RabbitMQ disk is full /var/log/rabbitmq

Issue/Introduction

RabbitMQ nodes, by default, append all log data to persistent files. Unlike message data, log files are not self-cleaning. Without an active rotation strategy, log files will grow indefinitely until they consume all available disk space on the disk.

Verify if the disk utilization is due to logs

/dev/mapper/rootvg-lv_varlog        10G   10G   20K 100% /var/log

-bash-4.4$ ls -lh

Environment

RabbitMQ

Cause

Log rotation is not implimented in RabbitMQ server

Resolution

Do not delete the .log file while the service is running. Use the truncate command instead

truncate -s 0 /var/log/rabbitmq/[email protected]

Permanent solution is to implement log rotation in the RabbitMQ server
