Aria Operations for Networks version 6.11 appliances fail to rotate the log causing /var/log partition to grow beyond 90 Percent

Logrotate service has issues in rotating logs for nginx, syslog, warn, etv.

Log files of syslog, warn and nginx grows and consumes disk space causing disk out of space issues. 

  1. syslog keeps writing to syslog.1 instead of syslog file. (Location is /var/log/)
  2. syslog keeps writing to warn.1 instead of warn file. (Location of log is /var/log/)
  3. nginx keep writing to access.log.1 instead of access.log file (Location of log is /var/log/nginx/)

Since the service is writing to file with '1', logrotate never performs the log rotation, because it checks the main file for rotation and its always empty.
It doesn't perform rotation on empty files and hence syslog.1, warn.2, access.log.1 files grows bigger and bigger.




VMware Aria Operations for Networks 6.11.0


After log rotation is performed it triggers a reload call to the respective service to reload the log files, so that it will continue to write to correct file.
This mechanism is broken and as a result files grow huge in size making /var/log >90%


Aria Operations for Networks Engineering team is aware of this and a patch on top of Aria Operations for Networks Version 6.11 is made available which fixes the log rotation issue.

  1. Login to each Appliance VM as username support
  2. Execute the following commands:
    sudo su
    mkdir -p /usr/local/lib/python3.6/dist-packages/cli
    ln -sf /usr/local/lib/python3.8/dist-packages/cli/ /usr/local/lib/python3.6/dist-packages/cli/
