Measuring impact time during config reload

I would like to measure the time it takes for pushing the config to memory and read by TMM.

 

 

For example reloading the configuration using "b load" command takes 4 secs. I am interested in finding out the exact duration when traffic gets impacted.

 

 

Is that possible get this IControl APIs that gets SystemStatisticsPerformanceStatisticQuery or TMM Statistics or global IP statistics?

 

 

I found some usage examples of these, but not sure which specific counter/data I should look for.

    Hi there,

     

     

    I think the easiest practical way to determine this would be to make continuous requests to a VIP using a tool like curl or apachebench, reload the config, and measure how long a VIP doesn't respond for. I don't think there will be any statistic on the box which measures the availability (or non-availability) of objects during a configuration load.
