Filter Ansible logs on CentOS 7

CentOS 7 and Redhat 7 seem to love shoving logs into /var/log/messages and if you run ansible in-house then it generates a lot of noise and if you run Splunk or ELK then getting your logs ‘just right’ is important to O.C.D type levels!

To send your ansible generated logs to /var/log/ansible.log perform the following:

Create the file /etc/rsyslog.d/ansible.conf

if ( $programname contains "ansible" ) then /var/log/ansible.log
& stop

and if you are creating log files you will want to manage those log files too!
Create the file /etc/logrotate.d/ansible

/var/log/ansible.log {
        rotate 4

And restart / reload rsyslog

service rsyslog restart
