Issue/Introduction

Is an event recorded when an access log upload via FTP fails?
You want to know if an event is recorded when the FTP connection breaks in the middle of transmission.

Resolution

In our tests we concluded that we are not able to determine the FTP client upload status.

We are only able to determine whether the ProxySG is able to connect to the FTP server successfully at the event log. Here's an example event log connecting.

2008-06-06 06:32:11-00:00UTC  "Config admin at 10.109.1.104 'admin', starting a test access log upload per user request for log main"  0 160002:7D   ../cli_parse.hpp:312
2008-06-06 06:32:11-00:00UTC  "Access Log FTP (main):Test Upload: Connecting to primary 10.109.1.187 server 10.109.1.187:21."  0 E0000:96   ../alog_ftp_client.cpp:110
2008-06-06 06:33:26-00:00UTC  "Access Log FTP (main):Test Upload: Couldn't connect control socket to primary server 10.109.1.187"  3C E000A:1   ../alog_ftp_client.cpp:155
2008-06-06 06:33:26-00:00UTC  "Access Log FTP (main):Test Upload: Couldn't connect to primary server"  3C E000A:1   ../alog_ftp_client.cpp:174
2008-06-06 06:33:26-00:00UTC  "Access Log (main): Unable to connect to remote server for log uploading"  0 E0008:1   ../alog_facility_impl.cpp:2715
2008-06-06 06:33:26-00:00UTC  "Access Log (main): Upload retries have been canceled."  0 E0008:96   ../alog_facility_impl.cpp:2742

If the FTP upload was successful, you should see this in the event log:
Log upload successful. Remote file size xxx bytes.

If a Failure to Connect error is seen in the Event logs, then investigations on the network and the Proxy will need to be conducted to get more information. Packet captures taken at the ProxySG and the Destination can be valuable here.
