I have a kubernetes cluster where I am using local path provisioner for creating storage for multiple projects. Basically this provisioner creates subdirecties under already existing root directory on worker nodes. I am looking for a mechanism for collecting disk usage for all subdirectires exists under the root directory from each worker nodes . Filesystem metricset under system module only provides the filesystem usage of the directory mounted on but doesn't provide metrics for disk usage on subdirectories & file level. What do you think about adding this functionality in filesystem metricset?
