Clean Up Log Data
As jobs are executed on the system, a number of logs are generated, which need to be cleaned up, otherwise
they may consume unnecessary space. Log data is useful for debugging issues, but if it is certain that this data is
no longer needed, it can be deleted.
●
Mesos logs - Mesos logs are stored under
var/log/mesos
, whereas the Mesos framework logs are stored
under
/var/log/mesos/agent/slaves
. These logs need to be deleted manually.
●
Marathon logs - Marathon logs are stored under
var/log/message
and need to be deleted manually.
●
HA Proxy logs - HA Proxy logs are stored under
var/log/message
and need to be deleted manually.
●
Jupyter logs - Juypter log file are located at
var/log/jupyterhub/jupyterhub.log
and need to be
deleted manually.
