List of F5 iControl REST API Endpoints
As I could not find a complete API Reference for the F5 iControl REST API, I created a list myself. This list is not (yet) complete. I created it with the help of an API crawler and added manually some endpoints extracted from the F5 documentation. It would be great if this list gets more complete by time. Feel free to fork this repository and create a pull requests for additions and corrections. Any help and feedback is very welcome! At the moment it is a simple plain text file. My future plans are: Complete the list of endpoints Publish an OpenAPI 3 file You can find the list in my public GitHub repository. Happy RESTing!
Python module to post and retrieve IControl Rest JSON objects for AVR statistics
Problem this snippet solves: This module simplifies making Python dictionary objects that are converted to IControl rest AVR JSON objects. It also handles making AVR requests and retrieving results as well allowing multiple AVR requests to be queued, posted and retrieved. It also has some basis type checking for the elements of a AVR request. This module requires Bigip 12.1 on the target that statistics are retrieved. How to use this snippet: The main class is rest_avr.avr_req. It is a dictionary class that maps directly to an IControl Rest AVR JSON request as translated by json.dumps. Each dictionary element is an object derived from a customer class for each part of the request. The element classes have add() and clear() functions. if the element class only allows one entry the add() function will replace the existing entry, otherwise it will append the entry to the request element. The rest_avr.avr_req class also has functions to populate the HTTP host and authentication values for the target system. rest_avr.avr_req.post_and_response returns the Python representation of the JSON result of the query. rest_avr.avr_req.add_to_queue() adds the currently constructed request to a queue of requests to post. rest_avr.avr_req.post_and_response_queue() returns a python list of results of queued queries. The following code sample constructs, posts and returns results for an AVR statistics request for specific DNS records and a specificrecord type, then queues multiple quests and posts and returns results. #!/usr/bin/python import json import sys import time import rest_avr #print rest_avr.ShowAVRJsonApi #Populate the url avr_dns_req=rest_avr.avr_req() avr_dns_req.auth('admin','admin') avr_dns_req.url_base('10.10.2.113','dns') #Populate the json object avr_dns_req['analyticsModule'].add('dns') avr_dns_req['reportFeatures'].add('time-aggregated') avr_dns_req['entityFilters'].add('domain-name', 'OPERATOR_TYPE_EQUAL', ['test2.test1.com','test1.test1.com']) avr_dns_req['entityFilters'].add('query-type', 'OPERATOR_TYPE_EQUAL', ['a']) avr_dns_req['viewMetrics'].add('packets') avr_dns_req['viewDimensions'].add('domain-name') avr_dns_req['metricFilters'].add('packets', 'OPERATOR_TYPE_GREATER_THAN', 0) avr_dns_req['sortByMetrics'].add('packets', 'ascending') avr_dns_req['pagination'].add(20, 0) avr_dns_req['timeRange'].add(1461778251000000, None) #Post and retrieve results. result_py=avr_dns_req.post_and_response() if result_py != None: print ('\n' + result_py['results']['timeAggregated'][0]['dimensions'][0]['value'] + " " + result_py['results']['timeAggregated'][0]['metricValues'][0]['value'] + '\n') else: print result_py.error_layer print result_py.error_code print result_py.error_text # Now add multiple requests to a queue avr_dns_req.add_to_queue() avr_dns_req['entityFilters'].clear() avr_dns_req['entityFilters'].add('query-type', 'OPERATOR_TYPE_EQUAL', ['aaaa']) avr_dns_req.add_to_queue() #post and retrieve queued results result_py_q=avr_dns_req.post_and_response_queue() for result_py in result_py_q: if result_py != None: print ('\n' + result_py['results']['timeAggregated'][0]['dimensions'][0]['value'] + " " + result_py['results']['timeAggregated'][0]['metricValues'][0]['value'] + '\n') else: print result_py.error_layer print result_py.error_code print result_py.error_text Code : """ rest_avr provides a python interface to Bigip AVR statistics using the REST API.

Problem this snippet solves: Overview This is a script which will generate a report of the BIG-IP LTM configuration on all your load balancers making it easy to find information and get a comprehensive overview of virtual servers and pools connected to them. This information is used to relay information to NOC and developers to give them insight in where things are located and to be able to plan patching and deploys. I also use it myself as a quick way get information or gather data used as a foundation for RFC's, ie get a list of all external virtual servers without compression profiles. The script has been running on 13 pairs of load balancers, indexing over 1200 virtual servers for several years now and the report is widely used across the company and by many companies and governments across the world.

I was working on an iRule that only needed an OR if I didn’t reverse the logic on of them. But when I looked at the original problem, it needed one condition or the other but not both. You can nest conditionals to accomplish this, but I wanted an XOR operator, and Tcl doesn't have one at the string level, only with bitwise operations. So here is what that looks like in a truth table, where A could be an IP address range, B could be a hostname, and Q would be the truth condition. A B Q 0 0 0 0 1 1 1 0 1 1 1 0 In an iRule, this would look like this structurally (but you would need to add your comparisons for each A/B variable to whatever makes them true: if { ($a || $b) && !($a && $b) } { # act on the XOR true condition } else { # act on the XOR false condition }Knowledge sharing: Velos and rSeries (F5OS) basic troubleshooting, logs and commands
This another part of my Knowledge sharing articles, where I will take a deeper look into Velos and rSeries investigation of issues, logs and command. 1. Velos HA controller and blade issues. As the Velos system is the one with two controllers in active/standby mode only with Velos it could be needed to check if there is an issue with the controller's HA. As the controller's HA order can be different for the system and the different partitions to check the HA for the system use the /var/log_controller/cc-confd file or for a partition HA issue look at the partition velos log at /var/F5/partition<ID>/log/velos.log . Also you can enable HA debug for the controllers with " system dbvars config debug confd ha-state-machine true ". Overview of HA: https://support.f5.com/csp/article/K19204400 Controller HA: https://support.f5.com/csp/article/K21130014 Partition HA: https://support.f5.com/csp/article/K58515297 List of Velos/rSeries services: Overview of F5 VELOS chassis controller services Overview of F5 VELOS partition services Overview of F5 rSeries system services 2. Entering into F5OS objects. The rSeries and Velos tenants are like vCMP quests with VIPRION and sometimes if there are access issues with them it could be needed to open their console. For this the "virtctl" command can be used and as an example " /usr/share/omd/kubevirt/virtctl console<tenant_name>-<tenant_instance_ID> ". Also as velos uses blades and partitions it could be needed to ssh to a blade with " ssh slot<number> " or to enter a partition with " docker exec -it partition<ID>_cli su admin " as sometimes for example to see the GUI logs entering the GUI container for the partition could be needed but F5 support will for this in most cases and maybe this will be the way to enter the BIG-IP NEXT CLI. Overview of VELOS system architecture: https://support.f5.com/csp/article/K73364432 Overview of rSeries system architecture: https://support.f5.com/csp/article/K49918625 rSeries tanant access: https://support.f5.com/csp/article/K33373310 Velos blade and tenant access: https://support.f5.com/csp/article/K65442484 Velos partition access: https://support.f5.com/csp/article/K11206563 3. Usefull commands and logs. For Velos/rSeries as this is a system with a cluster the "show cluster" command is usefull to see any issues (look fo "cluster is NOT ready."). Also the velos.log for the controller and partitions is a great place to start and debug level can be enabled for it under " SYSTEM SETTINGS Log Settings " as this is also the place for rSeries logging to be set to debug. Also the /var/log/openshift.log is good be checked with velos if there are cluster issues or or ks3.log in rSeries. Also the confd logs are like mcpd logs, so they are really usefull for Velos or rSeries. Other nice commands are docker ps, oc get pod --all-namespaces -o wide, kubectl get pod --all-namespaces -o wide but the support will ask for them in most cases.

Velos and rSeries tcpdumps packet captures, file utility and qkview files. For Velos qkviews ca be created for controller or partition as they are seperate qkviews. Tcpdumps for client traffic are done a tcpdump utility from the F5OS (su - admin) and a tcpdump in the Linux kernel is just for the managment ip addresses of the appliance , controller (floating or local) , partition or tenant. The file utility allows for file transfers to remote servers or even downloading any log from the Velos/rSeries to your computer as this was not possible before with iSeries or Viprion. Also the file utility starts outbound session to the remote servers so this an extra security as no inbound sessions need to be allowed on the firewall/web proxy and it can be even triggered by API call and I may make a codeshare article for this. Velos tcpdump utility: https://support.f5.com/csp/article/K12313135 rSeries tcpdump utility: https://support.f5.com/csp/article/K80685750 Qkview Velos: https://support.f5.com/csp/article/K02521182 Qkview Velos CLI location: https://support.f5.com/csp/article/K79603072 Qkview rSeries: https://support.f5.com/csp/article/K04756153 SCP: https://support.f5.com/csp/article/K34776373 For rSeries 2000/4000 tcpdump is different as SR-IOV not FPGA (rSeries Networking (f5.com)) is used to attach interfaces directly to the tenant VM: Article Detail (f5.com) 5. A final fast check could be to use ''kubectl get pods -o wide--all-namespaces'' (with Velos also ''oc get pods -o wide --all-namespaces'' should also work) to see that all pods are ok and running. Also ''docker ps'' or '' docker ps --format 'table {{.Names}}\t{{.RunningFor}}\t{{.Status}}' '' are usefull to see a container that could be going down and up and this can be correlated with issues seen with "show cluster" command. 6. The new F5OS has much better hardware diagnostics than the old devices, so no more the need to do EUD tests as all system hardware components and their health can be viewed from the GUI or CLI and also this is shown in F5 ihealth! https://techdocs.f5.com/en-us/velos-1-5-0/velos-systems-administration-configuration/title-system-settings.html 7. For Velos and rSeries always keep the software up to date as for example I will give with the Velos 1.5.1 the cluster rebuild because of the openshift ssl cert being 1 year is much simpler or the F5 rSeries and the Cisco Nexus issues or the corrupt Qkview generation when the GUI not the CLI is used (the velos cluster rebuild with touch /var/omd/CLUSTER_REINSTALL can solve many issues but it will cause some timeout): http://cdn.f5.com/product/bugtracker/ID1135853.html https://my.f5.com/manage/s/article/K000092905 https://support.f5.com/csp/article/K79603072 In the future ''docker'' commands could be not available but then just use "crictl" as this replaces the docker init system for kubernetes.
GTM return LDNS IP to client
Problem this snippet solves: We do a lot of our load balancing based on topology rules, so it's often very useful to know where the DNS request is actually coming from rather than just the client's IP and the DNS servers they have configured. Especially if they're behind an ADSL router doing NAT or some other similar set up. This rule simply returns the IP address of the LDNS that eventually made the query to the GTM device in the response to a lookup for the WideIP using the rule, as well as logging the response and perceived location. Code : rule "DNS_debug" partition "Common" { when DNS_REQUEST { host [IP::client_addr] log local0.err "Debug address : [IP::client_addr] [whereis [IP::client_addr]]" } }
PowerShell module for the F5 LTM REST API
Problem this snippet solves: To report an issue with the F5-LTM or F5-BIGIP modules, please use the Issues sections of the GitHub repos (here and here) instead of commenting here. Thanks! This PowerShell module uses the iControlREST API to manipulate and query pools, pool members, virtual servers, and iRules. It aims to support version 11.5.1 and higher, and to conform to the schedule for technical support of versions, though this may eventually prove to become difficult. The module currently includes some functionality that, strictly speaking, is outside the scope of the LTM module. Hence, there is an active effort to wrap this LTM module into a larger BIG-IP module, and relocate that functionality elsewhere within that parent module, as well as expand the scope of functionality to include BIG-IP DNS (formerly GTM) and possibly other areas. Both the LTM module and the parent BIG-IP module are projects on github. Please use these projects to report any issues you discover. Thanks! The module contains the following functions. Add-iRuleToVirtualServer Add-iRuleToVirtualServer Add-PoolMember Add-PoolMonitor Disable-PoolMember Disable-VirtualServer Enable-PoolMember Enable-VirtualServer Get-CurrentConnectionCount (deprecated; use Get-PoolMemberStats | Select-Object -ExpandProperty 'serverside.curConns') Get-F5Session (will be deprecated in future versions. use New-F5Session) Get-F5Status Get-HealthMonitor Get-HealthMonitorType Get-iRule Get-iRuleCollection (deprecated; use Get-iRule) Get-Node Get-BIGIPPartition Get-Pool Get-PoolList (deprecated; use Get-Pool) Get-PoolMember Get-PoolMemberCollection (deprecated; use Get-PoolMember) Get-PoolMemberCollectionStatus Get-PoolMemberDescription (deprecated; use Get-PoolMember) Get-PoolMemberIP (deprecated; use Get-PoolMember) Get-PoolMembers (deprecated; use Get-PoolMember) Get-PoolMemberStats Get-PoolMemberStatus (deprecated; use Get-PoolMember) Get-PoolMonitor Get-PoolsForMember Get-StatusShape Get-VirtualServer Get-VirtualServeriRuleCollection (deprecated; use Get-VirtualServer | Where rules | Select -ExpandProperty rules) Get-VirtualServerList (deprecated; use Get-VirtualServer) Invoke-RestMethodOverride New-F5Session New-HealthMonitor New-Node New-Pool New-VirtualServer Remove-HealthMonitor Remove-iRule Remove-iRuleFromVirtualServer Remove-Pool Remove-PoolMember Remove-PoolMonitor Remove-ProfileRamCache Remove-Node Remove-VirtualServer Set-iRule Set-PoolLoadBalancingMode (deprecated; use Set-Pool) Set-PoolMemberDescription Set-Pool Set-VirtualServer Sync-DeviceToGroup Test-F5Session Test-Functionality Test-HealthMonitor Test-Node Test-Pool Test-VirtualServer How to use this snippet: To use the module, click 'Download Zip', extract the files, and place them in a folder named F5-LTM beneath your PowerShell modules folder. By default, this is %USERPROFILE%\Documents\WindowsPowerShell\Modules. The WindowsPowerShell and Modules folders may need to be created. You will most likely need to unblock the files after extracting them. Use the Unblock-File PS cmdlet to accomplish this. The Validation.cs class file (based on code posted by Brian Scholer) allows for using the REST API with LTM devices with self-signed SSL certificates. Nearly all of the functions require an F5 session object as a parameter, which contains the base URL for the F5 LTM and a credential object for a user with privileges to manipulate the F5 LTM via the REST API. Use the New-F5session function to create this object. This function expects the following parameters: The name or IP address of the F5 LTM device A credential object for a user with rights to use the REST API An optional TokenLifespan value for extending the life of the authentication token past the default 20 minutes You can create a credential object using Get-Credential and entering the username and password at the prompts, or programmatically like this: $secpasswd = ConvertTo-SecureString "PlainTextPassword" -AsPlainText -Force $mycreds = New-Object System.Management.Automation.PSCredential "username", $secpasswd Thanks to Kotesh Bandhamravuri and his blog entry for this snippet. There is a function called Test-Functionality that takes an F5Session object, a new pool name, a new virtual server, an IP address for the virtual server, and a computer name as a pool member, and validates nearly all the functions in the module. I've also contributed this code sample for how to gather some basic info about your LTM with this PS module. The module has been tested on: 11.5.1 Build 8.0.175 Hotfix 8 and later 11.6.0 Build 5.0.429 Hotfix 4 and later 12.0 / 12.1 13.0 Code : https://github.com/joel74/POSH-LTM-Rest Tested this on version: 11.5iRules Editor & Declarative Development with Visual Studio Code
The windows iRule Editor has had a very long life. But...it hasn't been updated in years and really should be sunsetted in your environment. There have been other attempts along the way, from a personal project with a Mac desktop app written in python and Qt that never made it past me, an Eclipse plugin several years back that gained a little traction, but the iRule Editor Joe Pruitt created lived on through all of that. However, there are a couple fantastic options now in the Visual Studio Code marketplace that combine to make for a great iRules development environment and also include the ability to pursue the automation toolchain development as well. Here are the tools you'll need: Visual Studio Code F5 Networks iRules (for iRules command completion and syntax highlighting) The F5 Extension (for session management and soooo much more) ACC Chariot (for converting config from UCS upload to AS3) John Wagnon and I had Ben Gordon on our DevCentral Connects live stream a couple times to highlight the functionality, which as mentioned goes far beyond just iRules.
iCR Python Module for iControl REST
Problem this snippet solves: This is a python module to simplify using iControl REST. Install using pip: pip install iCR or retrieve from https://pypi.python.org/pypi?:action=display&name=iCR&version=2.1 As simple as: #!/usr/bin/env python from iCR import iCR bigip = iCR("172.24.9.132","admin","admin") virtuals = bigip.get("ltm/virtual") for vs in virtuals['items']: print vs['name'] This prints out a list of Virtual Servers. Supported methods: init(hostname,username,password,[timeout,port,icontrol_version,folder,token,debug]) get(url,[select,top,skip,filter]) -> returns data or False getlarge(url,size,[select]) -> Used to retrieve large datasets in chunks. Returns data or False create(url,data) -> returns data or False modify(url,data,[patch=True]) -> returns data or False delete(url) -> returns True or False upload(file) -> file is a local file eg /var/tmp/test.txt, returns True or False download(file) -> files are located in /shared/images, returns True or False create_cert(files) -> files is an array containing paths to cert and key. Returns name of cert or False get_asm_id(name) -> name is the name of a policy. Returns an array of IDs or False create_hash(name) -> name is the name of the partition and policy. eg /Common/test_policy. This reduces the need to retrieve an array of hashes from the BIG-IP. Returns a string. get_token() -> this retrieves a BIG-IP token based on the username and password and sets it as the token in use. Returns the token ID or False delete_token() -> This deletes the object token from the BIG-IP and from the object create_transaction() -> creates a transaction and returns the transaction number ID as a string, or False. Subsequent requests will be added to thetransaction until commit_transaction is called. Transaction ID is stored in object.transaction commit_transaction() -> Commits the transaction stored in object.transaction. Returns True or False command(args,[cmd]) -> Runs a command using the arguments string args. Returns the returned output or True on success or False on failure. Note:Be sure to double-escape single quotes eg \\' and single escape double quotes eg \" cmd options are ping/save/load/restart/reboot Module Variables: icr_session - the link to the requests session raw - the raw returned JSON code - the returned HTTP Status Code eg 200 error - in the case of error, the exception error string headers - the response headers icontrol_version - set this to specify a specific version of iControl debug - boolean True or False to set debugging on or off port - set the port ( 443 by default ) folder - set this to create in a specific partition token - use this to set a specific token. If this is set, it will be used instead of basic auth select - use this with get to select the returned data top - use this with get to return a set number of records skip - use this to skip to a specific record number transaction - stores the Transaction ID How to use this snippet: Examples Setup a REST connection to a device #!/usr/bin/env python from iCR import iCR bigip = iCR("172.24.9.132","admin","admin",timeout=10) Create a Virtual Server vs_config = {'name':'test_vs'} createvs = bigip.create("ltm/virtual",vs_config,timeout=5) Retrieve the VS we just created virt = bigip.get("ltm/virtual/test_vs",select="name") print "Virtual Server created: " + virt['name'] Set the timeout bigip.timeout = 20 Now delete the VS we just created delvs = bigip.delete("ltm/virtual/test_vs") Retrieve ASM policy to ID mapping policies = bigip.get("asm/policies",select="name,id") Print a table of ASM policies with learning mode print print "Policy Name Learning Mode" print "------------------------------------------" for item in policies['items']: enabled = bigip.get("asm/policies/" + item['id'] + "/policy-builder",select="learningMode") print '{:32}'.format(item['name']) + enabled['learningMode'] File upload fp = "/home/pwhite/input.csv" if bigip.upload(fp): print "File " + fp + " uploaded" File download file="BIGIP-12.1.2.0.0.249.iso" download = bigip.download(file) if not download: print "File " + file + " download error" SSL Certificate creation In different folder bigip.folder = "TestFolder" files = ("TestCert.crt","TestCert.key") cert = bigip.create_cert(files) if cert: print "Certificate " + cert + " created" Turn on debugging bigip.debug = True Retrieve ASM policy IDs asm = bigip.get_asm_id("dummy_policy") print len(asm) + " IDs returned" print "ID: " + str(asm[0]) Convert an ASM policy name to hash hash = bigip.create_hash("/Common/test-policy") enabled = bigip.get("asm/policies/" + hash + "/policy-builder",select="learningMode") print '{:32}'.format(item['name']) + enabled['learningMode'] Retrieve and use a token bigip.get_token() Delete the token bigip.delete_token() Developed on Python 2.7 but works with v3. Works on TMOS 11.6 onwards though some features may not be implemented, such as tokens. If you use this and have found bugs, would like to discuss it or suggest features then please PM me on DevCentral. Tested this on version: 13.0
