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

"We are using Grafana Loki as a database for real-time metrics."
"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."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"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."
"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"The log collection feature is good and the solution is easily understandable. v"
"I am very proud of how very stable the solution is."
"Everything stands out as valuable, including the fact that I can quantify and qualify the logs, create pipelines and process the logs in any way I like, and create charts or data maps."
"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 is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
"I know that there are other similar tools available, but I enjoy using Graylog the most."
"The product is scalable. The solution is stable."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
 

Cons

"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."
"We encountered certain limitations when it came to alerting, particularly when dealing with specific data sources."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"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 correlation of requests is not simple in Grafana Loki and can be improved."
"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."
"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."
"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."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"There should be some user groups and an auto sign-in feature.​"
"I would rate them as a two out of 10. You are on your own without an enterprise license."
"For Python developers, it would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"There are many other applications in the market that influenced my rating reduction."
 

Pricing and Cost Advice

"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"The cost is less than other paid services like CloudWatch."
"Grafana Loki is an open-source solution."
"I find the licensing structure quite reasonable, as the free license effectively meets my requirements."
"My company doesn't need to pay for the licensing cost of the solution."
"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."
"I use the open-source version of the product."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"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."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"It's an open-source solution that can be used free of charge."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"We are using the free version of the product. However, the paid version is expensive."
