Senior Software Engineer at Absa Bank Uganda

Centralized log insights have reduced investigation time and improve security response

One improvement I want to see in Graylog Enterprise is artificial intelligence to help us automatically identify unusual patterns and suggest possible causes. I also want to see more ready-made dashboards and alert templates for common security use cases to help us gain value from the platform faster after deployment. Lastly, I want to see improvements in handling very large volumes of data, especially after searching, and a more user-friendly log management system, particularly in large environments. I give Graylog Enterprise a 9 out of 10 because it has a limitation of a steep learning curve for new users due to the many configuration options. It takes considerable time to become comfortable with creating searches, dashboards, and alerts. Additionally, in very large environments with large volumes of logs, it requires careful planning, and its data retention is quite limited.

Oliver Castellucchio

IT Infrastructure & Cloud Security Manager at Thux

Has ensured compliance by centralizing log data and supporting secure connections

We currently do not use that feature. We currently have just an open-source release, not a premium release. My boss has indicated that he wants to buy a premium syslog-ng version next month. I think we can use other features of this tool in the future. In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"We run a containerized microservices environment, and being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."

"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."

"With Graylog Enterprise, monitoring improved by up to 80 percent because of having all the logs centralized."

"The solution's most valuable feature is its new interface."

"I like the simplicity of the solution, the fact that it's open source and user friendly."

"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."

"The product is scalable. The solution is stable."

"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."

More Graylog Enterprise pros

"Syslog-ng has a separate config file in addition to the core configuration."

"We chose syslog-ng because it is easy to install, easy to maintain, easy to update, and due to the fact that all data arrive in raw format, we can manipulate it as we want."

"What I appreciate most about syslog-ng is its configuration; its C-style config is much easier to understand, read, and write than other popular solutions such as syslog or rsyslog."

"The ability to extract and store the logs is the most valuable feature of syslog-ng."

"For us, the most valuable feature is the use of compound search for searching logs at a specific time, by a specific user, or specific behavior."

"Syslog-ng provides easy access to all my logs. It helps me show managers and other clients precisely where an incident occurred. I also like it because you can integrate syslog-ng with multiple solutions to allow real-time monitoring."

"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."

Cons

"More customization is always useful."

"I would rate them as a two out of 10. You are on your own without an enterprise license."

"There are many other applications in the market that influenced my rating reduction."

"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"

"If you have a whole team trying to fix the Graylog instance for two days, that's a bit too much."

"We ran into problems with Elasticsearch throwing a circuit-breaking exception due to field data size being too large. It turned out that the heap size directly impacted this size in a high-throughput environment, causing unexplained instability in Graylog. We were able to troubleshoot on the Elasticsearch size, but we should have been able to reference some minimum requirements for Graylog to know that our settings weren't sufficient."

"Lacks sufficient documentation."

"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them. Other SIEM solutions have basic rules and you can create and get more events of interest."

More Graylog Enterprise cons

"The filtering has room for improvement."

"There is room for improvement in terms of observability."

"There is always the potential for additional integration and protocol extensions."

"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."

"It's hard to find people who know how to use syslog-ng. I often find problems with configurations, and solutions aren't integrated correctly with syslog-ng. For example, there might be data with extra decimals, or the collector agents are incorrectly named. It isn't a problem with the solution; it's a lack of professionals."

Pricing and Cost Advice

"It's an open-source solution that can be used free of charge."

"I use the free version of Graylog."

"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."

"We are using the free version of the product. However, the paid version is expensive."

"Having paid official support is wise for projects."

"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."

"If you want something that works and do not have the money for Splunk or QRadar, take Graylog."

"You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
