Featured Reviews

Merit Ronald - PeerSpot reviewer
Senior Software Engineer at Absa Bank Uganda
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

"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
"Graylog is very handy."
"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."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"It is easier to find some issues, and if I find some issues, then it is easier to resolve them."
"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 initial setup of Nagios Log Server was easy and straightforward."
"A great feature of the solution involves its internal portal."
"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."
 

Cons

"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 technical support is a weak point in this product. It's not so easy to contact them and they don't answer immediately."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"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."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"The documentation for Graylog Enterprise can be improved, as this has been a pain point."
"Dashboards, stream alerts and parsing could be improved."
"If you have a whole team trying to fix the Graylog instance for two days, that's a bit too much."
"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."
"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 support could be better. They only offer email support."
"The configurations during initial setup could be improved."
 

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."
"We're using the Community edition."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"Having paid official support is wise for projects."
"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."
"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."
"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."
