Professional
Bleemeo monitors ESXi hosts with real-time CPU, memory, swap, disk I/O, and network metrics, plus the number of running and stopped VMs on each host. Hosts are automatically discovered from vCenter or standalone ESXi connections.
Metrics
Section titled “Metrics”| Metric | Description |
|---|---|
cpu_used | Percentage of CPU capacity being used by the host |
mem_total | Total memory available on the host, including reservation for powered-on VMs |
mem_used_perc | Percentage of memory being used by the host |
swap_in | Rate of memory being swapped in by the host |
swap_out | Rate of memory being swapped out by the host |
io_read_bytes | Rate of data read from disk by the host |
io_write_bytes | Rate of data written to disk by the host |
net_bits_sent | Rate of data transmitted by the host |
net_bits_recv | Rate of data received by the host |
vms_running_count | Number of VMs currently running on the host |
vms_stopped_count | Number of VMs currently stopped on the host |
Disk I/O and network metrics have an item label identifying the specific datastore, disk, or network interface.
