Subject [jira] [Commented] (CLOUDSTACK-962) CloudStack usage server didn't store data to cloud_usage in correct time
Date Wed, 16 Jan 2013 16:12:13 GMT


Wei Zhou commented on CLOUDSTACK-962:

For (1), I have changed line 1443 in
from timeSinceJob > aggregationDurationMillis to timeSinceJob > aggregationDurationMillis
- 100.
It works well.

I have posted a patch on Review Board for these two problems.

> 9th of January we‘ve generated some traffic, like 10Gb. But 10th of January we didn’t
saw records with amount of traffic in cloud_usage.cloud_usage. And we got this values in cloud_usage
db only at 11th.
> Looks like it works like as written below:

> (traffic generetad  )                          10Gb              2,5Gb            5Gb
> (traffic stored in  usage_db)               0                    0                 10Gb
       12,5Gb           …
> We changed the value 'usage.stats.job.aggregation.range' to 10 minutes to have more tests.
Here's what we got:

> (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 CloudStack source
and solution for it.
> Will keep updated information about tests and additional info in this thread.
