Offers cost-effective log management with strong correlation features across observability tools
Grafana Loki's open-source capability is a significant benefit. Grafana has invested in making their enterprise tools competitive with other APM tools, facilitating cross-correlation with Mimir and Tempo for metrics and tracing. The tool offers good search functionality, and its on-premises capability is advantageous. The indexing performance is strong, making it a robust log management tool. Grafana Loki is notably cost-effective.

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.

Quotes from Members

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

Pros

"The most valuable feature of the solution is the tool's GUI. The solution's GUI is very user-friendly."
"The tool can be used in multi-cluster environments."
"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"The log collection feature is good and the solution is easily understandable. v"
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"Grafana Loki's open-source capability is a significant benefit, and Grafana has invested in making their enterprise tools competitive with other APM tools, facilitating cross-correlation with Mimir and Tempo for metrics and tracing."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
"Open source and user friendly."
"I like the correlation and the alerting."
"Message forwarding through the in-built module."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"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."
"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."
 

Cons

"We had a well-structured dashboard with a functional query. However, an issue arose when the Kubernetes pod restarted. The statistics from our Grafana query would reset, dropping to zero and starting anew. This was particularly noticeable with linear graphs, which are expected to show consistent growth."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"My main concern is the recommended production-grade setup. They suggest using tools like Tanka or Jsonnet. They should simplify the process to increase adoption."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"The solution's scalability depends on the team managing the Grafana instance."
"The Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"Graylog can improve the index rotation as it's quite a complex solution."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"There should be some user groups and an auto sign-in feature.​"
"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 documentation for Graylog Enterprise can be improved, as this has been a pain point."
 

Pricing and Cost Advice

"Grafana Loki is an open-source solution."
"My company doesn't need to pay for the licensing cost of the solution."
"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"The cost is less than other paid services like CloudWatch."
"Grafana Loki is a free, open-source solution."
"I find the licensing structure quite reasonable, as the free license effectively meets my requirements."
"I use the open-source version of the product."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"It's an open-source solution that can be used free of charge."
"We are using the free version of the product. However, the paid version is expensive."
"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.​​"
"I use the free version of Graylog."
"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.​"
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
