Hi All, I have started one Vm and write some data to its storage.Then i have monitored disk_write_bytes from ceilometer database(table sample) and its working fine, its recorded the data in its volume attributes but when i delete that file and again gone through the smaple table still the value of volume based on the meter( disk_write_bytes ) increasing so i am getting confused. 1) how ceilometer collect the information about deleted data from storage and 2) why volume of disk_write_bytes in sample table increasing even after deletion of data from its storage.

even after every reboot of vms values of volume in sample table of disk_write_bytes, disk_read_bytes, disk_read_request, disk_write_request are increasing.
