apache_error

The apache_error parser plugin parses apache error logs.

Parameters

keep_time_key

If you want to keep time field in the record, set true. Default is false.

types

Although every parsed field has type string by default, you can specify other types. This is useful when filtering particular fields numerically or storing data with sensible type information.

The syntax is

types <field_name_1>:<type_name_1>,<field_name_2>:<type_name_2>,...

e.g.,

types user_id:integer,paid:bool,paid_usd_amount:float

As demonstrated above, "," is used to delimit field-type pairs while ":" is used to separate a field name with its intended type.

Unspecified fields are parsed at the default string type.

The list of supported types are shown below:

• string

• bool

• integer ("int" would NOT work!)

• float

• time

• array

For the time and array types, there is an optional third field after the type name. For the "time" type, you can specify a time format like you would in time_format.

For the "array" type, the third field specifies the delimiter (the default is ","). For example, if a field called "item_ids" contains the value "3,4,5", types item_ids:array parses it as ["3", "4", "5"]. Alternatively, if the value is "Adam|Alice|Bob", types item_ids:array:| parses it as ["Adam", "Alice", "Bob"].

Regexp patterns

This is regexp pattern of this plugin:

format /^\[[^ ]* (?<time>[^\]]*)\] \[(?<level>[^\]]*)\](?: \[pid (?<pid>[^\]]*)\])? \[client (?<client>[^\]]*)\] (?<message>.*)$/

level, pid, client and message are included in the event record. time is used for the event time.

Example

[Wed Oct 11 14:32:52 2000] [error] [client 127.0.0.1] client denied by server configuration

This incoming event is parsed as:

time:
971242372 (Wed Oct 11 14:32:52 2000)

record:
{
  "level"  : "error",
  "client" : "127.0.0.1",
  "message": "client denied by server configuration"
}
