@bhaisaab What are your reasons for saying that @LogLevel(Log4jLevel.Off)
is inappropriate?
By sensitive param/annotation are you referring to the existing @APICommand
annotation params requestHasSensitiveInfo/responseHasSensitiveInfo? The problem
with this approach is that it doesn't tell about the specific field which is
sensitive and so the entire response needs to be searched for sensitive data by
means of regex which is very bad in terms of performance.

> Key: CLOUDSTACK-8485
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8485
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server
> Affects Versions: 4.5.1, 4.6.0
> Reporter: Sowmya Krishnan
> Assignee: Koushik Das

> listAPIs are taking significantly longer than before (4.2.x)
> I tried out few listAPI calls using a simulator set up with ~ 10K VMs and 8K
> Routers. Here are few results:
> listVirtualMachines is taking > 25 sec to return with pagesize set to 50.
> This is in comparison to 2 sec in earlier cases such as 4.2.
> listVolumes with pagesize = 1000 took more than 10 mins and finally times out.
> Further observations show that there are also lot of slow queries being
> logged in catalina.out and in MySQL slow query logs. I am not sure if this
> could be the reason for DB performance getting impacted in turn causing an
> impact on listAPIs too.
> Here's a sample of slow queries from catalina.out:
