It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers.
Manager Director at Earth
This can lead to alerts that are collections of disjointed signals that sometimes make no sense and lack real context; this simplistic approach makes it hard to find coherent stories during investigations.
CSO at Altera
The correlation rules and log mapping are not as mature compared to other SIM tools like Splunk.
SOC Analyst at a computer software company with 1,001-5,000 employees

Featured Reviews

reviewer2350791 - PeerSpot reviewer
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.
SC
CSO at Altera
Has improved implementation speed and coverage but lacks contextual accuracy in alerts
One major improvement I would suggest for Sumo Logic Security is in its risk-based alerting system; while it initially sounds clever and modern, it works as a point-based system where an IP address or entity gets points for bad actions, raising alerts when enough points are collected. This can lead to alerts that are collections of disjointed signals that sometimes make no sense and lack real context; this simplistic approach makes it hard to find coherent stories during investigations. To improve in the support area, I recommend enhancing the technical part because, while the process is good, the actual quality may depend on the personnel involved.
