How can I increase the Diagnostics overallquotainMB > 4096 using the diagnostics configuration file and development storage?

Question

Hello,

I'm trying to use the diagnostics configuration file (diagnostics.wadcfg) to configure diagnostics from the start. While using development storage I'm unable to increase the overallquotainMB to anything greater than 4096.

When I increase the OverallQuotainMB to anything over 4097 I get an error "Windows Azure Diagnostics Agent has stopped working" and the diagnostics configuration fails to load.

I'm not looking for the programmatic approach towards configuring diagnostics but rather using the configuration file to set this from the start.

<DiagnosticMonitorConfiguration xmlns="http://schemas.microsoft.com/ServiceHosting/2010/10/DiagnosticsConfiguration"
configurationChangePollInterval="PT1M"
overallQuotaInMB="4096">
 <DiagnosticInfrastructureLogs bufferQuotaInMB="256"
  scheduledTransferLogLevelFilter="Verbose"
  scheduledTransferPeriod="PT1M" />
 <Logs bufferQuotaInMB="256"
   scheduledTransferLogLevelFilter="Verbose"
   scheduledTransferPeriod="PT1M" />
 <Directories bufferQuotaInMB="512"
    scheduledTransferPeriod="PT1M">
  <CrashDumps container="wad-crash-dumps" directoryQuotaInMB="128" />
  <FailedRequestLogs container="wad-frq" directoryQuotaInMB="128"/>
  <IISLogs container="wad-iis" directoryQuotaInMB="128" />  
 </Directories>

 </PerformanceCounters>

 </WindowsEventLog>
</DiagnosticMonitorConfiguration>

When the role starts the Diagnostic Store size is set to default 4096MB by default and the VM is configured to have a FIXED quota for folder name C:\Resources\Directory\*.DiagnosticStore. Once VM is configured to have this FIXED quota you cannot change it in any way. If you really want to modify this size then you will need to change the DiagnosticStore  storage size in the CSDEF file as below and redeployed the service:

    <LocalResources>

      <LocalStorage name="DiagnosticStore" cleanOnRoleRecycle="false" sizeInMB="8192" /> ç Setting 8GB DiagnosticStore

    </LocalResources>
