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 best feature of Grafana Loki is that it integrates well with our other tool."
"There are new features like that pilot code and things like that for profiling."
"The log collection feature is good and the solution is easily understandable. v"
"We are using Grafana Loki as a database for real-time metrics."
"The most valuable feature of the solution is the tool's GUI. The solution's GUI is very user-friendly."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"Grafana Loki is easy to monitor and detect errors."
"The tool can be used in multi-cluster environments."
"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."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"We run a containerized microservices environment. Being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."
"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."
"It is easier to find some issues, and if I find some issues, then it is easier to resolve them."
"I like the correlation and the alerting."
"The solution's most valuable feature is its new interface."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
 

Cons

"We face some bugs when we install the latest version of Grafana Loki."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"There is a need for some change in the alerting types of the product. In short, a few changes in the alert area are needed due to minor shortcomings."
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"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."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"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."
"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 can improve the index rotation as it's quite a complex solution."
"More customization is always useful."
"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."
"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."
"Elasticsearch recommendations for tuning could be better. Graylog doesn't have direct support for running the system inside of Kubernetes, so it can be challenging to fill in the gaps and set up containers in a way that is both performant and stable."
 

Pricing and Cost Advice

"We use a free version."
"Grafana Loki is a free, open-source solution."

"Consider Enterprise support if you have atypical needs or setup requirements.​"

"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"It's an open-source solution that can be used free of charge."
"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."

"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"We're using the Community edition."
