抓取kvm指标信息

依赖

libvirt libvirt-go

要求

远程抓取时候kvm打开tcp侦听

抓取指标如下

libvirt_domain_block_stats_read_bytes_total{domain="...",source_file="...",target_device="..."}
libvirt_domain_block_stats_read_requests_total{domain="...",source_file="...",target_device="..."}
libvirt_domain_block_stats_read_total_time{domain="...",source_file="...",target_device="..."}

libvirt_domain_block_stats_flush_total_time{domain="...",source_file="...",target_device="..."}
libvirt_domain_block_stats_flush_requests_total{domain="...",source_file="...",target_device="..."}

libvirt_domain_block_stats_write_bytes_total{domain="...",source_file="...",target_device="..."}
libvirt_domain_block_stats_write_requests_total{domain="...",source_file="...",target_device="..."}
libvirt_domain_block_stats_write_total_time{domain="...",source_file="...",target_device="..."}

libvirt_domain_info_cpu_time_seconds_total{domain="..."}
libvirt_domain_info_maximum_memory_bytes{domain="..."}

docker

Dockerfile2 是原生模式打出来的镜像有1.5G
Dockerfile 是我处理以后的，打出来镜像80M

请开启kvm的tcp连接，端口16509
