Ilia Shakitko created CLOUDSTACK-962:
----------------------------------------
Summary: CloudStack usage server don't store data to
cloud_usage.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 default.)
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‘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:
---------January---------------------------------9th----------------10th--------------11th----------12th-----------
(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:
---------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 CloudStack
source and solution for it.
Will keep updated information about tests and additional info in this thread.
