Automated log rotation on the supervisor and workers is available via a Windows Scheduled Task, launchctl on OS X, and a cron job on Linux.
Setup and configuration
Linux
Setup
No additional tasks are necessary for log rotation on linux.
Configuration
The log rotation on Linux is managed by the linux daemon
logrotated , and is specified in /etc/logrotate.d/supervisor . See the man pages for logrotated if you wish to customize the rotation policies.Rotation Policy
Rotate out the logs weekly, keeping 4 copies.
OS X
Setup
No additional task tasks are necessary for log rotation on OS X.
Rotation Policy
Rotate out the logs when they exceed 100MB in size (the default size in the the logrotate.py script script).
Configuration
The log rotation on OS X is managed by launchctl/launchd, and the associated .plist files are:
/Library/LaunchDaemons/com.pipelinefx.logrotate.supervisor.
plist plist
/Library/LaunchDaemons/com.pipelinefx.logrotate.worker.plist
/Library/LaunchDaemons/com.pipelinefx.logrotate.worker.plist
Both of these plists call /Applications/pfx/qube/utils/logrotate.py; see The logrotate.py script
Windows
Setup
Enabling log rotation on Windows requires that the Python programming language be installed and in the System SEARCH PATH. The easiest way to accomplish this is to download and install a free Community Edition version of Python
from http://www.python.org. Download and run one of these installers, and allow it to add Python to the System Search Path. You should see the logs rotate out within the hour. If you're unsure which version to install, choose the 64-bit installer.
Python 2.7 64-bit: http://downloads.activestate.com/ActivePython/releases/2.7.2.5/ActivePython-2.7.2.5-win64-x64.msi
Python 2.7 32-bit: http://downloads.activestate.com/ActivePython/releases/2.7.2.5/ActivePython-2.7.2.5-win32-x86.msi
Configuration
All Scheduled Tasks call
%QBDIR%/pfx/qube/utils/logrotate.py, with only the path to the log as an argument.
Rotation Policy
Rotate out the logs when they exceed 100MB in size (the default size in the logrotate.py
script).
Verifying that log rotation is occurring
Locate the log directory:
- Linux:
/var/log/ - OS X:
/var/log - Windows Vista, 7, Server 2008:
C:\ProgramData\Pfx\qube\logs
You will see at least on workerlog or supelog file. When rotation occurs, these logs are renamed and/or zipped/compressed.
- supelog -> supelog.1
- supelog.1 --> supelog.2.zip
- supelog.2.zip --> supelog.3.zip
- supelog.3.zip --> supelog.4.zip
- supelog.4.zip is deleted
You will only see supelog and supelog.1 the first time the rotation occurs. The other files will appear when additional log rotation cycles occur as time passes.
