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.

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.

Pros

"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."
"The most valuable part of Loki is the ability to filter logs by keywords and devices."
"We are using Grafana Loki as a database for real-time metrics."
"The most valuable feature of Grafana Loki is the dashboards which are really simple to create."
"The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"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."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"With Graylog Enterprise, monitoring improved by up to 80 percent because of having all the logs centralized."
"I am very proud of how very stable the solution is."
"It is easier to find some issues, and if I find some issues, then it is easier to resolve them."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"The solution's most valuable feature is its new interface."
"I would consider myself Graylog2's number one fan or at least a big advocate of the utility of this product."
"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
 

Cons

"The correlation of requests is not simple in Grafana Loki and can be improved."
"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."
"It's not intended for proprietary services, so you have to struggle with configuration a lot."
"The platform's stability needs improvement."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"The Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"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."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"Dashboards, stream alerts and parsing could be improved."
"I would like to see some kind of visualization included in Graylog. The report is plain, they could be improved."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"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."
"The alerting system could be more flexible."
"We ran into problems with Elasticsearch throwing a circuit-breaking exception due to field data size being too large. It turned out that the heap size directly impacted this size in a high-throughput environment, causing unexplained instability in Graylog. We were able to troubleshoot on the Elasticsearch size, but we should have been able to reference some minimum requirements for Graylog to know that our settings weren't sufficient."
"Its scalability gets complicated when we have to update or edit multiple nodes."
