Security Officer at JSC "Moldtelecom" S.A.
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.

It consolidates all logs into one place and provides required features and functionalities
Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to do RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Real-time UDP/GELF logging and full text-based searching."
"The product is scalable. The solution is stable."
"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."
"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."
"I am very proud of how very stable the solution is."
"Graylog Enterprise as a SIEM is fantastic for receiving logs, and the integrations with external connectors also add many features."
"Collaboration between teams has improved because we can share the ID of a specific log with the support team, infrastructure team, architecture team, or development team, allowing everyone to handle the same information and have access to the same environment."
"I like the correlation and the alerting."
"The solution aggregates all event streams, so that if there are any issues, it's all in the same interface."
"LogDNA consolidates all logs into one place, which is super valuable."
"We haven't had anything yet that we couldn't do through LogDNA."
"With LogDNA, which brings all the logs together in an interleaved stream, it allows us to take a transaction and relate it to other contextual events making the gathering of evidence for auditors and our internal RCA much more productive."
 

Cons

"The area in Graylog that needs to be improved or enhanced would be the integrations."
"The initial setup was really complex because I did it myself."
"I would rate them as a two out of 10. You are on your own without an enterprise license."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"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-"
"I believe that Graylog Enterprise could be improved. One of the negative points is that it could be more intuitive, especially for someone who is just starting to use it; depending on the amount of logs and the complexity of the query, the analysis may require a bit more technical knowledge."
"Graylog Enterprise is a fantastic tool, but for small and medium-sized businesses the cost ends up being high, especially in the Brazilian and Latin American market."
"Lacks sufficient documentation."
"Scalability could be improved; we are using it through the IBM cloud deployment and on some of the data centers that are very heavily used, there is a significant lag in the event stream, sometimes 10, 15 minutes behind, which makes the RCA impossible."
"No ability to encapsulate a query or a filter, and communicate or share that among the team."
"Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue."
 

Pricing and Cost Advice

"We're using the Community edition."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"It's an open-source solution that can be used free of charge."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"I use the free version of Graylog."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"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."
"We are using the free version of the product. However, the paid version is expensive."
