获取不到pvc_usage指标 #22

Closed hbzhu closed 2 years ago

hbzhu commented 2 years ago

您好，使用的是阿里云flexvolume，运行的pvc-exporter-0.1.2，block-pvc-scanner获取不到pvc_usage指标，只有pvc_mapping

/dev/vdc 689G 584G 73G 89% /var/lib/kubelet/plugins/kubernetes.io/flexvolume/alicloud/disk/mounts/d-uf634xb8**

进到block-pvc-scanner容器里执行df -h|grep flexvolume ,然后能把完整的路径放出来吗？我看看是不是匹配不到

hbzhu commented 2 years ago

/usr/src/app # df -h |grep flex /dev/vdb 19.6G 2.4G 16.1G 13% /host/var/lib/kubelet/plugins/kubernetes.io/flexvolume/alicloud/disk/mounts/d-uf63jr560**

把block-pvc-scanner的镜像换成这个试试 dockerid31415926/block-pvc-scanner:tmp

hbzhu commented 2 years ago

感谢大佬，已经能获取到pvc_usage 指标数据了

kais271 commented 2 years ago

客气啦

hbzhu commented 2 years ago

(sum without (container,pod,service,namespace,job,instance,endpoint) (pvc_usage)) + on(volumename) group_left(persistentvolumeclaim,mountedby,pod_namespace)pvc_mapping*0 获取不到数据，貌似是volumename="d-uf65cq8kmgh***bha "} 多了空格

kais271 commented 2 years ago

哪个metric的返回多空格？

hbzhu commented 2 years ago

pvc_usage{volumename="d-uf65cq8km*ubha "}
日志显示也是 2021-12-03 07:32:47,427 - block_pvc_scanner - INFO - VOLUME: d-uf6fjo4***y0g2r , USAGE: 0.96

hbzhu commented 2 years ago

是VOLUME: ('d-uf6j297lwv***bap\n 默认带了换行符

hbzhu commented 2 years ago

修改pv=volume.rstrip() ，已经可以了，谢谢大佬
