Limiting or Eliminating Renewing Lease Lock Messages

Question

I have an Azure WebJob that runs as a singleton. The console log file ends up recording a lot of "Renewing singleton lock..." messages, because the job is a long-running one.

Is there a way to stop generating those messages, or reduce their frequency? They don't seem to add anything to my process monitoring.

I know I can change the default lock duration in the job configuration settings. But I can only extend it to 60 seconds, from the default 15. While that would presumably reduce the frequency of the messages by a 3/4, I'm interested in seeing if there's a way to eliminate them entirely.

Startup Code

Not much to it, but here it is:

public static void Main(string[] args)
{
    var config = new JobHostConfiguration();
    config.Tracing.ConsoleLevel = TraceLevel.Error;

    if( config.IsDevelopment )
    {
        config.UseDevelopmentSettings();
    }

    JobHost host = new JobHost( config );

    host.RunAndBlock();
}

I'm using Microsoft.Azure.WebJobs 1.1.2, under the net46 framework.

That is a Verbose level trace message, so if you set JobHostConfiguration.Tracing.ConsoleLevel to TraceLevel.Info you won't see those anymore.

I tried Info, as well as Warning, and I still get those console messages. I'm setting the level in program Main(); does it need to be done somewhere in the message processing function? – Mark Olbert Sep 01 '16 at 15:34
Please update your question above to show your startup code and how you're configuring the level. I just tried and it works for me. What version of the SDK are you using? – mathewc Sep 01 '16 at 15:38

Thanx to mathewc asking me to post the configuration code, I realized that calling config.UseDevelopmentSettings() might be overwriting the trace level I'd set.

Moving the trace level setting below the call to UseDevelopmentSettings() solved the problem. No more flurry of messages!
