Issue

  • After configured a ceilometer expiration time to 7 days, Gnocchi never delete old metrics.
  • However I have 259175 ressource store in /var/lib/gnocchi. That's generate a lot of iops.
  • How to clean them ?

    [root@jncloud-controller-1 gnocchi]$ for i in /var/lib/gnocchi/*; do echo $i;done|wc -l
    259175
    
  • Example with an old metrics : More than 4 Mounths ...
