Withdraw of the 6.9.2 Release
Unfortunately, due to critical issues identified with version 6.9.2, we have decided to remove it and ensure it's no longer available for download. These issues impacted the ability to install or upgrade but none were security-related. We are diligently working to resolve these issues and are planning to release an updated version 6.9.3 in early May.
What if you've already upgraded?For customers who have already upgraded to 6.9.2, no immediate action is required, as none of these issues are security-related. Once it's available, you will still be able to upgrade to 6.9.3 as normal. We appreciate your patience and trust as we continue to enhance our software to better serve you. Thank you for your understanding.
Hardware requirements
In this section, we describe the minimum and recommended hardware specifications for Opsview Monitor servers.
Recommendations Copied
The recommended hardware configuration is typically capable of monitoring approximately 300 hosts, but this may vary significantly depending on your monitoring configuration.
Orchestrator server Copied
- Four or more 64-bit CPUs (preferably multi-core)
- 8GB RAM
- 100GB available storage (with hardware RAID controller)
Collectors Copied
- 64-bit multi-core CPU
- 2GB RAM
- 40GB available storage, see Distributed Monitoring for more details on setting up Collectors.
Remote database Copied
- 4 or more CPU cores (64-bit)
- 16GB RAM
- 500GB available storage (with hardware RAID controller)
Minimum requirements Copied
The following guideline defines a few setups for different sizes, using AWS as a reference example for the machine flavors. Each host is assumed to have 20 service checks associated with intervals of 5 minutes. Keep in mind that these values are a minimum starting point and that we recommend choosing higher specs.

Opsview Monitor memory allocation Copied
In the table below, we describe the memory allocation for each section of the Opsview Monitor system. The memory allocations listed below are provided as guidance for most single-server deployments that monitoring approximately 300 devices.
Note
Actual requirements depends on the types and numbers of checks being performed on each device.
| System | Memory |
|---|---|
| OS | 512MB |
| MySQL | 512MB |
| Opsview daemons | 512MB |
| Opsview web | 1GB |
| Monitoring processes | 1GB |
| Opsview Reports Module | 1.5GB |
Achieving maximum scalability Copied
Please refer to Distributed Monitoring and Distributing Functionality.
Virtualized environments Copied
Opsview Monitor can run in a virtualized environment. In such an environment, disk I/O is the typical bottleneck, and so:
- Automatic snapshotting of guest Virtual Machines (VMs) causes significant I/O overhead and we would recommend that this feature is disabled or carefully managed outside of core production hours.
- An external storage array should be considered for large scale systems; for example, where thousands of hosts are monitored.
- The latest versions of hypervisor software should be installed, as well as the latest recommended drivers for storage and network operations.
