How to check active connections in icontrol ?

Hi, I need a help regarding F5 icontrol... When I disable a node using icontrol in powershell,it is disabled.I want to check the current connections on that node after disabling,I mean post disabling the node,for how much time it will have active connections ?I cannot find any predefined command in icontrol cmdlets for checking the active connections. Can anyone help ?

    Please use iControl REST API with 

    Invoke-RestMethod
    like below with your 
    username
    ,
    password
    and 
    bigip
    .

    PS> $securePwd = ConvertTo-SecureString "password" -AsPlainText -Force
PS> $credential = New-Object System.Management.Automation.PSCredential("username",$securePwd)

    you can see nodename list 

    PS> Invoke-RestMethod -Uri https://bigip/mgmt/tm/ltm/node/stats -Credential $credential | Format-List

    And you can see the stats of specified node with

    PS> Invoke-RestMethod -Uri https://bigip/mgmt/tm/ltm/node/{target-nodename}/stats -Credential $credential | Format-List

    Try this and you can see nodename list 

    Invoke-RestMethod -Uri https://bigip/mgmt/tm/ltm/node/stats -Credential $credential | Format-List

    And you can see the stats of specified node with

    Invoke-RestMethod -Uri https://bigip/mgmt/tm/ltm/node/{target-nodename}/stats -Credential $credential | Format-List

    Hi Uchi, It seems to be working :) Thanks a lot!!!

     

    In the same way, can we check the virtual server and pool stats or are there any other commands or syntaxes ?

      Hi Uchi, I ran the following command to check the current connections on a active node .....where, I replaced bigip with bigip ip address and replaced target node with the node name

       

      Invoke-RestMethod -Uri {target node}/stats -Credential $credential | Format-List

       

      The following is the result the I am receiving post executing the above command..

       

      kind : tm:ltm:node:nodestatsgeneration : 1selfLink : {target node}/stats?ver=11.6.1entries : @{addr=; curSessions=; monitorRule=; monitorStatus=; tmName=; serverside.bitsIn=; serverside.bitsOut=; serverside.curConns=; serverside.totConns=; sessionStatus=; status.availabilityState=; status.enabledState=; status.statusReason=; totRequests=}

       

      So, do I need to add any of the above entries in the Invoke-Restmethod command or here itself should I see all the node stats.

       

      Please bear with me,as I am new to API

       

      Thanks

      You have already get all the node stats. Please change 

      Format-List
      to 
      ConvertTo-Json -Depth 10
      and then you can see all of data recursively.
