Likelihood to Recommend For small companies, Graylog is the best solution possible. It's easy to configure and "just works." Above everything else, it's free. The only thing I hold against it is the fact that it's Linux-based. [This] makes sense because Elasticsearch is Linux-based. But Linux adds a layer of complexity that we don't need for something basic as a logging server. I'm pretty sure that we would have had a logging server years earlier if I had to convince quite a few decision-making people to go ahead with it anyway.
Read full review Kibana integrates seamlessly with Elastic Search which gives us access to parse and analyze data generated from our systems in order to make decisions. Also, Kibana helps us create insightful reports and dashboards that give us insights into the end-users usage on the system and helps us find the root cause of issues as well.
Read full review Pros Graylog does a great job of its core function: log aggregation, retention, and searching. Graylog has a very flexible configuration. The backend for storage is Elasticsearch and MongoDB is used to store the configuration. You have to option to make your configuration as simple as possible by storing everything on one box, or you can scale everything out horizontally by using a cluster of Elasticsearch nodes and MongoDB servers with several Graylog servers pointed to all the necessary nodes. Graylog does a good job of abstracting away a fair portion of Elasticsearch index management (sharding, creation, deletion, rotation, etc). Read full review Fast searches with powerful index. Beautiful data visualizations. Real-time observability. Read full review Cons Support for more log sources Event alerts/emails - Some cases where unable to separate data from multiple clients, and no easy fix API - Limits results to 10,000 and can cause server to lockup on queries that exceed the limit Read full review Some performance issues with large datasets. Linking to dashboards makes extremely long urls. Lack of reports. Read full review Support Rating Community support does not give simple straightforward answers; simply search up Graylog Issues and look at some of the responses on the forums. The documentation is your only hope if you are on the free version, as you can NOT purchase only support. The few times I have worked with Graylog Enterprise support they were great though.
Read full review We did not use the official Kibana support. Documentation was easy enough to follow.
Read full review Alternatives Considered In terms of log aggregation, the free product fully stacks up with the competitors listed. Full control over the data ingests for flexible configuration. Graylog even better on that front than
AlienVault USM because you cannot configure the variable mapping. We haven't used the threat exchange stuff or correlation. But with regex searches, we have created function dashboards that show threat theater pictures of our network based on logs from our firewall.
Read full review Kibana has a better usability experience, the core features I was using existed in all of them. I liked more in Kibana how you can easily create dashboards, charts, and reports without the need to be a tech person.
Read full review Return on Investment Graylog is just less expensive than some other options which meant it fit into our budget otherwise we might not be able to justify a higher cost. Being able to track issues that we normally couldn't track using other tools is a bonus to help us know of any issues we have and can fix before an outage or failure that could potentially cost money. We have had to spend more time than I would like to understand and customize Graylog which has taken time away from other tasks and projects. Read full review Issues that affect checkout experiences for customers are able to be prioritized and solved quickly. We are able to more efficiently use resources due to the automation of reporting alerts. Decreasing employee resources needed. Visualization allows us to quickly share issues and explain to coworkers in order to escalate issues that can cost our bottom line. Read full review ScreenShots
