An added piece of information that @vmaheshw sent me separately:
"In terms of debuggability, Warning for minDurationToLogSlowRequest is really useful with V10.5. It helps us in finding the Network issue or the APP issue."

This would be an update to the logging policy in azure core. @alzimmermsft could you give some insight on whether it would be possible to add this?

@JonathanGiles could you also comment on whether we'd be able to bring forward some of the v11 functionality like logging slow requests as a warning?

[JonathanGiles]

Definitely. Open to PRs to enable this.

[vmaheshw]

System.setProperty(BaseConfigurations.AZURE_LOG_LEVEL, "1");

@rickle-msft This is how I'm able to see the logs. Is this the only way?

[rickle-msft]

That is one of the ways currently. @alzimmermsft suggested that there is one other option and can hopefully share it here. I also gather that there are plans to revamp that interface. Logging comes from the core SDK instead of Storage specifically, so I'll have to rely on Alan for more details.

[alzimmermsft]

@vmaheshw There are two ways to set the logging level, either setting a property or using an environment variable. Both will check for BaseConfigurations.AZURE_LOG_LEVEL and the property takes precedence over the environment variable. Is the concern around this on the value that needs to be set or the default logging level?

[kurtzeborn]

Logs can be enabled via the two methods mentioned above. @vmaheshw please re-open this issue if you have further needs or requests regarding this.

@rickle-msft : Any update on the feature to got WARN for slow requests and customize the timer as discussed above. This was present in V10.5

[rickle-msft]

Logging is handled in Azure Core, so I can't say for certain, but from what I'm seeing, it looks like it'll be included in preview 5 (next month) as the goal for preview 4 has been to get as many of the api breaks finished as possible so they are out of the way earlier rather than later
