Prism Page Monitor

The Prism Page Monitor watches for reports on Aggregated Page Performance that are issued by Topaz Real User Monitor (formerly known as Topaz Prism). The Topaz Real User Monitor uses SNMP Traps to deliver the information about Aggregated Pages to the Prism Page Monitor.

Usage Guidelines

What to monitor

The Topaz Real User Monitor is used to collect real-time information on real users visiting a Web site. The information includes statistics that are collected on a usage, such as: average server time, average network time, average client time, number of hits, performance threshold, number of hits below the threshold etc. The Prism Page Monitor is able to collect this information and pass it to Topaz Applications for further processing.

Setup Requirements

The following are requirements for using the Prism Page Monitor to forward alerts to Topaz:

Additional software must be installed on the Topaz Real User Monitor. Consult the Topaz Real User Monitor documentation for more information.
The Prism server needs to be configured to send traps to the SiteScope server.
Note: The SiteScope Prism Page Monitor receives alerts from the Topaz Real User Monitor using SNMP Traps. Thus it must have use of UDP port 162 (standard for SNMP Traps). If another application or process on the machine where SiteScope is running has bound this port, the monitor will report an "Address in use" error and the monitor type will be unavailable. However, the Prism Page Monitor can share this port with other SiteScope monitors that are configured on same SiteScope machine.
SiteScope must be registered with a Topaz installation. The SiteScope must have a profile defined in the Topaz installation prior to enabling the registration in the SiteScope interface. In order to verify registration or to re-register SiteScope with the Topaz server, see the Topaz Server Registration page under SiteScope Preferences.
The Prism Page Monitor must be set to synchronize EMS data with Topaz. See the Completing the Prism Page Monitor Form section below for more information.

Additional configuration steps may be necessary to have monitor data reported to the Topaz Alert Log. See the section Reporting Monitor Data to the Topaz Alert Log for information on how to enable reporting to the Topaz Alert Log.

Completing the Prism Page Monitor Form

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

Complete the items on the Prism Page Monitor Form as follows. When the required items are complete, click the Add Monitor button.

Run Alert

Choose the method for running alerts. If "for each Prism Page entry matched" is chosen, then the monitor triggers alerts for every matching entry found.

Note: When the Prism Page Monitor is run in the "for each Prism Page entry matched" alert method, the monitor will never report a status of error or warning, regardless of the results of the content match or even if the target SNMP Trap is not found.

If the "once, after all Prism Pages have been checked" method is chosen, then the monitor counts up the number of matches and triggers alerts based on the Error if and Warning if thresholds defined for the monitor in the Advanced Options section.

Update every

Select how often the monitor should read the application SNMP Trap. 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.

Enable EMS Integration

Check this option to have all detected Prism Page events forwarded to Topaz.

EMS configuration file path

Enter the path to the EMS integration configuration file. The default location is: <SiteScope intstall path>\SiteScope\ems\Prism\main.config.

For more information about format of the file see EMS Generic Alert Probe Configuration.

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.

Error if

Set an error threshold for this monitor. The thresholds are used when the "Run Alerts: once, ..." option is chosen. By default, an error is signalled whenever there is one or more matching events. Select a comparison value from the list, and use the comparison operator list to specify an error threshold such as: >= (greater than or equal to), != (not equal to), or < (less than).

The possible comparison values are:

matches - the number of matches found.
lines - the number of lines processed.
lines/min - the number of lines per minute processed during this monitoring period.
matches/min - the number of matches per minute that occurred during this monitoring period.

Warning if

Set the Warning threshold for this monitor. The default is to generate a warning if SiteScope is unable to read the SNMP Trap. The symbols in the comparison value drop-down list are the same as those for Error if.

Good if

The default is to mark the monitor as good if the SNMP Trap can be read and there are no matches.
