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

"Troubleshooting is straightforward with Graylog Enterprise."

"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."

"The product does all the things it must do very well."

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

"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."

"The Graylog features that have proven to be most beneficial for our data analysis in particular are that we tend to use it as a big data store, so we have the correlation rules that, if something matches under certain conditions, it raises an alarm."

"The ability to write custom alerts is key to information security and compliance."

"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."

More Graylog Enterprise pros

"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 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."

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

Cons

"The area in Graylog that needs to be improved or enhanced would be the integrations."

"I would rate them as a two out of 10. You are on your own without an enterprise license."

"The technical support is a weak point in this product. It's not so easy to contact them and they don't answer immediately."

"If you have a whole team trying to fix the Graylog instance for two days, that's a bit too much."

"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."

"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."

"Graylog can improve the index rotation as it's quite a complex solution."

"More customization is always useful."

More Graylog Enterprise cons

"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."

"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 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."

Pricing and Cost Advice

"Having paid official support is wise for projects."

"We're using the Community edition."

"We are using the free version of the product. However, the paid version is expensive."

"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."

"It's an open-source solution that can be used free of charge."

"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."

"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."

More Graylog Enterprise pricing and cost advice

"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."

"We found the pricing to be quite affordable."
