Hi Julien, Sorry to bother you.
I am still testing ceilometer now. I am confused about the meter volume in the mongodb. Let's talk about cpu usage. After I create and boot a vm named vm_1, meter data record about cpu usage will be inserted into db in cycle(default 10 minutes). For example,the 'counter_volume' of the first record is '52060000000',and the second one is '123890000000'. 1) '123890000000' nanoseconds means '123.89' seconds or two minutes,it seem like to be 1238.9 seconds actually, is there something wrong ? 2) If I never reboot or suspend vm_1, will the 'counter_volume' of cpu usage record increase all the time ? Just like '8 minutes' -> '18 minutes' -> '28 minutes' ? 3) If I reboot or suspend vm_1, I find that the 'counter_volume' of cpu usage record will count from zero. Just like '8 minutes' -> '18 minutes' -> '28 minutes' [-> '0 minutes'] ->'5 minutes' -> '15 minutes'. Does it mean that 'counter_volume' just represents how long has vm_1 been booted up ? 4) This one is about Web API. I find that "GET /v1/resources/(resource)/meters/(meter)/volume/sum" just return the sum value of all the cpu 'counter_volume', like '8 minutes' + '18 minutes'. Is it reduplicate ? 5) If I want to know how long has vm_1's cpu been used yesterday, how can I do ? It seems like that I have too many questions.. Thank you very much ! ----------------------- Yawei Wu Dalian Hi-Think Computer Technology,Corp. _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
