Regional Associate & Engineer at a outsourcing company with 1,001-5,000 employees
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.
Merit Ronald - PeerSpot reviewer
Senior Software Engineer at Absa Bank Uganda
Centralized log insights have reduced investigation time and improve security response
One improvement I want to see in Graylog Enterprise is artificial intelligence to help us automatically identify unusual patterns and suggest possible causes. I also want to see more ready-made dashboards and alert templates for common security use cases to help us gain value from the platform faster after deployment. Lastly, I want to see improvements in handling very large volumes of data, especially after searching, and a more user-friendly log management system, particularly in large environments. I give Graylog Enterprise a 9 out of 10 because it has a limitation of a steep learning curve for new users due to the many configuration options. It takes considerable time to become comfortable with creating searches, dashboards, and alerts. Additionally, in very large environments with large volumes of logs, it requires careful planning, and its data retention is quite limited.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The tool can be used in multi-cluster environments."
"There are new features like that pilot code and things like that for profiling."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"The best feature of Grafana Loki is that it integrates well with our other tool."
"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."
"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."
"Graylog is worth the given effort."
"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."
"I am very proud of how very stable the solution is."
"Real-time UDP/GELF logging and full text-based searching."
"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."
"I know that there are other similar tools available, but I enjoy using Graylog the most."
"I would consider myself Graylog2's number one fan or at least a big advocate of the utility of this product."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
 

Cons

"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 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."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"The platform's stability needs improvement."
"The Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"The product must improve its UI."
"The support from the Graylog community is helpful, but they can do better."
"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."
"There are many other applications in the market that influenced my rating reduction."
"There should be some user groups and an auto sign-in feature.​"
"The documentation for Graylog Enterprise can be improved, as this has been a pain point."
"Graylog can improve the index rotation as it's quite a complex solution."
"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 default dashboard widget that shows the topology of the clusters defined for the graylog install."
 

Pricing and Cost Advice

"The pricing structure varies based on the number of users; there might be specific taxes to pay for it."
"The solution is open source."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
"My company doesn't need to pay for the licensing cost of the solution."
"Grafana Loki is an open-source solution."
"The cost is less than other paid services like CloudWatch."
"I use the open-source version of the product."
"We use a free version."
"It's an open-source solution that can be used free of charge."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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.​​"
"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."
"It's open source and free. They have a paid version, but we never looked into that because we never needed the features of the paid version."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"I use the free version of Graylog."
