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 best feature of Grafana Loki is that it integrates well with our other tool."
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"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."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"The tool can be used in multi-cluster environments."
"Grafana Loki is easy to monitor and detect errors."
"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"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."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"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."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"The solution's most valuable feature is its new interface."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
 

Cons

"The platform's stability needs improvement."
"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."
"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."
"In Grafana Loki, the creation of metrics is not so easy, making it an area that could be made easier."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"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."
"More customization is always useful."
"There are many other applications in the market that influenced my rating reduction."
"With technical support, you are on your own without an enterprise license."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"The documentation for Graylog Enterprise can be improved, as this has been a pain point."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"There should be some user groups and an auto sign-in feature.​"
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."

"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."
