Facilitates backend service monitoring with efficient log retrieval and API flexibility

Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.

It's a user-friendly open-source solution that can replace or augment a commercial product in some cases

I rate syslog-ng 10 out of 10. It's free and easy to use. It has built-in tools that help us index the various logs sent to it. It's a solid log product. If you're looking for a SIEM solution, syslog-ng will work as a stopgap measure at beginning of the project. It can also work as an injector for a true SIEM solution. You can send all the logs to syslog-ng and forward all the data to the SIEM solution after you've cleaned up the data and got the pertinent information. It's a good front end for a commercial SIEM solution, which becomes more expensive as you load more data into it. I would highly recommend syslog-ng for that use case. However, if you lack the expertise, you might need to go with a cloud-based SIEM instead. You need some in-house expertise or an outside consultant to manage it and set it up.

Quotes from Members

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

Pros

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

"Message forwarding through the in-built module."

"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."

"I like the correlation and the alerting."

"I am very proud of how very stable the solution is."

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

"Everything stands out as valuable, including the fact that I can quantify and qualify the logs, create pipelines and process the logs in any way I like, and create charts or data maps."

More Graylog Enterprise pros

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

"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."

"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 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."

Cons

"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."

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

"Dashboards, stream alerts and parsing could be improved."

"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."

"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."

"Its scalability gets complicated when we have to update or edit multiple nodes."

"The area in Graylog that needs to be improved or enhanced would be the integrations."

"When it comes to configuring the processing pipeline, writing the rules can be very tedious, especially since the documentation isn't extensive on how the functions provided for these rules work."

More Graylog Enterprise cons

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

"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."

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

"The filtering has room for improvement."

Pricing and Cost Advice

"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."

"Having paid official support is wise for projects."

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

"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."

"I use the free version of Graylog."

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

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

"Consider Enterprise support if you have atypical needs or setup requirements."
