[jira] [Commented] (IGNITE-8078) Add new metrics for data storage

["Ivan Daschinskiy (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-8078?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16424282#comment-16424282 ] 

Ivan Daschinskiy commented on IGNITE-8078:
------------------------------------------

[~DmitriyGovorukhin], may be it's better to extend already implemented TcpDiscoverySpiMBean.getCoordinator()? i.e. this method could return String formed by U.toString(ClusterNode) instead of UUID.
