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, with strong indexing performance, cost-effectiveness, and the ability to cross-correlate with Mimir and Tempo for metrics and tracing, making it a robust log management tool."
"The most valuable feature of the solution is the tool's GUI. The solution's GUI is very user-friendly."
"The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"There are new features like that pilot code and things like that for profiling."
"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."
"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"The log collection feature is good and the solution is easily understandable. v"
"The ability to write custom alerts is key to information security and compliance."
"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."
"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."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"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."
"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."
"Message forwarding through the in-built module."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
 

Cons

"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."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"The solution's scalability depends on the team managing the Grafana instance."
"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."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"We face some bugs when we install the latest version of Grafana Loki."
"More customization is always useful."
"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."
"With technical support, you are on your own without an enterprise license."
"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."
"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"
"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"The problem was with the complexity and the cost to add extensions."
