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

"Troubleshooting is straightforward with Graylog Enterprise."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"The product is scalable. The solution is stable."
"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."
"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."
"The solution's most valuable feature is its new interface."
"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."
"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 simplicity, flexibility, and extensibility are valuable features as we can integrate everything in vRealize."
"The setup and installation are very easy."
"One of the things I like about it is its interface. When it comes to generating reports on VMs and stuff, it's very quick. This is very handy for the technical team, who need to generate reports quickly. So that's really good."
"The most valuable features are log centralization and long-term retention for logs."
"What I like is that you can have different storage locations for different applications."
"We use the on-premises version of this solution for log analysis and to find details about certain issues."
"The virtualization solution supports data center virtualization, network and security."
"The ability to narrow into a specific time to filter heavy hitters and anomalies is extremely valuable."
 

Cons

"More customization is always useful."
"Graylog can improve the index rotation as it's quite a complex solution."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"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."
"With technical support, 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."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"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."
"In the VMware environment, one area for improvement is the handling of VM failovers due to host failures, such as unexpected shutdowns from hardware issues. Currently, High Availability (HA) doesn't seem to recognize whether the VMs are online during failover, treating them as offline or unavailable."
"The tool could be cheaper."
"Paid or free does not matter, but it is complex to find good training material for vRealize Log Insight."
"Technical support should be improved."
"It needs better integration with third-party analytics tools."
"I don't use the solution on a day to day basis, so I'm not sure what specifically can be improved."
"What I'd like to improve in vRealize Log Insight is the licensing model. VMware provides vRealize Log Insight along with the VMware Cloud Foundation, but customers who would like to go for the native VMware would have to procure vRealize Log Insight separately. Today, vRealize Log Insight is offered on two different licenses, one is based on the number of VMs, and the other is based on the number of physical codes on the machine. If VMware can provide a bundle offer for customers who procure more than ten licenses, where you can have an option to run, for example, three hundred machines on vRealize Log Insight with no extra cost, this would encourage more people to adopt the solution. What I'd like to see in the next release of vRealize Log Insight is for a cloud option to be available, which would be a pay-as-you-go licensing model that would allow me to pick and choose what I'll monitor. For example, I have one thousand and three hundred critical servers, and the seven hundred servers for basic development, I don't want to monitor on vRealize Log Insight today, so I should be able to pick what I need to monitor on the solution and only pay for that specific instance. If VMware can apply these changes, it would help VMware customers to procure more or adopt more of vRealize Log Insight even in smaller projects."
"The tool does not provide a centralized pane for monitoring."
 

Pricing and Cost Advice

"I use the free version of Graylog."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"Having paid official support is wise for projects."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"We're using the Community edition."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"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 product's price is reasonable, but when it comes to SQL licensing, it's a bit expensive."
"Pricing could always be lower. If it were free, I would be more satisfied."
"I rate the product's price a six on a scale of one to ten, where one is cheap, and ten is expensive."
"I think it is a reasonably priced product."
"Pricing is good because it is part of the suite package. It comes in a bundle for us."
"The pricing has been updated recently."
"The license cost for any other monitoring tool is too high compared to this product."
