----------------------------------------

             Summary: CloudStack usage server don't store data to cloud_usa=
ge.cloud_usage correctly
                 Key: CLOUDSTACK-962
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-962
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the defa=
ult.)
          Components: Usage
    Affects Versions: 4.0.0
            Reporter: Ilia Shakitko


We have found strange behavior of CloudStack usage server.

There are two global settings values:
usage.stats.job.aggregation.range 1440
usage.stats.job.exec.time             00:15

Here I will describe how we had determined this problem.
9th of January we=E2=80=98ve generated some traffic, like 10Gb. But 10th of=
 January we didn=E2=80=99t saw records with amount of traffic in cloud_usag=
e.cloud_usage. And we got this values in cloud_usage db only at 11th.

Looks like it works like as written below:

---------January---------------------------------9th----------------10th---=
-----------11th----------12th-----------
(traffic generetad  )                          10Gb              2,5Gb     =
       5Gb          =E2=80=A6
(traffic stored in  usage_db)               0                    0         =
        10Gb        12,5Gb           =E2=80=A6


We changed the value 'usage.stats.job.aggregation.range' to 10 minutes to h=
ave more tests. Here's what we got:

---------Timeline--------------------------------10:00--------------10:10--=
----------10:20--------10:30--------10:40
(traffic generetad  )                          5Gb                 0       =
           2,5Gb       0               0
(traffic stored in  usage_db)               0                    0         =
         5Gb          5Gb           7,5Gb


My colleague Wei Zhou will adds more comments with what we found in CloudSt=
ack source and solution for it.

Will keep updated information about tests and additional info in this threa=
d.
