Aleksey Plekhanov commented on IGNITE-6867:
-------------------------------------------
[~vozerov]
# There are "cluster metrics" extend "local node metrics", not "cluster" extend
"local node". For metrics, inheritance seems right to me, since some cluster
metrics senseless for local node.
# Node attribute value is {{Object}}. In the method {{groupNodes}} attribute
value returned without any transformation. But in the method {{countNodes}},
parameter for operation invoked by jconsole will be {{String}} and it is better
to be compared to {{String}} representation of attribute value.
# This will not work. AFAIK, we can't use MXBean returned by operation, at
least in jconsole.
> Implement new JMX metrics for topology monitoring
