editsqlite
editThis is a community-maintained plugin! It does not ship with Logstash by default, but it is easy to install by running bin/logstash-plugin install logstash-input-sqlite
.
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" }

Details
edit
batch
edit- Value type is number
-
Default value is
5
How many rows to fetch at a time from each SELECT
call.
codec
edit- 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.
exclude_tables
edit- Value type is array
-
Default value is
[]
Any tables to exclude by name. By default all tables are followed.
path
edit- This is a required setting.
- Value type is string
- There is no default value for this setting.
The path to the sqlite database file.
tags
edit- 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
edit- 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 Kibana.
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.
