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

"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"The most valuable part of Loki is the ability to filter logs by keywords and devices."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"Loki also utilizes the same service discovery mechanism as used by Prometheus. So, whatever labeled metadata you see in Prometheus, you have the exact same metadata in the Loki system. Given this level of intricacy and the attempt to address these challenges, I firmly believe that Loki deserves praise for the work."
"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"The tool can be used in multi-cluster environments."
"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."
"Open source and user friendly."
"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 run a containerized microservices environment, and 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."
"With Graylog Enterprise, monitoring improved by up to 80 percent because of having all the logs centralized."
"Graylog Enterprise positively impacts the organization by helping the team and analysts investigate incidents faster since logs from servers, endpoints, cloud, and firewalls are available in one place."
"The ability to write custom alerts is key to information security and compliance."
 

Cons

"I do not see any areas for improvement at the moment."
"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."
"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."
"The correlation of requests is not simple in Grafana Loki and can be improved."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"We face some bugs when we install the latest version of Grafana Loki."
"The Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"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. The report is plain, they could be improved."
"The problem was with the complexity and the cost to add extensions."
"Graylog Enterprise performs well overall; however, the UI could be improved because the SOC team creates multiple dashboards based on their use cases, and creating dashboards is complex."
"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."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"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."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
 

Pricing and Cost Advice

"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"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."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."
"We use a free version."
"Grafana Loki is an open-source solution."
"My company doesn't need to pay for the licensing cost of the solution."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"I use the free version of Graylog."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"Having paid official support is wise for projects."
"We're using the Community edition."
"We are using the free version of the product. However, the paid version is expensive."
"It's an open-source solution that can be used free of charge."
