---------------------------------------
Summary: Describe healthy cluster behavior guide
Key: IGNITE-28671
URL: https://issues.apache.org/jira/browse/IGNITE-28671
Project: Ignite
Issue Type: Task
Components: documentation
Affects Versions: 2.18
Reporter: Didar Shayarov
Fix For: 2.19
Current General Performance Tips page [1] provides high-level performance
recommendations, but it does not explain what a normal operational state of an
Ignite cluster looks like. It does not explain where an operator should look
first when checking cluster health.
This task adds a short operational health section right after the general
performance tips:
The page should be elaborated with a short troubleshooting-oriented section
describing healthy cluster behavior and how everything should be evaluated
across different Ignite subsystems like cluster state, baseline, partition
consistency, rebalancing, checkpointing, execution queues, transactions, etc etc
The section should reference built-in metrics, system views, logs, and
control.sh checks,
and should distinguish between temporary spikes and sustained degradation.
Suggested section title:
