Re: [akka-user] In an Akka cluster, can I programmatically discover which node has a particular cluster singleton?

(I'm not clear if you have N singletons, that they all reside on the same node though?) Yes, unless you give tell some of them to be on a specific role. As seen in  http://doc.akka.io/docs/akka/current/scala/cluster-singleton.html#An_Example -- Konrad -- >> Read the docs:

Re: [akka-user] In an Akka cluster, can I programmatically discover which node has a particular cluster singleton?

Okay, I was starting to pursue just asking which node in the cluster was the oldest. Seems like the singletons ought to migrate to that node? (I'm not clear if you have N singletons, that they all reside on the same node though?) On Tue, May 17, 2016 at 4:47 PM, Justin du coeur

Re: [akka-user] In an Akka cluster, can I programmatically discover which node has a particular cluster singleton?

I suspect the most straightforward way to do this is to send a message to the singleton and ask it which node it's living on. Granted, that makes the test a bit less black-box... On Tue, May 17, 2016 at 4:29 PM, Steve Rehrauer wrote: > I have a few cluster singletons.

[akka-user] In an Akka cluster, can I programmatically discover which node has a particular cluster singleton?

I have a few cluster singletons. One in particular can hold a fair bit of state. While doing load-tests, I want a way to discover which node's heap use is contributed to by that singleton. Is there a programmatic way to, from a sequence of the cluster nodes and the singleton's proxy actor
