Measurement
Unit |
Interpretation |
| Instantiation_rate
|
This measure
indicates the rate at which the bean objects are instantiated. |
Instances/Sec
|
A sudden increase in the rate of instantiations indicates a
bottleneck on the server. It may be due to greater load on the server
or there might be a loophole in the application.
|
| Destroy_rate
|
Indicates the
rate at which the bean objects are destroyed. |
Instances/Sec
|
A very low value indicates a bottleneck on the server. This might
affect the performance of the application.
|
| Method_call_rate
|
This measure
indicates the rate at which the methods are being processed by the
server. |
Methods/Sec
|
A high value indicates that the server is busy. The detailed diagnosis of this measure, if enabled, provides the instantiation rate, destroy rate, method call rate, average method rate, average create time, and pool size of each of the currently active beans that constitute the monitored bean group.
|
| Avg_method_rt
|
This measure
indicates the average response time of all methods of the remote
interface for this bean. |
Secs
|
A sudden increase in the value of this measure is a sign of overload
on the server.
|
| Avg_create_time
|
Indicates the
average method response time for creates. |
Secs
|
This value should be low for optimal performance of the application
server. The value may go high, if there are more objects in the pool,
which is a sign of overload.
|
| Pool_size
|
Indicates the
average number of objects in the pool. |
Number
|
A large pool size signifies that some of the objects are not being
released by the application.
