Help for Real Time Poller
The Real Time Poller function consists of the following:
Real Time Poller Window
The Real Time Poller window enables you to view a real-time graph of the performance data of polling objects within hosts that you specify. Data for multiple polling objects, from multiple hosts, can be combined on a single graph. You can also specify the polling interval for the polling objects and the maximum number of points that appear on the graph.
Notes: |
- Open the Remote Ping dialog box and poll the node from z/OS UNIX System Services before polling the node with the Real Time Poller. This enables you to see the status of the node.
- During run time, the Real Time Poller creates the following configuration directory:
%bindir%\..\generic_unix\TDS\client\bin\config .
From the config directory, additional directories are created with the same names as the nodes being polled with the Real Time Poller. Therefore, the config directory and all of the sub-directories can be deleted when the Real Time Poller is not running.
- The
defaultRTP.properties file contains additional Java(tm) options.
|
This window consists of the following interactive areas:
- Display buttons
- The buttons at the top left of the Real Time Poller window provide the following functions:
- New Host button
- Specifies a host for which to display polling objects. Clicking this button opens the
Add New Host dialog box which enables you to specify an additional host and view the associated polling objects.
- Max Points button
- Specifies the number of polling points to display on the
Graphing area before they can no longer be viewed. Clicking this button opens the
Change Number of Points dialog box which enables you to specify the maximum number of points to be displayed. This function changes the maximum number of points on the Graphing area for all active polling objects.
Notes: |
- The default for the maximum number of points is 15 points.
- Changing the value for Max Points changes the maximum number of points displayed on the graph for all polling objects that are being displayed and for any that are added to the graph.
|
- Add button
- Adds the polling object that you have specified to the
Polling Object list.
- Selection field
- Displays the polling object you selected from the
Navigation tree. As you select a polling object in the Navigation tree, it is displayed in the Selection field until you add it to the Polling Object list.
- Navigation tree
- A hierarchical structure that shows each host you specified and all the polling objects associated with the host. Clicking on a polling object displays it in the
Selection field.
- Graphing area
- Displays the performance data for the polling objects you specify. This area can graph performance data for multiple polling objects, and multiple hosts, enabling you to compare performance. The graph line for each polling object is a different color. The color of the line for the polling object being graphed in this area corresponds to the color of the polling object as it is listed in the
Polling Object list.
- Polling Object list
- Displays the name and status for each polling object. The status of a polling object can be displayed as
Running...
or Stopped
, for example. To aid in monitoring multiple polling objects, the color of the polling object in this area corresponds to the color of the polling object as it is being graphed in the
Graphing area.
- Status buttons
- The buttons at the bottom of the Real Time Poller window control which polling objects are displayed on the
Graphing area and, therefore, in the
Polling Object list, as follows:
- Start button
- Starts polling a polling object that has been
Stopped.
The state of the polling object is then graphed in the
Graphing area and the status is shown as
Running...
in the
Polling Object list.
- Stop button
- Stops polling an object. Graphing of the polling object in the
Graphing area is stopped and the status of the polling object is listed in the
Polling Object list as
Stopped
. To stop polling an object, select it in the Polling Object list and then click the Stop button. This polling object remains in the Polling Object list and it can be restarted if it is not removed.
- Remove button
- Removes a stopped polling object from the
Graphing area and from the
Polling Object list. To remove a stopped polling object, select it in the Polling Object list and then click the Remove button.
- Interval
- Opens the
Change Polling Interval dialog box. This enables you to set the polling interval, in seconds, for a selected polling object.
- Clear Graph button
- Clears the
Graphing area. The polling objects which are still
Running...
(as displayed in the
Polling Object list) will start graphing again at the polling interval you specified.
Notes: |
- For information about setting up security for the Real Time Poller, refer to the "NetView Commands, Keywords, and Values that Can Be Protected" chapter of the "NetView for z/OS: Security Reference."
- For information about installing the Real Time Poller, refer to the "NetView for z/OS: Installation: Configuring Graphical
Components" book.

Add New Host Dialog Box
The Add New Host dialog box enables you to specify the host that you want to monitor, and to add the host to the
Navigation Tree in the
Real Time Poller.
This dialog box enables you to specify the following:
- Host Name (IP address) entry field
- Specify either a host name or a fully-qualified IP address in this field.
- Community Name entry field
- Specify the community name of the host in this entry field. The default is
public
.
- Polling Interval (seconds) entry field
- Specify the number of seconds to wait between polling for status. The default is 10 seconds.
Note: | If you add a new host and begin polling an object that is already being polled under another host, the new polling object will inherit the polling interval of the existing polling object. For example, if you are polling IP_Packet on host OldHost and add NewHost and want to poll IP_Packet for that host as well, the polling interval for IP_Packet on NewHost will inherit the polling interval of IP_Packet from OldHost. This is the case regardless of the polling interval that you assign to IP_Packet on NewHost.
|
Click one of the following buttons:
- Add
- Open the Real Time Poller for the specified host.
- Cancel
- Close the dialog box without opening the Real Time Poller.
Change Polling Interval Dialog Box
The Change Polling Interval dialog box enables you to change the polling interval for any polling object in the
Real Time Poller window.
This dialog box enables you to specify the following:
- Polling Interval (seconds)
- Specify the time interval, in seconds, between polling the objects for status.
Notes: |
- The default polling interval is 10 (seconds).
- Using the Interval button, you can change the polling interval for one selected polling object at a time.
- Changing the polling interval of an object redraws the display screen and starts the graphing on the display screen over again.
- Click the right mouse button and the Ctrl key to deselect objects (i.e. not select any objects).
|
Click one of the following buttons:
- Change
- Change the polling interval for polling objects in the Real Time Poller.
- Cancel
- Close the dialog box without changing the polling interval.
Change Number of Points Dialog Box
The Change Number of Points dialog box enables you to change the number of points displayed for all polling objects on the Graphing area of the
Real Time Poller window.
This dialog box enables you to specify the following:
- Number of Points
- Specify the number of points being displayed on the Graphical area of the
Real Time Poller window for the polling objects being monitored. The default is 15 points.
Note: | Changing the value for Max Points changes the maximum number of points displayed on the graph for all polling objects that are being displayed and for any that are added to the graph.
|
Click one of the following buttons:
- Change
- Change the number of points being displayed for the polling objects in the Real Time Poller.
- Cancel
- Close the dialog box without changing the number of points.
