Grafana provides a powerful and elegant way to create, explore, and share dashboards and data with your team and the world.
Grafana vs Splunk opinions
Grafana is NOT a log monitor. It is only a graphing solution for logs and metrics from many different data sources but you will need solutions to get those logs and metrics in the first place.
It's not a SIEM tool. Rather, it just displays arbitrary data.
