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.

Dashboard personalization enhances troubleshooting capabilities
A valuable feature of VMware Aria Operations for Logs is its ability to allow personalization of dashboards and requests. This personalization capability is crucial because it helps tailor the tool to specific needs. It also has many effective features for log analysis, making it a competent tool despite not having a comprehensive comparison with other tools.

Quotes from Members

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

Pros

"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."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"I am very proud of how very stable the solution is."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"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 solution's most valuable feature is its new interface."
"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."
"It allows us to gain a comprehensive overview of our infrastructure."
"The setup and installation are very easy."
"What I like is that you can have different storage locations for different applications."
"The ability to narrow into a specific time to filter heavy hitters and anomalies is extremely valuable."
"The events are notably more descriptive, aiding in security and event analysis. We've also integrated Sky Collector, providing valuable insights and solutions for troubleshooting."
"The interface of the solution is good."
"The root cause analysis feature is very valuable."
"VMware Aria Operations for Logs is a very stable product."
 

Cons

"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"When it comes to configuring the processing pipeline, writing the rules can be very tedious, especially since the documentation isn't extensive on how the functions provided for these rules work."
"With technical support, you are on your own without an enterprise license."
"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"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."
"Lacks sufficient documentation."
"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."
"There are many other applications in the market that influenced my rating reduction."
"Customer service and support have declined. Six months ago, I would have rated it as an eight or nine. Currently, it feels more like a four, five, or six."
"The product's price falls on the higher end of the spectrum, making it an area of concern."
"Integration with other vendors is something that could be improved, they could add more vendors."
"I think that it should be able to integrate with other third-party backup and recovery solutions, more that it does now."
"From an improvement perspective, the tool needs to be made more user-friendly."
"The solution isn't user-friendly for admins."
"The tool could benefit from improved filter settings and dashboarding."
"The tool could be cheaper."
 

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."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"Having paid official support is wise for projects."
"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."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"We're using the Community edition."
"It's an open-source solution that can be used free of charge."
"I rate the product's price a six on a scale of one to ten, where one is cheap, and ten is expensive."
"The license cost for any other monitoring tool is too high compared to this product."
"It is not cheap. But it is worth it."
"The product's price is reasonable, but when it comes to SQL licensing, it's a bit expensive."
"I think it is a reasonably priced product."
"Pricing could always be lower. If it were free, I would be more satisfied."
"The licensing cost for vRealize Log Insight is a little higher, so in terms of cost, it all depends upon what kind of environment you have. If you have a complete virtualized environment, or at least you're using a ninety-five percent virtualized environment, then vRealize Log Insight will play a very good role because it is a VMware component, so it has very tight integration with other VMware components and systems. This means you don't have to procure any other monitoring and management tool, and you don't need a separate automation tool. vRealize Log Insight will have an upper hand if your environment is purely virtualized on VMware. If you're using a mix of physical and virtual components, for example, a 50:50 ratio, then you need to have a third-party component to manage overall monitoring."
"The pricing has been updated recently."
