Dmitry Karachentsev updated IGNITE-8759: ---------------------------------------- Fix Version/s: 2.7 > TcpDiscoverySpi: detailed info about current state in MBean > ----------------------------------------------------------- > > Key: IGNITE-8759 > URL: https://issues.apache.org/jira/browse/IGNITE-8759 > Project: Ignite > Issue Type: Improvement > Components: general > Reporter: Sergey Chugunov > Assignee: Dmitry Karachentsev > Priority: Major > Labels: discovery > Fix For: 2.7 > > > When TcpDiscoverySpi is used all nodes keep information about current > topology locally. Discovery protocol is responsible of keeping this > information consistent across all nodes. > However in situations of network glitches some nodes may have different > pictures of current state and topology of the cluster. > To make it easier to monitor state of the whole cluster and identify such > nodes quicker the following information should be presented via MBean > interface on each node: > * Current topology version; > * Hash of current topology (e.g. sum of hash codes of all nodeIds) (to allow > quick matching); > * Pretty-formatted snapshot of current topology visible from the node; > * Information about nodes visible/invisible to local one; > * Other information useful to monitoring of topology state. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
