Question
Does Cribl Edge require 1 vCPU and 2 GB RAM per fleet on the Leader? For example, do eight Edge fleets require eight vCPUs and 16 GB RAM on the Leader as suggested in the Recommended Fleet Configuration doc?
Environment
- Cribl Cloud Managed Leader
- Multiple Cribl Edge Fleets
Answer
You do not need to allocate 1 vCPU and 2GB RAM on the Leader node for every Fleet when your Cribl Edge deployment is managing 10,000 or fewer Edge Nodes.
For deployments up to approximately 10,000 Edge Nodes, follow the standard Leader sizing recommendations from the Edge Deployment Planning and OS and System Requirements documentation. In this range, you do not need to resize the Leader just because you add more Fleets, as long as the Leader remains within the recommended baseline sizing and shows healthy CPU and memory utilization.
The guidance to “add 1 vCPU + 2GB of RAM per fleet” comes from the Plan Large-Scale Deployments of Cribl Edge documentation and is intended for large-scale deployments where a single Leader manages tens or hundreds of thousands of Edge Nodes.
If the deployment is expected to remain below 10,000 Edge Nodes, and the Leader is currently within standard sizing guidelines and operating with healthy headroom, you can safely continue using that configuration without applying the “1 vCPU + 2GB RAM per Fleet” rule.
Additional Information
- For standard deployments (up to 10,000 Edge Nodes), use the baseline Leader sizing and general deployment guidance in the Deployment Planning documentation for Cribl Edge.
- For larger deployments, refer to Plan Large-Scale Deployments of Cribl Edge for:
- Recommended Leader configuration based on total Edge Node count (for example, additional vCPU and RAM per 10,000 Nodes).
- Recommended Fleet configuration (1 vCPU and 2GB RAM per Fleet) in the context of managing up to 100,000–250,000 Nodes.
- Monitor Leader health (CPU, memory, and connection process utilization) over time; treat the large-scale guidance as a planning tool for growth, not as an immediate requirement for small or moderate Edge deployments.
