I like the correlation and the alerting. If I have multiple monitoring systems and I alert Graylog, Graylog will collect them and analyze them, and issue one alert.
We are only approximately four months into production and have not explored all of the features this solution offers. So far, it has everything we wanted.
I would like to see some kind of visualization included in Graylog. The report is plain, they could be improved.
I have been using Graylog for approximately five months.
We are using the latest version.
Graylog community is very good.
We are also using Zenoss.
The initial setup is straightforward.
It's an open-source solution that can be used free of charge.
I would definitely recommend Graylog to others who are interested in using it.
At this point with the features that I have used, I would rate Graylog a ten out of ten.
