See Parse Section Configurations.

Regexp Patterns

Here is the regexp and time format patterns of this plugin:

expression /^(?<remote>[^ ]*) (?<host>[^ ]*) (?<user>[^ ]*) \[(?<time>[^\]]*)\] "(?<method>\S+)(?: +(?<path>[^\"]*?)(?: +\S*)?)?" (?<code>[^ ]*) (?<size>[^ ]*)(?: "(?<referer>[^\"]*)" "(?<agent>[^\"]*)"(?:\s+(?<http_x_forwarded_for>[^ ]+))?)?$/
time_format %d/%b/%Y:%H:%M:%S %z

remote, user, method, path, code, size, referer, agent and http_x_forwarded_for are included in the event record. time is used for the event time.

Example

This incoming event:

127.0.0.1 192.168.0.1 - [28/Feb/2013:12:00:00 +0900] "GET / HTTP/1.1" 200 777 "-" "Opera/12.0" -

is parsed as:

time:
1362020400 (28/Feb/2013:12:00:00 +0900)

record:
{
  "remote"              : "127.0.0.1",
  "host"                : "192.168.0.1",
  "user"                : "-",
  "method"              : "GET",
  "path"                : "/",
  "code"                : "200",
  "size"                : "777",
  "referer"             : "-",
  "agent"               : "Opera/12.0",
  "http_x_forwarded_for": "-"
}
