----------------------------------------
Summary: RnD: better tooling for cluster topology monitoring
Key: IGNITE-26248
URL: https://issues.apache.org/jira/browse/IGNITE-26248
Project: Ignite
Issue Type: Task
Reporter: Sergey Chugunov
h3. *Motivation*
MultiDC support requires considerable changes in TcpDiscovery protocol, so we
need a tooling to better understand what topology looks like from a point of
view of each node.
Moreover, in MultiDC environment chances of split-brain events are higher and a
reliable tool to quickly inspect current topology state is necessary.
h3. Description
Summarize tools already available including output to logs or control.sh
commands. Come up with ideas how to enhance existing tools or add new ones.
Requirements:
# There should be tools working locally on each node (e.g. better logging) as
well as cluster-wide (like control.sh command or metrics).
# Tools should provide information about topology in an easy-to-understand
form. E.g. lists or UUIDs of nodes is not an acceptable form as it is hard to
read UUIDs by naked eye.
