@jerrypeng : heh, yep, I read the whole bug before my first reply. And it
had this note:
* "immediateFlush - When set to true - the default, each write will be
followed by a flush. This will guarantee the data is written to disk but could
impact performance."
And *that* is what scared me into replying actually! The log4j2 docs
should probably just be updated to "written to disk or network".
> Storm syslog logging not confirming to RFC5426 3.1

> Key: STORM-1519
> URL: https://issues.apache.org/jira/browse/STORM-1519
> Project: Apache Storm
> Issue Type: Bug
> Reporter: Boyang Jerry Peng
> Priority: Minor
>
> AS per RFC 5426 section 3.1, there should be only one message per datagram:
> 3.1. One Message Per Datagram
> Each syslog UDP datagram MUST contain only one syslog message, which
> MAY be complete or truncated. The message MUST be formatted and
> truncated according to RFC 5424 [2]. Additional data MUST NOT be
> present in the datagram payload.
> For example
> UDP package: <174>1 2016-02-02T22:44:05.558Z localhost [nimbus] - [nobody:S0]
> [mdc@18060 ClassName="?"] Using custom scheduler:
> backtype.storm.scheduler.bridge.MultitenantResourceAwareBridgeScheduler
> <174>1 2016-02-02T22:44:05.591Z localhost [nimbus] - [nobody:S0] [mdc@18060
> ClassName="?"] Creating new blob store based in /home/y/var/storm/blobs
> but the two log messages should be each in their own udp packet
