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 product's most valuable features are ease of installation, management, and reporting. It has an efficient ability to set thresholds for alerts, as well."
"There are new features like that pilot code and things like that for profiling."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"We are using Grafana Loki as a database for real-time metrics."
"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 the solution is the tool's GUI. The solution's GUI is very user-friendly."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"Grafana Loki is easy to monitor and detect errors."
"Real-time UDP/GELF logging and full text-based searching."
"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."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"Graylog is very handy."
"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."
"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
 

Cons

"We encountered certain limitations when it came to alerting, particularly when dealing with specific data sources."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"We face some bugs when we install the latest version of Grafana Loki."
"The platform's stability needs improvement."
"We had a well-structured dashboard with a functional query. However, an issue arose when the Kubernetes pod restarted. The statistics from our Grafana query would reset, dropping to zero and starting anew. This was particularly noticeable with linear graphs, which are expected to show consistent growth."
"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."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"The solution's scalability depends on the team managing the Grafana instance."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"There should be some user groups and an auto sign-in feature.​"
"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 infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"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 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 can improve the index rotation as it's quite a complex solution."
 

Pricing and Cost Advice

"We use a free version."
"You can use the free version of Grafana Loki on-premises."
"My company doesn't need to pay for the licensing cost of the solution."
"Grafana Loki is an open-source solution."
"Grafana Loki is a free, open-source solution."
"I find the licensing structure quite reasonable, as the free license effectively meets my requirements."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"The cost is less than other paid services like CloudWatch."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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."
"Having paid official support is wise for projects."
"It's an open-source solution that can be used free of charge."
"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."
"We're using the Community edition."
"We are using the free version of the product. However, the paid version is expensive."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
