RabbitMQ - not writing logs?

[Sean Bollin]

Is this normal?  0 bytes to rab...@myhost.log and rab...@myhost-sasl.log?

Cluster has been running fine for months until today we get a network partition.  Try to look at the logs and the main files haven't been written to for months?

SASL log can be blank for a while (only unhandled exceptions are logged to it)

but standard log certainly can't, e.g. by default it logs inbound connections.

Hmm ok, will take a look.  Perhaps these inactive log files are on the 2 out of 3 nodes in the cluster that aren't being used ......

Same issue i have facing also.. i cant see any server specific logs . Only sasl log file contains some log.  Is there any config parameter need to be enabled to get logs?

[Michael Klishin]

Log levels are configurable but just about everything RabbitMQ can log is logged by default.

See http://www.rabbitmq.com/configure.html.

Does restarting your node help? There were bugs in the past that could break logging

but the last of those that I can recall was in the 3.4.x days:
