How can I create member with name using powershell cmdlet?
How can you create pool members with descriptive names? When I create a new vm, I'm able to automatically add it to a pool. Add-F5.LTMPoolMember -Pool $PoolName -Member "${VMIP}:${Port}" However the name of the node is its ip address. I've also tried using the more low level way of adding a node $PoolList = @($PoolName) $Node = New-Object -TypeName iControl.CommonAddressPort; $Node.address = $VMIP $Node.port = $Port (Get-F5.iControl).LocalLBPool.add_member_v2($PoolList, $Node) I can't find any way to change the node name with add_member_v2
Query Current Connections at the Node Level
I am working on Powershell scripts to do automated deployments to our servers behind our BIG-IP LTM. I have simple scripts that use the iControl powershell cmdlets Disable-F5.LTMNodeAddress -Node xxx.xxx.xxx.xxx These work quite well, however, what I need next is a way to query the Current Connections to the node as they bleed off so that my automation doesn't begin the deployment until current connections = 0. I'm assuming I'm just not formatting my searches right as someone must have figured this out by now. Any help would be greatly appreciated. Thanks!
iControlRest - Using Powershell's Invoke-RestMethod to obtain connections stats from pool members?
Hi, I'm hoping someone can help here, I'm 2 days and counting and have hit a brick-wall on it. I personally have doubts if this can work, although I'd like to think it is possible. I'm writing a script in Powershell to monitor the serverside.curConns value and return it using Powershell. The plan is to incorporate this into a bigger script to allow a server reboot once the value reaches 0 At the moment, we have 8 (and growing) servers in this pool, and the idea is to run this on each server when it goes to do a system restart during patching. I only want to change the values at the top of my script, so this script will remain unchanged across the 8 servers when copied locally. For example, lets say the 8 servers are named... PROD_SERVER01 to PROD_SERVER08 My script is below. ======= CHANGE PER ENVIRONMENT ========== $f5partition = "Production" $f5poolname = "Frontend_App_pool" $f5port = 8080 $user = "myf5userid" $pass = "myf5password" $f5server = "myf5server.mydomain.local" ======= NO CHANGES BELOW THIS LINE! ======= $servername = $env:COMPUTERNAME ====== AUTHORISATION SECTION ========== $pair = "$($user):$($pass)" $encodedCreds = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes($pair)) $basicAuthValue = "Basic $encodedCreds" $Headers = @{ Authorization = $basicAuthValue } === CONNECT TO F5 API ========= $reply = Invoke-RestMethod -Uri https://${f5server}/mgmt/tm/ltm/pool/~${f5partition}~${f5poolname}/members/~${f5partition}~${servername}:${f5port}/stats/?$select=serverside.curConns -Headers $Headers My JSON results will look like this...Just like the ones detailed in the IControlRest pdf manual...results below truncated for readability... { "generation": 263285, "kind": "tm:ltm:pool:members:membersstats", "selfLink": "https://localhost/mgmt/tm/ltm/pool/~Production~Frontend_App_pool/members/~Production~PROD_SERVER01:8080/stats?ver=12.1.3", "entries": { "https://localhost/mgmt/tm/ltm/pool/~Production~Frontend_App_pool/members/~Production~PROD_SERVER01:8080/~Production~PROD_SERVER01:8080/stats": { "nestedStats": { "kind": "tm:ltm:pool:members:membersstats", "selfLink": "https://localhost/mgmt/tm/ltm/pool/~Production~Frontend_App_pool/members/~Production~PROD_SERVER01:8080/~Production~PROD_SERVER01:8080/stats?ver=12.1.3", "entries": { "serverside.curConns": { "value": 0 } } } } } } If I run the script above once, I then have the JSON loaded into the $reply variable. Using Powershell ISE, if I then construct a WRITE-HOST statement and start typing, the remaining will fill in automatically. For example, I started with $reply. then the first entry is $reply.entries and so on, until I can find what I want... Write-Host $reply.entries.'https://localhost/mgmt/tm/ltm/pool/~Production~Frontend-App_pool/members/~Production~PROD_SERVER01:8080/~Production~PROD_SERVER01:8080/stats'.nestedStats.entries.'serverside.curConns'.value This will display the value to the screen My problem is that I am having trouble writing the script to run on PROD_SERVERS02-08, because that above WRITE-HOST statement uses fixed properties. I've tried lots of variable substitutions on this line to no avail. I'm also struggling to do anything constructive with enumerating through the multi-tiered JSON in a loop to extract the value. Any help greatly received! Thanks in advance. I'm trying to write something that doesn't have any baggage with it, so not downloading curl .exes or pre-built functions to cart around server-to-server. Neil
Find a node using LocalLBNodeAddressV2 based on IP address (not name)
Hello. We have some iControl PowerShell scripts that we're using with our Private Cloud (IaaS) platform to add/remove VIPs, Pools and Nodes. Previously we were using LTM v10 so we couldn't set a friendly name for the node. Once we upgraded to v11 we started to set the "name" to match the actual server name. So for example we might have SERVER0121 as the node's Name and 192.168.1.17 as the node's address. It has been working fine, but now we've run into a situation where we have stale data - servers that are in the F5 but should have been removed and never were. So we're running into the following error: Exception calling "create" with "3" argument(s): "Exception caught in LocalLB::urn:iControl:LocalLB/NodeAddressV2::create() Exception: Common::OperationFailed primary_error_code : 17237812 (0x01070734) secondary_error_code : 0 error_string : 01070734:3: Configuration error: invalid node address, the IP address 10.27.197.106 already exists" So I'd like to be able to remove these stale entries as we see them. But I'm not sure how to remove this node based on IP address only. For example if I try delete_node_address using the IP address. Exception calling "delete_node_address" with "1" argument(s): "Exception caught in LocalLB::urn:iControl:LocalLB/NodeAddressV2::delete_node_address() Exception: Common::OperationFailed primary_error_code : 16908342 (0x01020036) secondary_error_code : 0 error_string : 01020036:3: The requested node address (/Common/10.27.197.117) was not found." At line:1 char:1 + (Get-F5.iControl).LocalLBNodeAddressV2.delete_node_address($server_ip); + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : SoapHeaderException It's expecting the "name" which is SERVER0117. So how do I remove the node based only on IP address? Thanks. Rezilient
Clearing of RAM-Cache or Web Acceleration profiles
I need a way to clear the web cache from off box. I'm playing around with PowerShell for iControl but don't see any ramcache related commands listed. I found a sample script the references the 'Get-RAMCacheEntry' command but this doesn't seem to exist any more. Basically, I need a good way of doing what this command does without giving my application people CLI access to the big-ip. tmsh delete ltm profile ramcache [cache profile name] Ideas? Thanks, PatrickPowershell and iControl : ManagementDeviceGroup.get_list
Hi, We are using Powershell and iControl to make some job on our F5 BigIP. I am trying to get the Group Device list with the follow commands line : 01 $f5_server_01 = "servername" 02 $f5_user_01 = "admin" 03 $f5_password_01 = "password" 04 $ic_01 = New-Object iControl.Interfaces 05 $ic_01.initialize("$f5_server_01", "$f5_user_01", "$f5_password_01") 06 $ic_01.ManagementDeviceGroup.get_list() When every thing is ok, the last line (06) should return something like this : /Common/HA-Sync /Common/device_trust_group /Common/gtm But some time to time, it is retunring nothing, and I have to wait a while before it come back 😞 Is anyone already get this problem ? Is there any iControl limitation ? Thank for you help. JB
How do I read the send string for a monitor using powershell icontrol?
I have an (unknown) number of monitors that look at an asp page. I need to create an equivalent monitor for each of these that looks at the new htm page. My thought was to script this using powershell and icontrol. I want to look at all the send string on each monitor on an LTM, if the send string contains the name of the asp page, create a new monitor based on that monitor name referencing the new htm page. But I can't seem to pull the send string off the monitor. I've googled around and i see examples for listing, adding and removing monitors - but not listing the details of a monitor. I'm currently (failing) using the following: $sv = New-Object -TypeName iControl.LocalLBMonitorStringValue $sv.type = 'STYPE_SEND' $monitorname = 'rollout' $Control.locallbmonitor.get_template_user_defined_string_property(@($monitorname),@($sv.type)) I get the following error: Exception calling "get_template_user_defined_string_property" with "2" argument(s): "Exception caught in LocalLB::urn:iControl:LocalLB/Monitor::get_template_user_defined_string_property() Exception: Common::OperationFailed primary_error_code : 16908342 (0x01020036) secondary_error_code : 0 error_string : 01020036:3: The requested monitor parameter (rollout_HTTPS 1 STYPE_SEND=) was not found."
