Server-Side Logging¶
Standalone - Redirect Output to file¶
Objective¶
When running the ZTPServer in Standalone Mode, the logs just fill up my console so I’d like to be able to redirect the output to a file.
Solution¶
With INFO level logging:
admin@ztpserver:~# ztps >~/ztps-console.log 2>&1 &
With DEBUG level logging:
admin@ztpserver:~# ztps --debug >~/ztps-console.log 2>&1 &
Explanation¶
Here we invoke the ztps process as usual, however we redirect the stdout messages to a predefined file. Of course, be sure that you have permission to write to the file you have listed.
Apache - View Standard Logs¶
Objective¶
I’m running the ZTPServer as a WSGI under Apache, so where do the logs go?
Solution¶
Typically, you can see each transaction in:
# Ubuntu
admin@ztpserver:~# more /var/log/apache2/access.log
# Fedora
admin@ztpserver:~# more /var/log/httpd/access_log
And the ZTPServer logs will be in:
# Ubuntu
admin@ztpserver:~# more /var/log/apache2/error.log
# Fedora
admin@ztpserver:~# more /var/log/httpd/error_log
Explanation¶
These locations are the default on most standard Apache installs. It might be misleading, but all levels of ZTPServer logging will end up as an Apache error.
