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 > ------------------------------------------------- > > Key: IGNITE-6867 > URL: https://issues.apache.org/jira/browse/IGNITE-6867 > Project: Ignite > Issue Type: New Feature > Reporter: Aleksey Plekhanov > Assignee: Pavel Pereslegin > Labels: iep-6, jmx > Fix For: 2.4 > > > These additional metrics and methods should be implemented: > * Current topology version > * Total server nodes count > * Total client nodes count > * Method to count nodes filtered by some node attribute > * Method to count nodes grouped by some node attribute > > There is already a ticket to implement first 2 metrics from this list > (IGNITE-6844) -- This message was sent by Atlassian JIRA (v6.4.14#64029)
