# docker build . -t sysctl_exporter
# docker run -d --net host --pid host sysctl_exporter
# curl http://localhost:9141/metrics
...
sysctl_parameter{param="vm.overcommit_kbytes"} 0
sysctl_parameter{param="vm.overcommit_memory"} 1
sysctl_parameter{param="vm.overcommit_ratio"} 50
...

or use already built image from docker hub

docker run -d --net host --pid host immortalxjo/sysctl_exporter:latest

Format

There are two variants of metrics

one number parameter

net.ipv4.udp_rmem_min = 4096 generate metric sysctl_parameter{param="net.ipv4.udp_rmem_min"} 4096

multiple numbers parameter

net.ipv4.tcp_rmem = 4096 87380 6291456 produce metrics

sysctl_parameter{column="0",param="net.ipv4.tcp_rmem"} 4096
sysctl_parameter{column="1",param="net.ipv4.tcp_rmem"} 87380
sysctl_parameter{column="2",param="net.ipv4.tcp_rmem"} 6.291456e+06
