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.

Real-time monitoring and analytics are very easy and fast and very easy to use
The alerting and real-time analytics helped the security team. They are using a Hadoop database, so real-time monitoring and analytics are very easy and fast. Queries return results quickly and in very small time. It has full automation and automated SIEM responses. We are currently only testing Logsign, but in a few months, we plan to integrate our servers, routers, firewalls, and endpoints into our company's Logsign instance. Then, we can manage everything using Logsign.

Cons

"We face some bugs when we install the latest version of Grafana Loki."
"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."
"The platform's stability needs improvement."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"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."
"I do not see any areas for improvement at the moment."
"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's scalability depends on the team managing the Grafana instance."
"I hope they address the pricing model for Logsign Next-Gen SIEM, especially regarding regional variations. The pricing should not differ based on the country of operation as it can lead to dissatisfaction among customers. A fixed pricing structure would be more favorable for us. I would also suggest enhancing the GUI interface and adding features similar to xFi Exchange from IBM Pure. This would streamline operations and save time for analysts."
"AI and machine learning need to be developed. If they develop those features, I think everything will be fine."
"Improvements needed in Logsign SIEM are providing specific security alerts that can be filtered and configured more effectively."
