Microsoft Dynamics CRM 2013/2011 collects useful information about executed plugins which are registered in the Sandbox mode. Approximately, every hour, CRM generates a record of type PluginTypeStatistic. The generated record produces information about the average execution time of each plugin and how many times it failed, killed or successfully executed.
To extract this information, go to Advanced Find and select the Plug-in Type Statistics from the list
Each generated record (of type Plug-in Type Statistic) matches one and only executed plugin. Dynamics CRM monitors the running plugins and updates the Plug-in Type Statistic.
