Set existing monitor on existing node in Powershell - F5 Big-IP

I know how to create a new node in Powershell. I've read you cannot apply a health monitor upon creation. So how can I add a health monitor afterwards? The name of the node is "TestNode1" and the health monitor is default http.

 

Below is what I'm playing with. I think I'm close up until the second argument. No idea what to do there. Thanks for any help!

 

$ic.LocalLBNodeAddressV2.set_monitor_rule("TestNode1",$ic.LocalLBMonitorRule.monitor_rule("http"))

    Hi, have you seen this link?

    https://devcentral.f5.com/questions/using-powershell-to-run-get-f5icontrol-locallbnodeaddressv2set_monitor_rule-command

    I am no expert, this is my test and it works for me:

    Add-PSSnapIn iControlSnapIn
Initialize-F5.iControl -HostName 192.168.1.245 -Credentials (Get-Credential)

$MonitorRule = New-Object -TypeName iControl.LocalLBMonitorRule
$MonitorRule.type = "MONITOR_RULE_TYPE_SINGLE"
$MonitorRule.monitor_templates = @("icmp")

(Get-F5.iControl).LocalLBNodeAddressV2.set_monitor_rule(@("10.10.10.10"), @($MonitorRule))

    Thanks, I had seen that page but it creates the monitor, it doesn't apply an existing monitor. I will give your script a try. Is there a reason you use arrays (@) in this script? Is it necessary to apply a single monitor to a single node? Thanks for the help.

      It sets the icmp monitor as a single monitor to node, it is not creating a new one. My arrays were used just to make it clear that the method signature. Usually, I don't need to monitor the node, I do that in the pool. I hope to have it understood. Regards.

    I am getting this error. This node does exist in common.

     

    $MonitorRule = New-Object -TypeName iControl.LocalLBMonitorRule $MonitorRule.type = "MONITOR_RULE_TYPE_SINGLE" $MonitorRule.monitor_templates = @("icmp") (Get-F5.iControl).LocalLBNodeAddressV2.set_monitor_rule(@("172.22.130.71"), @($MonitorRule))

    I used the node's name instead of IP and it worked. Strange. In other cases, doing other operations, I had to use the node's IP. Any ideas why? Thanks for the help with getting this working. Much appreciated.
