Virtual Server Monitoring ######################### The monitoring graphs show the current and historic utilization of virtual server's resources from the perspective of the compute node. =============================== ================ :ref:`Access Permissions ` ------------------------------- ---------------- *SuperAdmin* read-only *DCAdmin* read-only *VmOwner* read-only =============================== ================ CPU Graphs ========== * **CPU usage** - Total compute node CPU consumed by the virtual machine. .. image:: img/monitoring_cpu_usage.png * **CPU wait time** - Total amount of time spent in CPU run queue by the virtual machine. .. image:: img/monitoring_cpu_wait_time.png * **CPU load** - One-minute load average. .. image:: img/monitoring_cpu_load.png Memory Graphs ============= * **Memory usage** - Total compute node physical memory consumed by the virtual machine. .. image:: img/monitoring_memory_usage.png * **Swap usage** - Total compute node swap space used by the virtual machine. .. image:: img/monitoring_swap_usage.png NIC Graphs ========== * **NIC bandwidth** - The amount of received and sent network traffic through the virtual network interface. .. image:: img/monitoring_nic_bandwidth.png * **NIC packets** - The amount of received and sent packets through the virtual network interface. .. image:: img/monitoring_nic_packets.png Disk Graphs =========== * **Disk throughput** - The amount of written and read data on the virtual hard drive. .. image:: img/monitoring_disk_throughput.png * **Disk I/O** - The amount of write and read I/O operations performed on the virtual hard drive. .. image:: img/monitoring_disk_io.png Aggregated Disk Layer Graphs ============================ * **VM disk logical throughput** - Aggregated disk throughput on the logical layer (with acceleration mechanisms included). .. image:: img/monitoring_vm_disk_logical_io.png * **VM disk logical I/O** - Aggregated amount or read and write I/O operations on the logical layer (with acceleration mechanisms included). .. image:: img/monitoring_vm_disk_logical_throughput.png * **VM disk physical throughput** - Aggregated disk throughput on the physical (disk) layer. .. image:: img/monitoring_vm_disk_operations.png * **VM disk physical I/O** - Aggregated amount of read and write I/O operations on the physical (disk) layer. .. image:: img/monitoring_vm_disk_physical_io.png * **VM disk I/O operations by latency** - Aggregated amount of disk I/O operations by latency on the logical layer (with acceleration mechanisms included). .. image:: img/monitoring_vm_disk_physical_throughput.png
