Can I use a single appd java agent to monitor multiple tiers?

[rraju1990]

Hi,

I'm running multiple tiers (all JVMs) in my laptop, therefore trying to see if I can use a single Java agent to monitor all tiers? If it's not possible, can I use a single Java agent to monitor all the nodes in a specific tier? I will be using a custom POJO entry point and custom corelation as well.

 You can use one agent installation to monitor as many JVMs as you like on a single server.

Just take care that you give each JVM a unique node name with the -Dappdynamics.agent.nodeName system property

Warm regards,

Thanks, Peter. 

I haven't tested this yet, but clarifying it to be on the safe side. Custom correlation needs to be done differently per tier as far as I understood, so how do we do this if we use a single agent to monitor multiple tiers?

Just set the tier names for your JVMs appropriately, again with the system properties.

Tiers are entirely a logical construct; co-hosting JVMs makes no difference.

To be absolutely clear here, you have a single agent install on the filesystem.  Each JVM, however, will contain an independent running agent so from a runtime perspective you really have one agent per JVM

Warm regards,
Peter.
