Hi Gordon, please, let me to understand better.... I am collecting only instance metrics: I need to remove data about instances that ah been removed. I could do that with: gnocchi resource list --type instance -c id -f value if the instance has been delete I could:
gnocchi resource delete instance id Does the above procedure remove data either from database or /var/lib/gnocchi directory ? Any suggestion ?
