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

"I would consider myself Graylog2's number one fan or at least a big advocate of the utility of this product."
"The ability to write custom alerts is key to information security and compliance."
"Graylog is very handy."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"I like the correlation and the alerting."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"This has increased productivity for the dev and support teams, because we are directly notifying them."
"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."
"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."
"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."
"The initial setup of Nagios Log Server was easy and straightforward."
"A great feature of the solution involves its internal portal."
"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."
 

Cons

"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."
"The alerting system could be more flexible."
"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."
"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."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"The problem was with the complexity and the cost to add extensions."
"The initial setup was really complex because I did it myself."
"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."
"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."
"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."
"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. They only offer email support."
"The configurations during initial setup could be improved."
 

Pricing and Cost Advice

"I use the free version of Graylog."
"Having paid official support is wise for projects."
"We are using the free version of the product. However, the paid version is expensive."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"We're using the Community edition."
"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."
"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 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."
"For a single instance, the price is around $4,000."
"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."
