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

"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"Open source and user friendly."
"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 solution's most valuable feature is its new interface."
"I like the simplicity of the solution, the fact that it's open source and user friendly."
"Graylog is very handy."
"The product is scalable. The solution is stable."
"With Graylog Enterprise, monitoring improved by up to 80 percent because of having all the logs centralized."
"The solution aggregates all event streams, so that if there are any issues, it's all in the same interface."
"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."
"LogDNA consolidates all logs into one place, which is super valuable."
"We haven't had anything yet that we couldn't do through LogDNA."
 

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 initial setup was really complex because I did it myself."
"For Python developers, it would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"Graylog can improve the index rotation as it's quite a complex solution."
"The problem was with the complexity and the cost to add extensions."
"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"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."
"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."
 

Pricing and Cost Advice

"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."
"I use the free version of Graylog."
"It's an open-source solution that can be used free of charge."
"We're using the Community edition."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"​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."
"Having paid official support is wise for projects."
