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.

Pros

"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 most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"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."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"The product's most valuable features are ease of installation, management, and reporting. It has an efficient ability to set thresholds for alerts, as well."
"Loki also utilizes the same service discovery mechanism as used by Prometheus. So, whatever labeled metadata you see in Prometheus, you have the exact same metadata in the Loki system. Given this level of intricacy and the attempt to address these challenges, I firmly believe that Loki deserves praise for the work."
"There are new features like that pilot code and things like that for profiling."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"Message forwarding through the in-built module."
"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."
"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."
"Real-time UDP/GELF logging and full text-based searching."
"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
"I am very proud of how very stable the solution is."
 

Cons

"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."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"In Grafana Loki, the creation of metrics is not so easy, making it an area that could be made easier."
"I would rate Grafana Loki a seven out of ten because it is open source, and sometimes there can be problems that are difficult to fix without official support."
"The solution's scalability depends on the team managing the Grafana instance."
"I do not see any areas for improvement at the moment."
"The product must improve its UI."
"We face some bugs when we install the latest version of Grafana Loki."
"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."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"There are many other applications in the market that influenced my rating reduction."
"The problem was with the complexity and the cost to add extensions."
"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."
"We ran into problems with Elasticsearch throwing a circuit-breaking exception due to field data size being too large. It turned out that the heap size directly impacted this size in a high-throughput environment, causing unexplained instability in Graylog. We were able to troubleshoot on the Elasticsearch size, but we should have been able to reference some minimum requirements for Graylog to know that our settings weren't sufficient."
"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."
