ApacheLog

Import can read all common variants of the Apache log format, as well as Wolfram MathLM log files and user-customized log formats.

Background & Context

Import["file","ApacheLog"] imports an Apache log file.
Import["file","ApacheLog"] reads an Apache log file and returns the contents as a table.
Import["file",{"ApacheLog",elem}] imports the specified element from an Apache log file.
Import["file",{"ApacheLog",{elem₁,elem₂,…}}] imports multiple elements.
The format "ApacheLog" must always be specified when importing Apache log files.
See the following reference pages for full general information:
Import import from a file

CloudImport import from a cloud object

ImportString import from a string

ImportByteArray import from a byte array

General Import elements:
"Elements" list of elements and options available in this file

"Summary" summary of the file

"Rules" list of rules for all available elements
Data representation element:
"Data" content of the file represented as a list of lists
Import by default uses the "Data" element for Apache log files.
Selecting individual data fields:

	"Attachments"	files attached to the message
	"ByteCount"	byte size of the object returned to the client
	"Date"	date and time of the transaction, given as a string
	"Referrer"	site from which the client reports having been referred
	"RemoteHost"	IP address or hostname of the client
	"RemoteUser"	user ID of the client as determined by HTTP authentication
	"RequestLine"	the client request as a string, normally containing the path of the requested object and information about the protocol
	"SessionID"	a string that identifies the user session
	"StatusCode"	the status code that the server returns to the client, as defined in the HTTP specification (RFC2616)
	"UserAgent"	browser identification as reported by the client

Import option:
"DataFormat" Automatic format specification, given as a list of data representation elements and separators representing one record
To import a custom log format, "DataFormat" can be used to specify the format of each record as a combination of data elements and record separators.
Import of Common Log files uses the setting "DataFormat"->{"RemoteHost"," ","ClientID"," ","RemoteUser"," " ,"Date"," \"","RequestLine","\" ","StatusCode"," " ,"ByteCount"}.
The default format of Access Log files is given by {"RemoteHost"," ","ClientID"," ","RemoteUser"," " ,"Date"," \"","RequestLine","\" ","StatusCode"," " ,"ByteCount", " \"","Referrer","\" \"","UserAgent","\""}.
