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

"The tool can be used in multi-cluster environments."
"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 product's most valuable features are ease of installation, management, and reporting. It has an efficient ability to set thresholds for alerts, as well."
"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"We are using Grafana Loki as a database for real-time metrics."
"The solution's most valuable feature is its new interface."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"I am very proud of how very stable the solution is."
"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."
"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."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
 

Cons

"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"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."
"I do not see any areas for improvement at the moment."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"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."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"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."
"With technical support, you are on your own without an enterprise license."
"Lacks sufficient documentation."
"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."
"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."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
