/home/logs/app.log,07:14:09,534 INFO - DeviceCmd::writeException::handled::appKey::xxx::iid::gT07Jklck::deviceId::8f2ecac6

as you did not share your Graylog version I assume you have the latest running. What you want to make is an aggregation on the message, that is part of the enterprise plugins for alerting.
