RHV / oVirt / OLVM Monitoring

Implementation is agent less.
Data source is ovirt_engine_history database which is part of Data Warehouse on oVirt/RHV (RHV, formerly RHEV) Virtualization Manager.
Tool accesses the ovirt_engine_history database remotely via its SQL API.

Monitored components

  • Cluster
  • Host
  • VM
  • Storage Domain

Monitored metrics

  • CPU
  • Memory utilization
  • LAN throughput MB/sec
  • Storage space GB
  • 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
Filesystem usage Usage in %, GB
Error log errpt
LVM filesystem, VG, LV, disk, storage, volume
Disk multipath disk
