Featured Reviews

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

"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"Graylog Enterprise positively impacts the organization by helping the team and analysts investigate incidents faster since logs from servers, endpoints, cloud, and firewalls are available in one place."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"I know that there are other similar tools available, but I enjoy using Graylog the most."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"We run a containerized microservices environment, and 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."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"Troubleshooting is straightforward with Graylog Enterprise."
"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."
"The initial setup of Nagios Log Server was easy and straightforward."
"The product is scalable."
"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

"We ran into problems with Elasticsearch throwing a circuit-breaking exception due to field data size being too large. It turned out that the heap size directly impacted this size in a high-throughput environment, causing unexplained instability in Graylog. We were able to troubleshoot on the Elasticsearch size, but we should have been able to reference some minimum requirements for Graylog to know that our settings weren't sufficient."
"The initial setup was really complex because I did it myself."
"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."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"There should be some user groups and an auto sign-in feature.​"
"Dashboards, stream alerts and parsing could be improved."
"The documentation for Graylog Enterprise can be improved, as this has been a pain point."
"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 configurations during initial setup could be improved."
"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."
"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

"Having paid official support is wise for projects."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"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."
"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.​"
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"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 found the pricing to be quite affordable."
"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."
