Graylog2 is an open source log management solution implementation that stores your logs in ElasticSearch, an open Source, distributed, RESTful, search engine built on top of Apache Lucene.
It consists of a server written in Java that accepts your syslog messages via TCP or UDP and stores it in the database. The second part is a Ruby on Rails web interface that allows you to view the log messages.
The web interface uses Ruby On Rails, the server is written in Java.
Graylog2 has been in development since May 2010.
Key Features
- Web interface:
- Search and filter data.
- Streams – saved searches that allow you to quickly access an overview that is pre-filtered.
- Get alerts when the amount of new log messages reaches a defined maximum.
- Create streams for every API consumer and quickly filter errors of certain consumers.
- Send a log message for every activity a user performs in your application.
- Accepts standard syslog via TCP/UDP and GELF via UDP.
- Send in both formats via AMQP (AMQP Docs).
- Graylog Extended Log Format (GELF):
- Libraries and log appenders for Ruby, PHP, Python, Perl/Log4Perl, Java/Log4j (gelf4j, gelfj), Log4r, .NET/log4net, node.js, NLog, Logback plugin, resque, systemd, and Rack.
- Handles hundreds of millions of log events and terabytes of data.
