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

"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."

"With Graylog Enterprise, monitoring improved by up to 80 percent because of having all the logs centralized."

"We run a containerized microservices environment. Being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."

"This has increased productivity for the dev and support teams, because we are directly notifying them."

"It has data adapters and lookup tables that utilize HTTP calls to APIs."

"Message forwarding through the in-built module."

"I like the correlation and the alerting."

"Feature-wise or from the end user perspective, Graylog is just great."

More Graylog Enterprise pros

"The initial setup of Nagios Log Server was easy and straightforward."

"The product is scalable."

"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."

"A great feature of the solution involves its internal portal."

"One of the most valuable features is the dashboard because the UI was effective and easy to use."

"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."

Cons

"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."

"There are many other applications in the market that influenced my rating reduction."

"The problem was with the complexity and the cost to add extensions."

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

"More customization is always useful."

"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."

"The support from the Graylog community is helpful, but they can do better."

"The documentation for Graylog Enterprise can be improved, as this has been a pain point."

More Graylog Enterprise cons

"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."

"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."

"The support could be better."

"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 support could be better. They only offer email support."

Pricing and Cost Advice

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

"If you want something that works and do not have the money for Splunk or QRadar, take 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."

"I use the free version of Graylog."

"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."

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

"We're using the Community edition."

More Graylog Enterprise pricing and cost advice

"We found the pricing to be quite affordable."

"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."

"For a single instance, the price is around $4,000."
