Добрый день.

Автотесты работают в связке Jenkins + java + testng + selenium grid.

Иногда возникают какие-то проблемы, вероятно, сетевые, но может быть и проблемы с нехваткой памяти или процессора.

Суть вопроса: как узнать, какая нода виновата?

 

Например, ошибка:

По revision или по Session ID определить ноду невозможно, т.к. Grid Console выдает только вот такую информацию:

А разве

host:192.168.2.182

не то, что вам надо?

Именно, но в логах ничего такого нет. 

Grid Console привел пример для 1 ноды, их несколько. Как узнать, какая?

Просто обновитесь, версия 2.35 достаточно старая. Сейчас сообщения об ошибках содержат больше информации и выглядят примерно так:

Вы не поверите, но у меня везде на нодах и на хабе запускается селениум версии 2.42.0. Почему в логах пишется 2.35 - непонятно :(

Скачал 2.42.2, буду пробовать.
