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

"It is easier to find some issues, and if I find some issues, then it is easier to resolve them."

"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."

"Feature-wise or from the end user perspective, Graylog is just great."

"Open source and user friendly."

"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."

"Real-time UDP/GELF logging and full text-based searching."

"This had increased productivity for the dev and support teams, because we are directly notifying them."

"What I like about Graylog is that it's real-time and you have access to the raw data. So, you ingest it, and you have access to every message and every data item you ingest. You can then build analytics on top of that. You can look at the raw data, and you can do some volumetric estimations, such as how big traffic you have, how many messages of data of a type you have, etc."

More Graylog Enterprise pros

"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."

"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

"The initial setup was really complex because I did it myself."

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

"The problem was with the complexity and the cost to add extensions."

"The alerting system could be more flexible."

"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"

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

"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."

"There are many other applications in the market that influenced my rating reduction."

More Graylog Enterprise cons

"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."

"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 customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."

Pricing and Cost Advice

"Consider Enterprise support if you have atypical needs or setup requirements."

"I use the free version of Graylog."

"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."

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

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

"We're using the Community edition."

"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

"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."

"For a single instance, the price is around $4,000."

"We found the pricing to be quite affordable."
