'This counter displays the rate at which IL bytes are jitted per second. This counter is not an average over time; it displays the difference between the values observed in the last two samples divided by the duration of the sample interval.'
'This counter displays the total IL bytes jitted since the start of the application. This counter is exactly equivalent to the "Total # of IL Bytes Jitted" counter.'
'This counter displays the total number of methods compiled Just-In-Time (JIT) by the CLR JIT compiler since the start of the application. This counter does not include the pre-jitted methods.'
'This counter displays the percentage of elapsed time spent in JIT compilation since the last JIT compilation phase. This counter is updated at the end of every JIT compilation phase. A JIT compilation phase is the phase when a method and its dependencies are being compiled.'
'This counter displays the peak number of methods the JIT compiler has failed to JIT since the start of the application. This failure can occur if the IL cannot be verified or if there was an internal error in the JIT compiler.'
'This counter displays the total IL bytes jitted since the start of the application. This counter is exactly equivalent to the "# of IL Bytes Jitted" counter.'
'The Name property defines the label by which the statistic or metric is known. When subclassed, the property can be overridden to be a Key property. '
