The summary above is based on 18 interviews we conducted recently with Graylog and Grafana Loki users. To access the review's full transcripts, download our report.
"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."
"I appreciate the capability to process logs from microservices and seamlessly integrate them into Grafana."
"We are using Grafana Loki as a database for real-time metrics."
"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 the solution is the tool's GUI. The solution's GUI is very user-friendly."
"The tool can be used in multi-cluster environments."
"The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"The most valuable feature is the capability to set up alerts, which becomes necessary when we need to receive notifications for specific events."
"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."
"I like the correlation and the alerting."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"The ability to write custom alerts is key to information security and compliance."
"The solution's most valuable feature is its new interface."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"Message forwarding through the in-built module."
"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."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"The Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"We encountered certain limitations when it came to alerting, particularly when dealing with specific data sources."
"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."
"The solution's scalability depends on the team managing the Grafana instance."
"The correlation of requests is not simple in Grafana Loki and can be improved."
"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."
"Dashboards, stream alerts and parsing could be improved."
"More customization is always useful."
"Graylog can improve the index rotation as it's quite a complex solution."
"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."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"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."
"Lacks sufficient documentation."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
