logstash-jdbc

JDBC output plugin for Logstash. This plugin is provided as an external plugin and is not part of the Logstash project.

Currently untested with logstash 1.5+. Support is planned.

Warning

This has not yet been extensively tested with all JDBC drivers and may not yet work for you.

Installation

• Copy lib directory contents into your logstash installation.
• Create the directory vendor/jar/jdbc in your logstash installation (mkdir -p vendor/jar/jdbc/)
• Add JDBC jar files to vendor/jar/jdbc in your logstash installation
• Configure

Configuration options

• driver_class, string, JDBC driver class to load
• connection_string, string, JDBC connection string
• statement, array, an array of strings representing the SQL statement to run. Index 0 is the SQL statement that is prepared, all other array entries are passed in as parameters (in order). A parameter may either be a property of the event (i.e. "@timestamp", or "host") or a formatted string (i.e. "%{host} - %{message}" or "%{message}"). If a key is passed then it will be automatically converted as required for insertion into SQL. If it's a formatted string then it will be passed in verbatim.
• flush_size, number, default = 1000, number of entries to buffer before sending to SQL
• idle_flush_time, number, default = 1, number of idle seconds before sending data to SQL, even if the flush_size has not been reached. If you modify this value you should also consider altering max_repeat_exceptions_time
• max_repeat_exceptions, number, default = 5, number of times the same exception can repeat before we stop logstash. Set to a value less than 1 if you never want it to stop
• max_repeat_exceptions_time, number, default = 30, maxium number of seconds between exceptions before they're considered "different" exceptions. If you modify idle_flush_time you should consider this value

Example configurations

SQLite3

• Tested using https://bitbucket.org/xerial/sqlite-jdbc
• SQLite setup - echo "CREATE table log (host text, timestamp datetime, message text);" | sqlite3 test.db

input
{
	stdin { }
}
output {
	stdout { }

	jdbc {
		driver_class => 'org.sqlite.JDBC'
		connection_string => 'jdbc:sqlite:test.db'
		statement => [ "INSERT INTO log (host, timestamp, message) VALUES(?, ?, ?)", "host", "@timestamp", "message" ]
	}
}

SQL Server

• Tested using http://msdn.microsoft.com/en-gb/sqlserver/aa937724.aspx

input
{
	stdin { }
}
output {
	jdbc {
		driver_class => 'com.microsoft.sqlserver.jdbc.SQLServerDriver'
		connection_string => "jdbc:sqlserver://server:1433;databaseName=databasename;user=username;password=password;autoReconnect=true;"
		statement => [ "INSERT INTO log (host, timestamp, message) VALUES(?, ?, ?)", "host", "@timestamp", "message" ]
	}
}

Postgres
