XenServer Monitoring
Implementation is agent less, data sources:
- Performance data: XCP RRD
- Xen API commands via SSH
Monitored components
- Host
- Pool
- VM
- Storage
Monitored metrics
- CPU
- Memory utilization
- LAN throughput MB/sec
- Storage throughput MB/sec
- Storage throughput IOPS
- Storage latency

Collected data set can be enhanced about OS agent which brings these additional metrics:
| OS CPU | CPU sys, user, IO wait |
| CPU queue | Load avrg, Blocked processes |
| JOB | CPU, Memory |
| Memory utilization | Used, FS cache |
| LAN (ethernet adapters) | MB/sec, packet count |
| SAN (FC,vSCSI adapters) | MB/sec, packets/sec, Latency |
| Paging space utilization | Usage in % |
| Paging rate | MB/sec |
