Graylog Pros and Cons

I am very proud of how very stable the solution is.

Graylog's search functionality, alerting functionality, user management, and dashboards are useful.

Open source and user friendly.

I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second.

Graylog can improve the index rotation as it's quite a complex solution.

Lacks sufficient documentation.
