logstash-jdbc

This is an old version of the plugin, for Logstash v1.4 only. It is no longer receiving backports of fixes and contains several flaws which have been addressed in the Logstash v2 compatible versions, and above. Please upgrade/see the other branches in the source repository.

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

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" ]
	}
}
