How to use FTP or SCP to retrieve log files
An Administrator or Device User can use FTP or SCP to retrieve a tab-delineated event log file (event.txt) or
data log file (data.txt) and import it into a spreadsheet.
• The file reports all events or data rec orded since the log was last deleted or tr uncated because it reached
maximum size.
• The file includes information that the event log or data log does not display.
– The version of the file format (first field)
– The date and time the file was retrieved
–The Name, Contact, and Location values and IP address of the NMC
– The unique Event Code for each recorded event (event.txt file only)
The NMC uses a four-digit year for log entries. Y ou may need to se lect a four -digit date
format in your spreadsheet application to display all four digits.
If you are using the encryption-based security protocols, see “To use SCP to retrieve the files”. If you are usin g
unencrypted authentication methods for security, see “To use FTP to retrieve the files”.
See the Security Handbook, available on the Network Management Card Utility CD and on the
website (www.apc.com) for information on available protocol s and me th ods for setting up the type
of security you need.
