Getting real Join Time on a node

[renzos]

Hi guys,

I'm running a cluster with 4 physical nodes, and I need to get some stats on node join time. So far I tried to get that (with milliseconds precision) in this way:

long startTime=new Date().getTime();

Cache<Object, Object> cache = manager.getCache("benchCache");

long endTime=new Date().getTime();

long result=endTime-startTime;

And now I was wondering if there's a way to get the join time with more precision, inside infinispan, maybe with an Interceptor.

Any help is appreciated a lot

Thanks.

That will only work if that's the first cache to be retrieved from the cache manager, which results in the JGroups join.

It's a bad practice to use Date for that. For elapsed measurements, use System.nanoTime() which is geared towards that use case - http://imagocomputing.blogspot.com/2010/04/compute-elapsed-time-in-nanoseconds.html

I can't think of other solutions right now.
