What are the main differences between Graylog2 and Kibana?
We already use Graylog2 but I must admit I don't really like the UI. Just wonder in case it may be helpful to switch to Kibana.
At my company we started with Graylog2 and recently installed Kibana3. My personal opinion is that Kibana3 is more suited towards non-dev, while Graylog isn't.
Kibana:
Graylog2
We still have Graylog2 running in parallel to Kibana3, but I don't think it will last for much longer. Kibana3 provides most, if not all, of the capabilities (that we needed), and on top of that it allows management friendly interfaces.
