The Domotz Collector has been benchmarked on a virtual machine configured with 2 vCPUs and 4 GB of RAM.
This article outlines the minimum hardware requirements and provides guidance on when to scale up resources.
Minimum Configuration: 2 vCPUs / 4 GB RAM
- This setup supports the following:
- Up to 1,000 discovered devices
- Up to 100 External Hosts
- Up to 15 Routed Networks (/24)
- Up to 300 Managed Devices in total
- With an average of 10 SNMP metrics monitored per device
- And up to 100 scripts applied overall
This configuration ensures stable operation, even with discovery protocols enabled.
Note:
If the virtual machine also runs other services in addition to the Domotz Collector, consider increasing CPU and RAM resources accordingly.
When to Increase Resources
If your deployment involves monitoring larger environments than described above, we recommend upgrading to at least 4 vCPUs and 8 GB of RAM (or higher) to maintain stability and responsiveness.
Additional Recommendations:
- Avoid exceeding 2,500 discovered devices per collector.
- Monitoring more than 200 External Hosts per collector is not recommended.
- Monitoring more than 20 Routed Networks per collector is not
- recommended.
- For environments requiring low discovery latency (e.g., sub-minute detection of state changes), additional resources may be necessary.
If you expect to reach any of these limits, please contact Domotz Support to discuss suitable options — or consider deploying multiple collectors for optimal performance.
