JMX matrices and audit logs serve completely different purposes.

Yup, I know, but I was thinking about exporting those metrics to systems like
Graphite or Nagios that can keep a record of ops exposed (given the right
adapters), those views in fancy dashboards. But you right: they are
complementary. *I would even go further to suggest that we could have JMX
commands to enable/disable the audit log.* ;)

Audit logs does not log all the operations, they log only the operations which
change the state of the system.
{quote}
Even so, this can be *a LOT of operations (state changes)*. _THIS, in fact is
my only point regarding this issue_, but I am all favour about the prospect of
adding an audit log. Even on previous comment about it (sorry, if I was unclear
about that).

When the audit log is disabled, the performance impact is negligible. But when
audit log is enabled offcourse there will be slight performace degradation
{quote}
Sure. Let's do this and *measure* his performance degradation under a high load
of write ops, so that users can be aware of its impact.
TL;DR: I am +1 about adding an audit log, we certainly need this.

> Lots of users have had questions on debugging which client changed what znode
> and what updates went through a znode. We should add audit logging as in
> Hadoop (look at Namenode Audit logging) to log which client changed what in
> the zookeeper servers. This could just be a log4j audit logger.
