------------------------------------------
Summary: Log information about inaccessible nodes through
Communication
Key: IGNITE-11425
URL: https://issues.apache.org/jira/browse/IGNITE-11425
Project: Ignite
Issue Type: Improvement
Reporter: Vladislav Pyatkov
In case of long getting communication TCP client (longe than this
CONNECTION_ESTABLISH_THRESHOLD_MS = 100) message will printed:

but in some cases we can not to get client during time out, and the message
reduce to
TCP client created [client=null, duration=60004 ms]
According to the message you cannot understand which nodes were inaccessible.
Moreover, wants to see the connection trouble earlier than the 10 minutes after.
Should to log ip/host for clear understanding what was the node and log WARN
message each time when need to increase timeout:
{code}
if (lastWaitingTimeout < 60000)
lastWaitingTimeout *= 2;
{code}
