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

"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"
"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 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 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."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"The best feature of Grafana Loki is that it integrates well with our other tool."
"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."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"I am very proud of how very stable the solution is."
"It is easier to find some issues, and if I find some issues, then it is easier to resolve them."
"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"I like the correlation and the alerting."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
 

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."
"We face some bugs when we install the latest version of Grafana Loki."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"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 Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"The product must improve its UI."
"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."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"I would like to see some kind of visualization included in Graylog."
"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."
"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."
"There should be some user groups and an auto sign-in feature.​"
 

Pricing and Cost Advice

"The cost is less than other paid services like CloudWatch."
"The solution is open source."
"My company doesn't need to pay for the licensing cost of the solution."
"I find the licensing structure quite reasonable, as the free license effectively meets my requirements."
"You can use the free version of Grafana Loki on-premises."
"Grafana Loki is a free, open-source solution."
"We use a free version."
"I use the open-source version of the product."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"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."
"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."
"We're using the Community edition."
"It's an open-source solution that can be used free of charge."
"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.​​"
