APM variables? (or how to query virtual hosts and more)

In APM, when setting up HTTP(S) Monitors, I need to query a virtual host, however using the format of https://${IP}:${PORT}/path it makes the request using the IP address. While that seems appropriate, since it's using ${IP}, I need it to pass the hostname in order to get to the correct path. I've tried ${DNS}, but that appears invalid for APM. Is there a list of acceptable variables to select from or at a minimum is there a variable to use the name instead?

On a somewhat related issue, I have a second variable that I've been unable to determine. When creating alerts I've added a link to the object having the issue as seen below. However I've not found the correct variable for "AM:327". Any assistance on this issue would be appreciated as well.

foo/.../MonitorDetails.aspx

Thanks

You have to use APM:Component in "Type of property to monitor" in "Trigger condition" for alert if you want to use ${ComponentId}. This variable is not available if you use APM:Application alert.

Hi Corey.

1. NetObject=AM:327 refers to the component ID, represented by the alert variable ${ComponentID}

2. The URL field recognizes only ${IP} and ${PORT}. You'll have to hard code the actual hostname in there.

Just to clarify Roger's answer, ${ComponentId} is just numeric part. You have to use it as foo/.../MonitorDetails.aspx

Roger,

I've tried in the past and it doesn't work. Here is a recent alert I recieved. You can see I was trying to see if it was case sensitive, but it did not do any substitutions.

${ComponentID}
${ComponentId}

I'm surprised that the URL field doesn't support any other variables. It is an issue when using virtual hosts. We monitor several status pages within virtual hosts and since the request isn't hostname based it's a limitation to us. Sure I can edit each one, but it kinda defeats the purpose of it being a template.

jiri,

Yes, I knew that, but thanks for the clarification.

Perfect! That is what I was missing.

Thank you.
