' from /usr/local/share/gems/gems/soap2r-1.5.8/lib/soap/rpc/proxy.rb:291:in `unmarshal' from /usr/local/share/gems/gems/soap2r-1.5.8/lib/soap/rpc/proxy.rb:190:in `route' from /usr/local/share/gems/gems/soap2r-1.5.8/lib/soap/rpc/proxy.rb:149:in `call' from /usr/local/share/gems/gems/soap2r-1.5.8/lib/soap/rpc/driver.rb:151:in `call' from (eval):6:in `get_context_id' from em2.rb:11:in `' I'm running ruby 2.0.0p247, EM 3.1.1 (40.7), and have tried f5-icontrol gems for v11.3.0 and v11.4.1. Any ideas? Thanks.
API Convetion confusions
Consider the following. ltm = F5::IControl.new(ltm_name, username, password, ["LocalLB.VirtualServer"]).get_interfaces["LocalLB.VirtualServer"] ltm.add_rule(["temp_vserver"], [[{:rule_name => "new_rule, :priority => 3}]]) The irule object/hash is imbedded in two arrays. The API is shown here. in LocalLB__VirtualServer__VirtualServerRule [] [] rules In referncing the API documentation how am I to know that the irule object should be imbedded in two arrays? It makes sense to me that the irule object is in a hash corresponding with the struct defined in the API. {:rule_name => "new_rule", :priority => 3} It also makes sense to me that this object is inside of an array, since you may want to add multiple rules at the same time. [{:rule_name => "new_rule", :priority => 3}, {:rule_name => "other_new_rule", :priority => 4}] What I don't get is why all of this is embedded in yet another array and I also don't see how I am supposed to tell this from the API. I figured this out by reading others code on the devcentral codeshare.F5 LTM SOAP API - Ruby f5-icontrol Gem - Could not find element by name: pool_names
Hi there, Very much hoping there is someone that can help me with this problem. I am trying to gather some information about pool members from the F5 API (still on SOAP for a little while more). I am using the f5-icontrol Gem described here: http://www.rubydoc.info/gems/f5-icontrol/0.1.5 Specifically, I am trying to call the LocalLB.Pool.get_all_member_statistics method passing in a string of the pool name and receive the following error: /full/path/ruby-2.1.6/gems/savon-2.11.1/lib/savon/response.rb:85:in `raise_soap_and_http_errors!': (SOAP-ENV:Server) **Could not find element by name: pool_names** (Savon::SOAPFault) I am able to run a number of other methods and get back data, for example I can run api.LocalLB.Pool.get_list & api.Management.UserManagement.get_my_permission() and data is returned immediately. Also, the string I am passing in to get_all_member_statistics is the exact string returned by api.LocalLB.Pool.get_list. Note that I tried running as a normal user as well as an F5 admin. Here is my exact code: require 'f5-icontrol' F5::Icontrol.configure do |f| f.host = "big-ip-url.domain.com" f.username = "user" f.password = "pass" end api = F5::Icontrol::API.new get_list runs perfectly and returns all of the pool names in the format of "/Common/full_pool_name" for example response = api.LocalLB.Pool.get_list This successfully returns the permissions for the current user response = api.Management.UserManagement.get_my_permission() This is NOT working and returns the error above response = api.LocalLB.Pool.get_all_member_statistics("Common/full_pool_name_exactly_as_it_appears_in_the_UI") puts response.inspectf5-icontrol-10.2.0.2 gem causing various warnings with ruby 1.9.3
