Observational Issues on Virtual Machine:
- Unified Manager application is running slow.
- Unified Manager application CPU and/or memory utilization are extremely high. Swap/pagefile is in use.
- Unified Manager application experiences inconsistent behavior:
- Services hanging.
- Services restarting.
- Occasional issues with alert notifications.
- Inventory / performance acquisition polls may not complete within their normal 15 minute / 5 minute cycles.
- Other abnormal (unexplainable) inconsistent behavior when running in a virtual environment.
Observational Issues on the VMware ESXi Server:
- Memory Ballooning
- Transparent page sharing (disabled by default in ESXi 5.5 and above, but on by default in previous versions)
Any of the above memory management processes can (and usually do) have adverse effects to databases. Even if you are not experiencing ballooning or swapping, TPS or compression is likely to occur in the pool of memory that the application has available to it.
