    Steps to reproduce

Let's create some resources and fill it with data:

#!/usr/bin/env bash
set -e

METRIC=test
PROJECT_ID=$(uuidgen)

RES_COUNT=3
    until [ $RES_COUNT -eq 0 ]; do
        RES_ID=$(uuidgen)
        gnocchi resource create --type generic -a project_id:${PROJECT_ID} -n ${METRIC} ${RES_ID}
        RES_COUNT=$[RES_COUNT-1]
    done

RESOURCES=$(gnocchi resource list -t generic -f value -c id)

# MAX = 86400/(5*60)

MAX=288

for R in ${RESOURCES}; do
    START=$(date +%s -d '2 days ago 00:00')
    START=$[START-120]
    C=0
    while [ ${C} -lt ${MAX} ]; do
        C=$[C+1]
        START=$[START+300]
        # echo $C : $START : ${R}
        gnocchi measures add --resource-id ${R} -m ${START}@${RANDOM} ${METRIC}
    done
done
# --------------------------------------------------------------------------

it works excellent

stack@devstack:/opt/stack$ gnocchi resource list -t generic -c id -c project_id

Excelent!

check aggregation resample throughout resources in project_id:

stack@devstack:/opt/stack$ gnocchi measures aggregation -m test \

Marvelous!

Let's create one more resource:

stack@devstack:/opt/stack$ gnocchi resource create --type generic -a project_id:a52ba4f1-07a1-4c77-8cf6-2cf48b22b249 -n test $(uuidgen | sed -e 's/-.\{4\}-/-BAAD-/g')
