Hi all, in order to illustrate to you a full overview about how change the all logs files related to Cloudera Manager Agents (v 5.12), I want to share with you guys my particular situation and how I solved it.   I wanted modify the default path logs for the following log files links with Cloudera Manager Agent:   - supervisord.out - supervisord.log (these are the supervisor's logs, this service start up with the Cloudera Manager Agent service the first time when the server start up or when we start up manually the cloudera-scm-agent service. If you stop the Cloudera Manager Agent service but the server remain up, this service remain up also).   - cmf_listener.log (this is a cmf_listener service's logs, this service start up with the Cloudera Manager Agent service the first time when the server start up or when we start up manually the cloudera-scm-agent service. If you stop the Cloudera Manager Agent service but the server remain up, this service remain up also (managed by supervisord).   - cloudera-scm-agent.log - cloudera-scm-agent.out (These are the cloudera-scm-agent logs…)   Below the files that I've modified in order to set a new path for these logs with a dedicated file-system: /usr/lib64/cmf/agent/build/env/lib/python2.7/site-packages/cmf-5.12.2-py2.7.egg/lib/cmf/agent.py (set a new path for the logs: supervisord.out; cmf_listener.log and supervisord.log. Furthermore, check if the parameter for cloudera libraries agent is present in order to avoid unexpected errors with the start up of supervisord (default_lib_dir = '/var/lib/cloudera-scm-agent')) /usr/lib64/cmf/agent/build/env/lib/python2.7/site-packages/cmf-5.12.2-py2.7.egg/cmf/agent.py (set a new path for the logs: supervisord.out; cmf_listener.log and supervisord.log. Furthermore, check if the parameter for cloudera libraries agent is present in order to avoid unexpected errors with the start up of supervisord (default_lib_dir = '/var/lib/cloudera-scm-agent')) /etc/default/cloudera-scm-agent(set a new path for the cloudera agent logs as arguments: CMF_AGENT_ARGS="--logdir=/your/custom/cloudera-scm/user/writable/directory/" and set also CMF_AGENT_ARGS="--lib_dir=/var/lib/cloudera-scm-agent", in order to avoid unexpected errors with the start up of cloudera-scm-agent (As suggested by Harsh 😉). /etc/cloudera-scm-agent/config.ini (set a new path for the cloudera agent logs: log_file=/your/custom/cloudera-scm/user/writable/directory/ and set also lib_dir=/var/lib/cloudera-scm-agent, in order to avoid unexpected errors with the start up of cloudera-scm-agent)   /etc/init.d/cloudera-scm-agent (set a new path for cloudera-scm-agent.out modifying the following parameter: AGENT_OUT=${CMF_VAR:-/var}/log/cloudera/$prog/$prog.out). In my case I left the logs into /var/log but I mounted a dedicated file-system on the folder /var/log/cloudera/ for all these logs.   If you want to stop all the processes related to Cloudera Manager Agent, you should perform the following steps:   service cloudera-scm-agent stop (Stop Cloudera Manager Agent process) ps -eaf | grep cmf (Show the supervisord parent process) root      77977      1  0 13:09 ?        00:00:00 /usr/lib64/cmf/agent/build/env/bin/python /usr/lib64/cmf/agent/build/env/bin/supervisord root      77983  77977  0 13:09 ?        00:00:00 python2.7 /usr/lib64/cmf/agent/build/env/bin/cmf-listener -l /var/log/cloudera/cloudera-scm-agent/cmf_listener.log /run/cloudera-scm-agent/events   kill -15 77977 (Stop supervisord and cmf_listener processes). I used kill -15 because I didn't found another way to stop these processes…   I would like so much if anyone from Cloudera's Engineers can confirm/amend the procedure that I just described above...   Cheers!   Alex   ...
