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

"Grafana Loki is easy to monitor and detect errors."
"The most valuable features of the solution stem from the fact that it is an open-source tool that is stable and flexible."
"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"The log collection feature is good and the solution is easily understandable. v"
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"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 part of Loki is the ability to filter logs by keywords and devices."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"The ability to write custom alerts is key to information security and compliance."
"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."
"Open source and user friendly."
"Troubleshooting is straightforward with Graylog Enterprise."
"Real-time UDP/GELF logging and full text-based searching."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"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."
"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

"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."
"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."
"The product must improve its UI."
"Visualization-wise, Grafana Loki's dashboard looks a little outdated compared to other open-source visualization tools like Chronograf."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"
"Elasticsearch recommendations for tuning could be better. Graylog doesn't have direct support for running the system inside of Kubernetes, so it can be challenging to fill in the gaps and set up containers in a way that is both performant and stable."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"There are many other applications in the market that influenced my rating reduction."
"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."
"With technical support, you are on your own without an enterprise license."
"There should be some user groups and an auto sign-in feature.​"
 

Pricing and Cost Advice

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