We performed a comparison between Graylog and syslog-ng based on real PeerSpot user reviews.
Find out in this report how the two Log Management solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."I am very proud of how very stable the solution is."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"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."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"The solution's most valuable feature is its new interface."
"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."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"Syslog-ng has a separate config file in addition to the core configuration."
"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."
"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."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"There should be some user groups and an auto sign-in feature."
"Dashboards, stream alerts and parsing could be improved."
"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-"
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"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."
"With technical support, you are on your own without an enterprise license."
"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."
"The filtering has room for improvement."
"There is always the potential for additional integration and protocol extensions."
"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."
"There is room for improvement in terms of observability."
"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."
