      Grafana vs Splunk
      pros, cons and recent comments
      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.
