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.

Efficient log management enhances activity monitoring despite VPN user issue
Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users. When a VPN user logs in, it doesn't really capture the time before this. If you're testing with existing or new device integration, then the product will be good in the market.

Quotes from Members

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

Pros

"I like the simplicity of the solution, the fact that it's open source and user friendly."
"The best feature of Graylog is the Elasticsearch integration; we can integrate and run filters, such as an event of interest, and those logs we can send to any SIEM tool or use as analytics, and there are clear and well-documented implementation instructions on their website to follow if needed."
"It is easier to find some issues, and if I find some issues, then it is easier to resolve them."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"The ability to write custom alerts is key to information security and compliance."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"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."
"I am very proud of how very stable the solution is."
"Our primary use case for this solution is detecting issues to provide customers with information."
"ManageEngine EventLog Analyzer was a lower-cost alternative, and it was easier to install and manage."
"The tool's reports show activities."
"What I found most useful in ManageEngine EventLog Analyzer is its integration with other ManageEngine applications. It seamlessly integrates throughout the ManageEngine suite, and that's beneficial. I also like that the solution has chain management capabilities, it has a modular approach, and it's easy to reach the support team."
"It's one of the easiest products. It's very simple to use."
"The initial setup is straightforward"
"The log management has helped to improve my organization."
"The most valuable features of ManageEngine EventLog Analyzer are the number of capabilities, file integration monitoring, web server log collection, and alert configuration."
 

Cons

"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."
"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."
"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them."
"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."
"I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"With technical support, you are on your own without an enterprise license."
"I would like to see some kind of visualization included in Graylog."
"For Python developers, it would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"What I'd like to see as an improvement to ManageEngine EventLog Analyzer is for it to be more AI-driven."
"The first tier of customer service and support is not great."
"Last month, we faced an issue with a Hawaiian VPN user activity."
"It may not be as easy to use as Splunk."
"The solution is stable. However, there are limits. For example, we can do 2,500 Syslog events per second, but if we want to do more we have to install the distributor structure, and then we can expand how many events we can do. They could improve the stability."
"Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users."
"There isn't good security integration when it comes to cybersecurity. The correlation of logs isn't so simple."
"There isn't good security integration when it comes to cybersecurity. The correlation of logs isn't so simple."
 

Pricing and Cost Advice

"I use the free version of Graylog."
"It's open source and free. They have a paid version, but we never looked into that because we never needed the features of the paid version."
"We are using the free version of the product. However, the paid version is expensive."
"We're using the Community edition."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"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."
"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."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."
"There is a license required for these solutions. The customer can choose the license type, such as an annual license purchase or a perpetual license. If the customer wants maintenance they will have to pay annually."
"Licensing for ManageEngine EventLog Analyzer is paid yearly."
"ManageEngine EventLog Analyzer is expensive. Its licensing costs are annual."
"We paid for the license of the solution and the deployment. The price of ManageEngine EventLog Analyzer is less expensive than other solutions."
