An error has occurred while serving metrics:

collected metric "smartctl_device_statistics" { label:<name:"device" value:"/dev/sdb" > label:<name:"model_family" value:"" > label:<name:"model_name" value:"ST4000NM000A-2HZ100" > label:<name:"serial_number" value:"WJG0S0A0" > label:<name:"statistic_flags_long" value:"valid" > label:<name:"statistic_flags_short" value:"V---" > label:<name:"statistic_name" value:"Vendor Specific" > label:<name:"statistic_table" value:"Vendor Specific Statistics" > gauge:<value:0 > } was collected before with the same name and label values

I first annotated this related code about smartctl_device_statistics metrics , compiled again, and temporarily solved the problem.

@ChaoHsupin ... can you maybe write up a PR with the changes you made to fix this?
Or is this issue not even valid anymore?
