This is the release announcement for the fourth beta of the new line of development of Graylog2, 0.21. This version underwent big redesigns of major parts to increase its testability and therefore – in the long run – its stability.
We have also put some effort into making the REST API more usable by returning consumable (JSON) error messages and extracting high level Java artifacts to help others developers making use of it.
Other than that we have a number of new features, which include:
Support for configurable alarm callbacks per stream, which are called when an alert condition is triggered for a stream. It is already coming with support for templatable e-mails and http calls. Support for configurable message outputs, to allow forwarding of complete streams to another Graylog instance. A new and more extensive plugin API which offers the possibility to extend with your own (and 3rd party) inputs, message filters, alarm callbacks and message outputs. All inputs which are not queue-based deliver incoming messages into a newly designed MapDB-based input buffer if the internal ring buffer has reached its capacity. This input buffer is persisted to disk to prevent message loss in case of a crash. This helps to reduce memory usage especially during peak loads while not losing any messages during runtime. Inputs are now pausable and resumable using the web interface or the REST API. The data model has not changed since 0.20.x, so an in-place upgrade of your installation is possible. If you encounter any errors or unexpected behaviour, please make us aware of it by reporting this to the mailing list or create an issue on Github.
Since the first and second beta release of 0.21 we have fixed a number of issues concerning startup/shutdown of the server and general message processing performance in situations with unreliable name resolving.
Since the third beta release of 0.21 we have fixed one bug which made the search unusable in some cases and another bug which broke logging in to the web interface.
