this repo fork prometheus-libvirt-exporter
The libvirt api is here
This exporter makes use of libvirt-go, the digitalocean Go bindings for libvirt.
The following metrics/labels are being exported:
| Name | Description |
|---|---|
| up | scraping libvirt's metrics state |
| domains_number | get number of domains |
| domain_state_code | code of the domain state,include state description |
| maximum_memory_bytes | Maximum allowed memory of the domain, in bytes |
| memory_usage_bytes | Memory usage of the domain, in bytes |
| virtual_cpus | Number of virtual CPUs for the domain |
| cpu_time_seconds_total | Amount of CPU time used by the domain, in seconds |
| read_bytes_total | Number of bytes read from a block device, in bytes |
| read_requests_total | Number of read requests from a block device |
| write_bytes_total | Number of bytes written from a block device, in bytes |
| write_requests_total | Number of write requests from a block device |
| receive_bytes_total | Number of bytes received on a network interface, in bytes |
| receive_packets_total | Number of packets received on a network interface |
| receive_errors_total | Number of packet receive errors on a network interface |
| receive_drops_total | Number of packet receive drops on a network interface |
| transmit_bytes_total | Number of bytes transmitted on a network interface, in bytes |
| transmit_packets_total | Number of packets transmitted on a network interface |
| transmit_errors_total | Number of packet transmit errors on a network interface |
| transmit_drops_total | Number of packet transmit drops on a network interface |

This repository provides code for a Prometheus metrics exporter for libvirt. This exporter connects to any libvirt daemon and exports per-domain metrics related to CPU, memory, disk and network usage. By default, this exporter listens on TCP port 9000 and use libvirtd api by unix remote api (just listen libvirtd sock)
after build ，you can to see hlep
./prometheus-libvirt-exporter -h
Usage of ./prometheus-libvirt-exporter:
-libvirt.uri string
Libvirt URI from which to extract metrics. (default "/var/run/libvirt/libvirt-sock")
-web.listen-address string
Address to listen on for web interface and telemetry. (default ":9000")
-web.telemetry-path string
Path under which to expose metrics. (default "/metrics")
