sqlite

Milestone: 1

This is a community-contributed plugin! It does not ship with logstash by default, but it is easy to install! To use this, you must have installed the contrib plugins package.

Read rows from an sqlite database.

This is most useful in cases where you are logging directly to a table. Any tables being watched must have an ‘id’ column that is monotonically increasing.

All tables are read by default except: * ones matching ‘sqlite_%’ - these are internal/adminstrative tables for sqlite * ‘since_table’ - this is used by this plugin to track state.

Example

% sqlite /tmp/example.db
sqlite> CREATE TABLE weblogs (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    ip STRING,
    request STRING,
    response INTEGER);
sqlite> INSERT INTO weblogs (ip, request, response) 
    VALUES ("1.2.3.4", "/index.html", 200);

Then with this logstash config:

input {
  sqlite {
    path => "/tmp/example.db"
    type => weblogs
  }
}
output {
  stdout {
    debug => true
  }
}

Sample output:

{
  "@source"      => "sqlite://sadness/tmp/x.db",
  "@tags"        => [],
  "@fields"      => {
    "ip"       => "1.2.3.4",
    "request"  => "/index.html",
    "response" => 200
  },
  "@timestamp"   => "2013-05-29T06:16:30.850Z",
  "@source_host" => "sadness",
  "@source_path" => "/tmp/x.db",
  "@message"     => "",
  "@type"        => "foo"
}

charset DEPRECATED

  • There is no default value for this setting.

The character encoding used in this input. Examples include “UTF-8” and “cp1252”

This setting is useful if your log files are in Latin-1 (aka cp1252) or in another character set other than UTF-8.

This only affects “plain” format logs since json is UTF-8 already.

codec

  • Value type is codec
  • Default value is "plain"

The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, without needing a separate filter in your Logstash pipeline.

debug DEPRECATED

  • DEPRECATED WARNING: This config item is deprecated. It may be removed in a further version.
  • Value type is boolean
  • Default value is false

exclude_tables

  • Value type is array
  • Default value is []

Any tables to exclude by name. By default all tables are followed.

format DEPRECATED

  • DEPRECATED WARNING: This config item is deprecated. It may be removed in a further version.
  • Value can be any of: "plain", "json", "json_event", "msgpack_event"
  • There is no default value for this setting.

The format of input data (plain, json, json_event)

message_format DEPRECATED

  • DEPRECATED WARNING: This config item is deprecated. It may be removed in a further version.
  • Value type is string
  • There is no default value for this setting.

If format is “json”, an event sprintf string to build what the display @message should be given (defaults to the raw JSON). sprintf format strings look like %{fieldname}

If format is “json_event”, ALL fields except for @type are expected to be present. Not receiving all fields will cause unexpected results.

path (required setting)

  • Value type is string
  • There is no default value for this setting.

The path to the sqlite database file.

tags

  • Value type is array
  • There is no default value for this setting.

Add any number of arbitrary tags to your event.

This can help with processing later.

type

  • Value type is string
  • There is no default value for this setting.

Add a ‘type’ field to all events handled by this input.

Types are used mainly for filter activation.

The type is stored as part of the event itself, so you can also use the type to search for it in the web interface.

If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another Logstash server.
