Logging Levels

Enabling W3C logging mode will start jetNEXUS ALB-X recording a W3C compatible log file. A W3C log is an access log for Web servers in which text files are generated containing data about each access request, including the source Internet Protocol ( IP ) address, the HTTP version, the browser type, the referrer page, and the time stamp. The format was developed by the World Wide Web Consortium ( W3C ), an organization that promotes standards for the evolution of the Web.

The file is in ASCII text, with space-delimited columns. The file holds comment lines beginning with the # character. One of these comment lines is a line naming field (providing column names) so that data can be mined.

There are separate files for HTTP and FTP protocols.

HTTP W3C Logging:

None:

W3C logging is off.

Brief:

The fields present are:

#Fields: time c-ip c-port s-ip method uri x-c-version x-r-version sc-status cs-bytes sr-bytes rs-bytes sc-bytes x-percent time-taken x-round-trip-time cs(User-Agent) x-sc(Content-Type).

Full:

This is a more processor-compatible format with separate date and time fields. See the fields summary below for information on what the fields mean. The fields present are:

#Fields: date time c-ip c-port cs-username s-ip s-port cs-method cs-uri-stem cs-uri-query sc-status cs(User-Agent) referer x-c-version x-r-version cs-bytes sr-bytes rs-bytes sc-bytes x-percent time-taken x-round-trip-time x-sc(Content-Type).

Site:

This format is very similar to “Full” but has an additional field. See the fields summary below for information on what the fields mean. The fields present are:

#Fields: date time x-mil c-ip c-port cs-username s-ip s-port cs-host cs-method cs-uri-stem cs-uri-query sc-status cs(User-Agent) referer x-c-version x-r-version cs-bytes sr-bytes rs-bytes sc-bytes x-percent time-taken x-round-trip-time x-sc(Content-Type).

Diagnostic:

This format is filled with all sorts of information relevant to development and support staff. See the fields summary below for information on what the fields mean. The fields present are:

edgeNEXUS w3c Logging:

Client’s Network Address and Port:

This will show the true client IP address along with the port.

Client’s Network Address:

This will show the true client IP address only.

Forwarded-For Address and Port:

This will show the details held in the XFF header including the address and port.

Forwarded-For Address:

This will show the details held in the XFF header including the address only.

Show Statistics in edgeNEXUS Headers:

On:

This will add a edgeNEXUS header and include gzip compression statistics. Example: edgeNEXUS: version 3.42.1.1475, 1232/4014 (69%)

Off:

This will turn off statistics within the header but the header will still be present. Example: edgeNEXUS: version 3.42.1.1475, On, [Laptop Demo 1 Primary]

Hidden:

No edgeNEXUS header shown at all.

Remote Log Storage

All W3C logs are stored compressed on the jetNEXUS ALB-X every hour. The oldest files will only be deleted when 30% of disk space is remaining. Should you wish to export these to a remote server for safekeeping you can configure that below using an SMB share. Please note that the W3C log will not transfer to the remote location until after the file has been completed and compressed. As the logs are written every hour this could take up to 2 hours for a Virtual Machine and will be 5 hours behind for a hardware appliance. We will include a test button in future releases to previde some feed back that your settings are correct.

Remote Log Storage:

Tick the box to enable remote log storage.

IP Address:

Add in the IP address of your SMB server. This should be in dotted decimal notation. Example: 10.1.1.23

Share Name:

Add in the share name on the SMB server. Example: w3c.

Directory:

Add in the directory on the SMB server. Example: /log.

Username:

Add in the username for the SMB share.

Password:

Add in the password for the SMB share.
