Syslog-ng offers unmatched flexibility in data parsing and filtering, ideal for complex environments, along with superior customization and real-time monitoring capabilities.

Room for Improvement: Graylog Enterprise could improve in areas related to deeper integration with other platforms, enhanced real-time data analytics, and scalability for extremely high data volumes.

Log analysis has become clearer and faster but visualization and extensibility still need work

The problem was with the complexity and the cost to add extensions. We found this very expensive to buy another version with additional features. I think that Graylog Enterprise does not have customizable dashboards. I did not see them in Graylog Enterprise because most of the time we used the open source free version, which is limited. I think Graylog Enterprise should improve some things that they have in the paid version and perhaps provide users with a menu that gives examples of parsing logs and draws graphics so that people do not need to improve another system such as Grafana. This would be interesting. When it comes to functionalities, I found the log management in Graylog Enterprise acceptable. It is very simple to use and to collect logs. It has support for different protocols and different ports, and the sidecar is easy to use. However, in visualization, I think it needs to be much better.

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're using the Community edition, but I know that it has really good dashboarding and alerts."

"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."

"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."

"Message forwarding through the in-built module."

"We have scaled from a single machine installation (a VM with a Graylog + ES + MongoDB) to (2 Graylog + 2 ES + 3 MongoDB). This was done smoothly with a minimal impact on logging."

"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."

"It has data adapters and lookup tables that utilize HTTP calls to APIs."

"I like the correlation and the alerting."

More Graylog Enterprise pros

"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."

"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."

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

"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."

"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."

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

"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."

Cons

"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."

"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."

"More customization is always useful."

"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."

"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-"

"With technical support, you are on your own without an enterprise license."

"Elasticsearch recommendations for tuning could be better. Graylog doesn't have direct support for running the system inside of Kubernetes, so it can be challenging to fill in the gaps and set up containers in a way that is both performant and stable."

"There should be some user groups and an auto sign-in feature."

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."

"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."

Pricing and Cost Advice

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

"We're using the Community edition."

"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."

"I am using a community edition. I have not looked at the enterprise offering from Graylog."

"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."

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

"I use the free version of Graylog."

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