I am working on a java application running in Ubuntu Server (16.04) which copies log files from certain folders and consolidate then when user closes the session. In ubuntu server rsyslog filters and keeps generating logs from different devices (external) and stores logs in a folder.
After the files copied by java application I need to rotate the logs. For that I am planning to use logrotate program. I created a config to rotate this files once a session is closed (user triggers this by closing the session in application).
The files created in the folder (/media/content/persist/log/external/) as below:
-rwxr-xr-x 1 syslog syslog 283 Jul 1 20:49 192.168.10.100-syslog.log -rwxr-xr-x 1 syslog syslog 24K Jul 1 21:25 192.168.10.11-syslog.log -rwxr-xr-x 1 syslog syslog 8.6K Jul 1 21:25 192.168.10.10-syslog.log -rwxr-xr-x 1 syslog syslog 439K Jul 1 21:40 192.168.10.12-syslog.log Log rotate config: **File: rsyslog-fc-rotate.conf **
/media/content/persist/log/external/*-syslog.log { rotate 4 maxsize 5M compress missingok notifempty postrotate invoke-rc.d rsyslog rotate > /dev/null endscript } When I run logrotate manually I am getting the result below without any rotation is being happend

Not sure why it is failing.
In my application with this config, for every session close the files needs to be rotated. This logrorate call will be coming from a java service.
