This test auto-discovers the methods invoked by the GlassFish server, reports the time taken by the server to execute each method, and reveals errors that may have occurred during method execution. When application users complaint of a slowdown, then this test provides the method-level insight that is necessary for troubleshooting the slowdown. With the help of this test, administrators can quickly figure out which method is taking too long to execute and which methods are throwing exceptions often, and will thus be able to zero-in on the root-cause of the application slowdown.

Measurement	Description	Measurement Unit	Interpretation
Total_success_methods	Indicates the number of invocations of this method that were successful during the last measurement period.	Number
Total_errors_methods	Indicates the number of invocations of this method that resulted in errors during the last measurement period.	Number	Ideally, the value of this measure should be 0.
Error_methods_percent	Indicates the percentage of this method's invocations that resulted in errors.	Percent	A very low value is desired for this measure. Too many errors in method execution can adversely impact application performance.
Method_execution_time	Indicates the time taken for this method to execute during the last measurement period.	Secs	A very low value is desired for this measure. A high value is indicative of problems in method execution, which can cause slowdowns in application performance.
Method_statistics	Indicates the number of times this method was invoked in the last measurement period.	Number
