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

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

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

"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."

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

"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."

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

"The build is stable and requires little maintenance, even compared to some extremely expensive products."

"What I like about Graylog is that it's real-time and you have access to the raw data. So, you ingest it, and you have access to every message and every data item you ingest. You can then build analytics on top of that. You can look at the raw data, and you can do some volumetric estimations, such as how big traffic you have, how many messages of data of a type you have, etc."

More Graylog pros

"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 a separate config file in addition to the core configuration."

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

"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."

Cons

"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."

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

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

"I would like to see some kind of visualization included in Graylog."

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

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

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

"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 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."

"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."

"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

"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 use the free version of Graylog."

"We're using the Community edition."

"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."

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

"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."
