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.

Improves infrastructure planning by helping us analyze network traffic
We use SevOne to collect and report on network flows SevOne improves infrastructure planning by helping us analyze network traffic. We can look at bandwidth for specific endpoints on the customer's network and analyze traffic to identify issues. For example, maybe some connectors are unavailable.…

Quotes from Members

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

Pros

"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
"Real-time UDP/GELF logging and full text-based searching."
"The product is scalable. The solution is stable."
"I like the simplicity of the solution, the fact that it's open source and user friendly."
"I know that there are other similar tools available, but I enjoy using Graylog the most."
"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."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"It is one of the most important systems we have in our environment for monitoring devices."
"SevOne provides us with continuous analytics of our network and that gives us an idea of the health of our network, where our weaknesses are, and what needs to be fixed."
"Flexible architecture: You can extend the system and its capacity by attaching another cluster pair."
"The modules and the performance management reports that come with data insights are two of the most valuable features. I also find the reports for Wi-Fi, Netflow, LAN, and WAN for monitoring to be very good."
"The reporting capabilities provided important metrics and data that helped in the oversight of our system, network, and overall IT infrastructure, both in terms of applications and hardware."
"In 90% of the cases, new devices are plug-and-play, so when a new version comes out then SevOne has support for it out of the box."
"It has been a godsend and has brought us 11 months of stability, the likes of which I'd never seen before in 15 years with the company."
"We find that the reporting is particularly valuable in terms of not only communicating with our peer teams but also with the executives."
 

Cons

"I would rate them as a two out of 10. You are on your own without an enterprise license."
"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."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"Dashboards, stream alerts and parsing could be improved."
"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."
"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."
"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 terms of having a complete view of our network performance, I would rate it a nine out of 10. The reason for not giving it a 10 is that there is no packet capture associated with SevOne, but we do have other tools in place to do that."
"Some of the services and functionality are adapted for SevOne via open-source, and the cost is very high. For the price that they are asking, it cannot be justified."
"I am impressed with their LAN side, WAN side on the Wi-Fi domains, but the SD WAN has room to improve."
"Their virtualization solution is not compatible with our Kubernetes environment, which is one of the reasons we are ending our relationship with them."
"NMS has several areas for improvement. It should be more user-friendly inside of NMS for some of the functionality in there. It's been getting better the last version or two, but the there have been bugs in there whenever I've gone to new versions."
"There is room for improvement in the integration with different vendors and the reporting capabilities."
"I would say that incorporating other technologies, we have great performance data, but if it started doing intelligence and looked at the patterns or correlations, that would be great."
"The GUI: both the dashboard/user view and the admin tool."
 

Pricing and Cost Advice

"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."
"It's an open-source solution that can be used free of charge."
"Having paid official support is wise for projects."
"We are using the free version of the product. However, the paid version is expensive."
"If you want something that works and do not have the money for Splunk or QRadar, take 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."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"There are different options available for licensing, with the per-device option being more expensive but more flexible."
"There are cheaper solutions available."
"A blocking point is the high upfront cost because it is challenging to get it accepted and the purchase approved."
"It is inexpensive compared to other monitoring tools."
"For the value that you get from SevOne, it's worth the price. There are a lot of cheaper alternatives on the market, and even free options. But they require more staff, more resources, and engineers with more advanced knowledge of monitoring. That's what makes SevOne worth the price."
"Choose a SevOne partner who can provide SevOne as a service and can deliver professional services and maintenance."
"Have a bank of licenses, because it is about the number of objects (RAM, ports, CPU, etc.)."
"The pricing has not evolved with the market, which is one of the reasons we are moving to a new product."
