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.

A scalable and affordable tool for monitoring data centers
Five engineers are needed for the maintenance of the product. I would definitely recommend the solution to those planning to use it. To increase the rating for the product, Nagios should offer remote support and offer more customization in reporting while making it easy for the customers to use it. Overall, I rate the solution an eight out of ten.

Quotes from Members

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

Pros

"Graylog is worth the given effort."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"The centralized logs where one can find bugs quicker and find the line of code that is a problem has made us more efficient."
"The product is scalable. The solution is stable."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"Graylog is very handy."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"A great feature of the solution involves its internal portal."
"My company is a featured partner of Nagios XI, so I'm implementing Nagios XI in different companies and supporting the product, and I'd recommend the solution because it offers a lot of benefits and has a good dashboard, it's pretty easy to get up and running, and the pricing is good."
"One of the most valuable features is the dashboard because the UI was effective and easy to use. The alert systems are good as well. We had no failovers and had high availability. We can search the queries fast as well in Nagios Log Server."
"The product is scalable."
"The initial setup of Nagios Log Server was easy and straightforward."
 

Cons

"The area in Graylog that needs to be improved or enhanced would be the integrations."
"I would rate them as a two out of 10. You are on your own without an enterprise license."
"The initial setup was really complex because I did it myself."
"The support from the Graylog community is helpful, but they can do better."
"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them. Other SIEM solutions have basic rules and you can create and get more events of interest."
"Lacks sufficient documentation."
"I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"The support could be better. They only offer email support."
"The configurations during initial setup could be improved."
"The configurations during initial setup could be improved. If they could be agentless, as in the case of the Ansible product, it would be better. I would like to be able to analyze the network bandwidth."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
 

Pricing and Cost Advice

"​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."
"We are using the free version of the product. However, the paid version is expensive."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"For a single instance, the price is around $4,000."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"We found the pricing to be quite affordable."
