Tuxedo Monitor

The SiteScope Tuxedo Monitor allows you to monitor the availability of an BEA Tuxedo server. The error and warning thresholds for the monitor can be set on as many as ten Tuxedo Monitor performance statistics.

Usage Guidelines

Use the Tuxedo Server Monitor to monitor the server performance data for BEA Tuxedo servers. You can monitor multiple parameters or counters with a single monitor instance. This allows you to watch server loading for performance, availability, and capacity planning. Create a separate monitor instance for each Tuxedo server in your environment.

Before you can use the Tuxedo Monitor, there are a number of configuration requirements involving the Tuxedo environment. An overview follows:

If SiteScope is running as a machine in the same domain as the Tuxedo server then SiteScope can connect to the Tuxedo server as a native client. If SiteScope is outside the domain of the Tuxedo server, you will need to install, configure, and enable the Tuxedo Workstation component to allow SiteScope to make requests of the Tuxedo server.
The client and server side workstation component software versions should be the same. Some versions of the client software can work with multiple versions of Tuxedo servers but support information is limited.
If Tuxedo 7.1 or later is installed on both the server you want to monitor and the SiteScope server, more than one Tuxedo server can be monitored at a time. If Tuxedo 6.5 or earlier is used, only one Tuxedo server can be monitored at a time.
If SiteScope is outside the domain of the Tuxedo server, the Tuxedo Workstation client software needs to be installed on the server where SiteScope is running. This is usually is a DLL called libwsc.dll. The address to the application server needs to be specified in the WSNADDR environment variable.
On the server where the Tuxedo application server is running, set the TUXDIR variable to be the TUXEDO installation directory and add the TUXEDO bin directory to the PATH variable.
The following environment variables need to be added to the SiteScope environment:
- %TUXDIR% should be set on the monitoring machine to the <Tuxedo_root_folder>
- <Tuxedo_root_folder>\bin should be added to %PATH% variable

Note: Any environment variables (for example, TUXDIR) should be defined as system variables, not user variables.

Completing the Tuxedo Monitor Form

To display the Tuxedo Monitor Form, either click the Edit link for an existing Tuxedo Monitor in a monitor table, or click the add a Monitor link on a group's detail page and click the Add Tuxedo Monitor link.

After setting up the Tuxedo environment, complete the items on the Tuxedo Monitor Form as follows. When the required items are complete, click the Add Monitor button.

Server

Choose the server you want to monitor. Use the choose server link to view a list of servers or to enter a path name to a server. The server selection page is displayed. Complete this form as follows:

Server: Enter the name or IP address of the server. The address should match that dedicated to the Tuxedo Workstation component (the WSL process). On UNIX servers, enter the full pathname of the applicable server.
Port: Enter the port number for the Tuxedo server. The port number should match the port dedicated to the Tuxedo Workstation component (the WSL process). The default port for the TUXEDO workstation listener is port 65535.
Client Name: Enter an optional client name for the Tuxedo server.
Connection Data: Enter any extra or optional Connection Data to be used for connecting to the Tuxedo server. In some cases this may be a hexidecimal number.
Username: Enter the Username if required to access the Tuxedo server.
Password: Enter the Password if required to access the Tuxedo server.

Counters

Choose the server performance parameters or counters you want to check with this monitor. The table list to the right of this item displays those currently selected for this monitor. Use the choose counters link to bring up the counters selection screen. Check or clear the check boxes on the choose counters screen to select between one to ten counters to monitor on this server. The performance objects and counters available for the Tuxedo Monitor include:

Server	Requests per second Workload per second
Machine	Workload completed per second Workload initiated per second
Queue	Bytes on queue Messages on queue
Workstation Handler (WSH)	Bytes received per second Bytes sent per second Messages received per second Messages sent per second Number of queue blocks per second.

Update every

Select how often the monitor should read the server statistics. The default interval is to run or update the monitor once every 10 minutes. Use the drop-down list to the right of the text box to specify another update interval in increments of seconds, minutes, hours, or days. The update interval must be 15 seconds or longer.

Title

Enter a title text for this monitor. This text is displayed in the group detail page, in report titles, and other places in the SiteScope interface. If you do not enter a title text, SiteScope will create a title based on the host, server, or URL being monitored.

Advanced Options

The Advanced Options section presents a number of ways to customize monitor behavior and display. Use this section to customize error and warning thresholds, disable the monitor, set monitor-to-monitor dependencies, customize display options, and enter other monitor specific settings required for special infrastructure environments. The options for this monitor type are described below. Complete the entries as needed and click the Add or Update button to save the settings.

Disable

Check this box to temporarily disable this monitor and any associated alerts. To enable the monitor again, clear the box.

Verify Error

Check this box if you want SiteScope to automatically run this monitor again if it detects an error. When an error is detected, the monitor will immediately be scheduled to run again once.

Note: In order to change the run frequency of this monitor when an error is detected, use the Update every (on errors) option below.

Note: The status returned by the Verify Error run of the monitor will replace the status of the originally scheduled run that detected an error. This may cause the loss of important performance data if the data from the verify run is different than the initial error status.

Warning: Use of this option across many monitor instances may result in significant monitoring delays in the case that multiple monitors are rescheduled to verify errors at the same time.

Update Every (on error)

You use this option to set a new monitoring interval for monitors that have registered an error condition. For example, you may want SiteScope to monitor this item every 10 minutes normally, but as often as every 2 minutes if an error has been detected. Note that this increased scheduling will also affect the number of alerts generated by this monitor.

Schedule

By default, SiteScope monitors are enabled every day of the week. You may, however, schedule your monitors to run only on certain days or on a fixed schedule. Click the Edit schedule link to create or edit a monitor schedule. For more information about working with monitor schedules, see the section on Schedule Preferences for Monitoring.

Monitor Description

Enter additional information about this monitor. The Monitor Description can include HTML tags such as the <BR> <HR>, and <B> tags to control display format and style. The description will appear on the Monitor Detail page.

Report Description

Enter an optional description for this monitor that will make it easier to understand what the monitor does. For example, network traffic or main server response time. This description will be displayed on with each bar chart and graph in Management Reports and appended to the tool-tip displayed when you pass the mouse cursor over the status icon for this monitor on the monitor detail page.

Depends On

To make the running of this monitor dependent on the status of another monitor or monitor group, use the drop-down list to select the monitor on which this monitor is dependent. Select None to remove any dependency.

Depends Condition

If you choose to make the running of this monitor dependent on the status of another monitor, select the status condition that the other monitor or monitor group should have in order for the current monitor to run normally. The current monitor will be run normally as long as the monitor on which it depends reports the condition selected in this option.

List Order

By default, new monitors are listed last on the Monitor Detail page. You may use this drop-down list to choose a different placement for this monitor.

Setting Monitor Status Thresholds

SiteScope Application Monitors allow you to set multiple threshold conditions to determine the status reported by each monitor. The individual conditions are combined as logical OR relationships so that when one or more of the conditions (for example any of the conditions for Error if) are met the monitor status is set to the applicable condition. If multiple conditions are met for more than one status condition (such as conditions for both error and for warning), the status for the monitor is set to the highest valued condition. Thus a match of an error condition and a warning condition would be reported as an error status, error being the highest value, warning the next highest and good the lowest value.

Error if: Use one or more of the selection boxes in this item to define one or more error conditions for this monitor. Use the drop-down lists in these items to change error threshold(s) relative to the counters you have selected to check with this monitor. After choosing a counter or parameter, use the comparison operator drop-down list to specify an error threshold such as: >= (greater than or equal to), != (not equal to), or < (less than) and enter a comparison value in the box provided. Comparison values should be entered as whole numbers.
Warning if: Use one or more of the selection boxes in this item to define one or more warning conditions for this monitor. Use the drop-down lists in these items to change warning threshold(s) relative to the counters you have selected to check with this monitor. Set these values relative to those you set for the error threshold in the Error if item.
Good if: You can set this monitor to return a good status for certain conditions. You may define those conditions here. Complete this item as you would for the Error if and Warning if items.
