使用docker部署node-exporter报错failed to retrieve adjtimex stats: operation not permitted

部署命令

docker run -d --name node-exporter -v /proc:/host/proc -v /sys:/host/sys -v /:/rootfs  quay.io/prometheus/node-exporter:v0.18.1 --path.procfs /host/proc --path.sysfs /host/sys --collector.filesystem.ignored-mount-points="^/(sys|proc|dev|host|etc)($|/)"

报错

ERROR: timex collector failed after 0.000081s: failed to retrieve adjtimex stats: operation not permitted" source="collector.go:132

解决

需要给docker添加参数--cap-add=SYS_TIME

https://github.com/prometheus/node_exporter/issues/835

https://github.com/prometheus/node_exporter/blob/master/README.md#using-docker

docker run -d --name node-exporter \
    --cap-add=SYS_TIME \
    -v /proc:/host/proc \
    -v /sys:/host/sys \
    -v /:/rootfs  \
    quay.io/prometheus/node-exporter:v0.18.1 \
    --path.procfs /host/proc \
    --path.sysfs /host/sys \
    --collector.filesystem.ignored-mount-points="^/(sys|proc|dev|host|etc)($|/)"
