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.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

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

"With Graylog Enterprise, monitoring improved by up to 80 percent because of having all the logs centralized."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"I know that there are other similar tools available, but I enjoy using Graylog the most."
"I am very proud of how very stable the solution is."
"Real-time UDP/GELF logging and full text-based searching."
"The product is scalable. The solution is stable."
"I like the correlation and the alerting."
"Everything stands out as valuable, including the fact that I can quantify and qualify the logs, create pipelines and process the logs in any way I like, and create charts or data maps."
"I haven't had the chance to properly sink my teeth into Enterprise Security but so far I like that they added the MITRE ATT&CK features."
"The user interface is excellent, and since I'm using Splunk as a power user, it's easy to create dashboards."
"The solution has proven to be quite stable."
"It gave management confidence in current operations."
"On average, my security ops team takes fairly quickly to remediate security incidents with Splunk Enterprise Security, depending on the use case, minutes versus hours, compared to my previous solution, which was ArcSight."
"Manually, it used to take us a whole day to do strong monitoring, now it takes a maximum of two hours because of this product."
"The features I find most valuable in Splunk Enterprise Security are Incident Review, Security Essentials, Asset and Identity Management, and Machine Learning Toolkit."
"Splunk Enterprise Security definitely improved our operations."
"However, Log Insight is quite good and very useful."
"The most valuable features are log centralization and long-term retention for logs."
"The tool helps my company deal with security and log analysis, which are very important areas for us...It is a scalable solution."
"I believe it is a very useful solution if you have a large environment and C4 vCenter, or if you have thousands of virtual machines in your environment."
"Log Insight seems to be better than other solutions in terms of very good integrations and working out items to be able to log."
"The most valuable feature is server virtualization. It's been very useful."
"The system's management and its alerts are the most valuable aspects of the solution."
"The most valuable feature is server virtualization, it's been very useful."
 

Cons

"The technical support is a weak point in this product. It's not so easy to contact them and they don't answer immediately."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"I would like to see some kind of visualization included in Graylog."
"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."
"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."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"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."
"There is improvement needed when importing from some types of data sources."
"There are a lot of competitive products that are doing better than what Splunk is doing on the analytics side."
"Splunk is more expensive than other solutions."
"The solution could improve by giving more email details."
"Having analysts put their notes directly within the investigation feature in the incident review would be beneficial."
"The GUI should be improved, in other words, the overall appearance."
"One main change I would suggest is related to the incident board: when an incident is resolved, it should not appear on the incident board. It's just a rare occurrence that we open up the incident."
"The historical data extraction needs improvement. I would like the capability of taking data and having it trend longer."
"Integration with other vendors is something that could be improved, they could add more vendors."
"I don't use the solution on a day to day basis, so I'm not sure what specifically can be improved."
"The pricing of the solution could be improved."
"The monitoring landscape is getting bigger. When it comes to infrastructure monitoring, we need more visibility. VMware needs to integrate more related applications and third-party products. That would make it more appealing to an audience beyond the VMware team."
"If data migration occurs during a search, it alters performance, causing delays."
"My experience, however, is that Log Insight is not user friendly."
"The tool could be cheaper."
"VMware Aria Operations for Logs is not a cost-effective tool. Additionally, it is expensive, especially given the current economic conditions in Turkey."
 

Pricing and Cost Advice

"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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."
"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."
"We're using the Community edition."
"It's an open-source solution that can be used free of charge."
"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."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"Splunk Enterprise Security is not at all cost-friendly to be deployed in very small enterprises like start-ups."
"Splunk Enterprise Security is affordable."
"The pricing modules could be improved."
"I believe that Splunk Enterprise Security is worth the price, but it is expensive."
"I believe there is room for improvement in reducing costs, particularly in the financial aspect, as Splunk tends to be pricier compared to other options."
"The pricing model is expensive and a nightmare based on the amount of data."
"The tool's licensing is good and we haven't received any complaints from the team handling it."
"In terms of pricing, I believe Splunk is unreasonably costly for the majority of mid and small-sized companies."
"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."
"Pricing is good because it is part of the suite package. It comes in a bundle for us."
"I am not sure what the exact cost is. However, I believe the vRealize suite costs $2,500.00 per year."
"The pricing has been updated recently."
"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."
"I think it is a reasonably priced product."
"It is not cheap. But it is worth it."
