Machine and Region Windows |
This chapter describes the machine and region windows.
After you add a machine, you can display a window that contains summary information about the system and the regions running on it.
The machine window has two tabs:
The machine window opens and displays the General tab by default. The title bar contains the machine name and port number.
The datapoints on the General tab are:
|
State of the machine. See Machine States. |
The icon and the color of the machine name indicate the state of the system:
A region can have one of the following states, which is denoted by an icon:
The machine window's MTP Regions tab lists each region on a host and a set of datapoints about that region.
1. Double-click the machine name in the list panel.
2. In the machine window, click the MTP Regions tab.
The table of regions is displayed.
3. Select the region whose details you want to view.
4. Click the Show Details box in the lower left corner of the window.
A panel listing the table details in a more readable format is displayed. You can resize this panel by dragging its top slider.
The datapoints on the region window are as follows:
|
Indicates if the region is running. Values are true and false. |
|
|
Total system processor time (CPU) for all transaction processors (in seconds). See System CPU. |
|
|
Current transaction rate per second. See Transaction Rate. |
|
|
Total number of transactions executed. See Transactions Executed. |
|
|
The total number of transaction classes configured for this region. The value includes the two reserved transaction classes KIXADMIN and KIXDFLT. |
|
|
Total user processor time (CPU) for all transaction processors (in seconds). See User CPU. |
|
|
Number of users connected to the region. See Users. |
The System CPU utilization represents the amount of time spent executing system calls on behalf of a given region.
The value is in the format: hh:mm:ss.
The time displayed is not very precise, because it is measured in units of seconds.
This value tells the administrator how much System CPU a region requires to process transactions. If this datapoint and the User CPU datapoint add up to actual wall clock time, the machine's hardware configuration may be saturated. In this case, either application optimization or additional hardware might be required.
The Transaction Rate value shows the average number of transactions executed in a second by a region.
The value is computed as follows:
#Transactions executed (since last update) divided by the Update Interval
This value gives you an idea of a particular region's throughput. This value can be more accurately computed by using a shorter polling interval. However, a shorter polling interval requires substantially more processing overhead.
The value of this datapoint can be influenced by many factors external to the region. For example, a development server's activities will cause a region to run slower than if the region has a dedicated machine.
The Transactions Executed datapoint represents the cumulative total of transactions executed since the region was started.
This value is retrieved directly from Sun MTP.
This value is used to compute the transaction rate for a particular region.
As long as your system is operating properly, and users are performing transactions, this datapoint should continue to increase. When this datapoint stops growing, check to make sure that all the transaction servers are idle and that no one is logged on to the system. If that is not the case, search for hang conditions.
The User CPU datapoint represents the amount of CPU time spent executing application code (not operating system calls) on behalf of a region.
The value is in the format: hh:mm:ss.
The time displayed is not very precise, because it is measured in units of seconds.
This value tells the administrator how much User CPU a region requires to process transactions. If this datapoint and the System CPU datapoint add up to actual wall clock time, a machine's hardware configuration may be saturated. If this is the case, you must either optimize your application or consider adding additional hardware.
The Users datapoint shows the total number of users that are currently logged in to a region.
This number ranges from 0 to the maximum number of users licensed for this region. It goes up and down depending on users logging in and out.
If this number is consistently close to the licensed maximum number of users, you should consider increasing your license since the region will disallow logins once the maximum licensed number is reached.
