HTTP monitors - wild cards?

robert777

Received a requirement for some HTTP monitors. Normally simple stuff - SW has out of the box templates for that.

Except... system owner has several servers with similar web pages running on each. So... rather than just

myurl/newwebsite.internal

its

https://<fqdn of server>/newwebsite.internal

I really don't want to make several web monitor components - one for each server.

Can you / is it possible to include a wildcard in a web monitor URL, like

https://{HOSTNAME}/newwebsite.internal ?

I welcome any inputs from the community.

Thank you!

Playing around with this I suspect the solution will be some kind of Powershell script monitor that uses invoke-webrequst rather than the out of box HTTP monitor.

Let me know if any ideas from the community. Thanks.

I think I figured this one out.

Unless I am mistaken the out-of-box http monitor does not let you insert the host name in the URL. This requires a standard PowerShell monitor. Here is the solution that appears to work.

$hostname = "${Node.Caption}"

$url = "https://" + $hostname + ".mycompany.internal:9876/website-name"

$req = [system.Net.WebRequest]::Create($url) 

try {
    $res = $req.GetResponse()
} 
catch [System.Net.WebException] {
    $res = $_.Exception.Response
}

$StatusCode = $res.StatusCode.value__ 

$MessageText = "Web Response Code"

# send the status code back to Solarwinds
 write-host "Message: $MessageText"
write-host "Statistic: $StatusCode"

Full disclosure: I didn't figure this out on my own. Found it on Stack Overflow. See entry #4 in this thread.
