Viewing the Cache Log

To view the Media Flow Controller cache log:
•
Web interface—Media Flow Controller cache log entries are available for viewing on the
Web interface Logs > Cache Logs page.
•
CLI—To upload a cache log, run upload cachelog scp://<URL>. Now you can access the
cache log at the specified system, move it (if needed) and view its contents. See
"Terminology" on page 30

Error Log (errorlog)

The Media Flow Controller errorlog records service related error messages, such as cache
and delivery problems; this log is for Technical Support debugging. The Media Flow Controller
system log (syslog) records system related messages and errors, such as user logins and
CPU problems; see
Logs (CLI)" on page 226
page 210.
By default, the errorlog name is "error.log." If Media Flow Controller is launched from the serial
console, all error messages print out on the console; if Media Flow Controller is launched from
the CLI, all error messages are logged in the file /var/log/messages.
The Error Logs provide freeform information; including these fields:
•
Date and time, in brackets
•
Media Flow Controller module and message level in this form: module.level, in brackets
(see tables
descriptions); module code may not display.
•
Function name and source line number (ends with colon)
