VMware vSphere VM Monitoring

Starter

Professional

Bleemeo monitors virtual machines with CPU, memory, swap, disk I/O, network, and guest filesystem usage metrics. VMs are automatically discovered from vCenter or standalone ESXi connections.

Note

VM monitoring can be disabled with the skip_monitor_vms configuration option if you only need host and cluster-level visibility. See Configuration for details.

Metrics

Metric	Description
cpu_used	CPU usage by the VM, as a percentage of allocated vCPU capacity
vsphere_vm_cpu_latency_perc	Percentage of time the VM is waiting for CPU to become available
mem_used_perc	Percentage of allocated memory actively used by the VM
swap_used	Amount of swapped memory of the VM
io_read_bytes	Rate of data read from disk by the VM
io_write_bytes	Rate of data written to disk by the VM
net_bits_sent	Rate of data transmitted by the VM
net_bits_recv	Rate of data received by the VM
disk_used_perc	Guest filesystem space used as a percentage

Disk I/O and network metrics have an item label identifying the specific disk or network interface. The disk_used_perc metric has an item label with the filesystem mount path (e.g., /, /var).

Labels

Each VM metric includes the following labels:

Label	Description	Example
dcname	Datacenter name	DC-Paris
clustername	Cluster name (empty for standalone ESXi hosts)	Production-Cluster
esxhostname	ESXi host running this VM	esxi-01.example.com
vmname	Virtual machine name	web-server-01
item	Specific disk, network interface, or filesystem path (only on I/O, network, and disk usage metrics)	scsi0:0, ethernet0, /
