Featured Reviews

Merit Ronald - PeerSpot reviewer

Centralized log insights have reduced investigation time and improve security response
One improvement I want to see in Graylog Enterprise is artificial intelligence to help us automatically identify unusual patterns and suggest possible causes. I also want to see more ready-made dashboards and alert templates for common security use cases to help us gain value from the platform faster after deployment. Lastly, I want to see improvements in handling very large volumes of data, especially after searching, and a more user-friendly log management system, particularly in large environments. I give Graylog Enterprise a 9 out of 10 because it has a limitation of a steep learning curve for new users due to the many configuration options. It takes considerable time to become comfortable with creating searches, dashboards, and alerts. Additionally, in very large environments with large volumes of logs, it requires careful planning, and its data retention is quite limited.

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

"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"I like the correlation and the alerting."
"The product is scalable. The solution is stable."
"Troubleshooting is straightforward with Graylog Enterprise."
"The solution's most valuable feature is its new interface."
"Graylog is very handy."
"Open source and user friendly."
"The centralized logs where one can find bugs quicker and find the line of code that is a problem has made us more efficient."
"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. 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."
"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."
 

Cons

"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"Dashboards, stream alerts and parsing could be improved."
"There are many other applications in the market that influenced my rating reduction."
"The support from the Graylog community is helpful, but they can do better."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"The configurations during initial setup could be improved."
"The support could be better. They only offer email support."
"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."
 

Pricing and Cost Advice

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