Cons
Email notification should be done the same way as Logentries does it.We set up a cron job to delete old logs so that we wouldn't hit a disk space issue. Such a feature should be available in the UI, where old logs can be deleted automatically. (Don’t know if this feature is already there).They don't provide user authentication and authorisation features (Shield) as a part of their open-source version.Authentication is not a default in Kibana. We need to have another tool to have authentication and authorization. These two should be part of Kibana.We had issues with scalability. Logstash was not scaling and aggregation was getting delayed. We moved to Fluentd making our stack from ELK to EFK.

It needs to improve the way to install third-party apps and enable installation without logging into splunk.com.I think the machine learning should be emphasized. Now, it's really important to analyze Big Data, data mining. A SIEM solution, like Splunk, needs an improved data mining solution, artificial intelligence.Missing capability for audio/video and image processing.While scheduled reports can be embedded, Splunk dashboard can not be embedded directly without enabling cross origin.DMC should be a little more intuitive with better dashboarding. Seeing the cause of data flow can be tough to track down.Splunk can improve regex/asset analysis as we do not want to crawl until it is done.It can be tough to get a hold of somebody in technical support depending on the complexity of the issue.The Enterprise Security app could be improved. We have had trouble with it working from the first day.

However, there is added value in what it can do, not just log aggregation.Splunk is a bit pricier, but the benefits and ROI are huge.It is a pretty high cost solution, but if your organization has the funds, it can bring many benefits.Personnel costs are saved by not having to involve the domain developers from multiple teams when tracing a problem that spans multiple platforms.Truly evaluate the data you want to ingest and go slow. Pulling in data that can provide no use to your mission only wastes data against your license.Our ROI is high.
