The getStatistics method of the System class loads the values of all the specified parameters with the corresponding system statistics.
This method raises exception 1406 if any of the statistic values exceed Max_Integer (this can happen if your JADE system has been up for a long time; that is, the actual number of operations exceeds Max_Integer).
The parameters for the getStatistics method are listed in the following table.
| Parameter | Obtains the number of… |
|---|---|
| committedTransactions | Committed transactions |
| abortedTransactions | Aborted transactions |
| getObjects | getObject operations performed |
| queuedLocks | queuedLock operations performed |
| createObjects | createObject operations performed |
| deleteObjects | deleteObject operations performed |
| updateObjects | updateObject operations performed |
| lockObjects | lockObject operations performed |
| unlockObjects | unlockObject operations performed |
| beginNotifications | beginNotification operations performed |
| endNotifications | endNotification operations performed |
| deliveredNotifications | Notifications that were sent |
| serverMethodExecutions | Methods executed in the server node operations |
The following example shows the use of the getStatistics method.
