vSphere monitoring

Glouton can retrieve facts and metrics of hosts and VMs, using the API exposed by vCenters and ESXIs.

Configuration

To enable vSphere monitoring, you need to add the following section to your Bleemeo agent configuration:

vsphere:
  - url: "https://<vcenter-url>/sdk"
    username: "<username>"
    password: "<password>"
    insecure_skip_verify: false
    skip_monitor_vms: false

Note that you can add multiple vCenter appliances.

Metrics

Host

Metric name	Description
cpu_used	Percentage of CPU capacity being used by the host
mem_total	Total reservation, available and consumed, for powered-on VMs on the host
mem_used_perc	Percentage of memory being used by the host
swap_in	Amount of memory swapped in by the host
swap_out	Amount of memory swapped out by the host
io_read_bytes	Amount of data read from the disk by the host
io_write_bytes	Amount of data written to the disk by the host
net_bits_sent	Average rate at which data was transmitted by the host
net_bits_recv	Average rate at which data was received by the host
vms_running_count	Count of VM(s) currently running on the host
vms_stopped_count	Count of VM(s) currently stopped on the host

VM

Metric name	Description
cpu_used	CPU utilization by the VM
vsphere_vm_cpu_latency_perc	Percent of the time the VM is waiting for CPU to be available
mem_used_perc	Percent of the memory used by the VM
swap_used	Amount of swapped memory of the VM
io_read_bytes	Amount read from the disk by the VM
io_write_bytes	Amount written to the disk by the VM
net_bits_sent	Data transmission rate of the VM
net_bits_recv	Data reception rate of the VM
disk_used_perc	Filesystem space used in percent

Labels

VSphere metrics have the following labels:

• dcname
• clustername (Not for standalone ESXIs)
• esxhostname (Only for hosts and VMs)
• vmname (Only for VMs)

Additionally, metrics related to datastore, network or disk have an item label, which whether represents:

• a specific datastore
• a network interface
• a disk
• a partition
