Topaz Host Last Connection Time Monitor
The Topaz Host Last Connection Time monitor checks the
last time a Business Process Monitor, SiteScope or Client Monitor Agent contacted the
Topaz Agent Server. The Topaz Watchdog group
automatically configures this monitor type for
a Business Process Monitor, SiteScope or Client Monitor Agent.
The Business Process Monitor is scheduled to connect to Topaz every two minutes.
If the last connection was more than four minutes ago, Topaz Watchdog sets a warning
status for this monitor. If the last connection was more than six minutes ago,
Topaz Watchdog sets an error status.
SiteScope is scheduled to connect to Topaz every 24 hours. If the last
connection was made 24 hours and 10 minutes ago, Topaz Watchdog sets a
warning status for this monitor. If the last connection was 25 hours ago,
Topaz Watchdog sets an error status.
For Client Monitor Agents, Topaz Watchdog always sets an OK status,
since Client Monitor Agents are located on machines that may not be open
all the time, or operating all the time.
Note that you can change the Error and Warning times, if you know that
a specific Agent connects to Topaz at a different frequency than the default one.
For an explanation of the Topaz Watchdog group, see the
Topaz Watchdog help, or open the Topaz Watchdog Settings page, and click
the Help button.

Completing the Topaz Host Last Connection Time Monitor Form
To display the Topaz Host Last Connection Time Monitor Form, either click the Edit link for
an existing Topaz Host Last Connection Time Monitor in a monitor table, or click the add a
Monitor link on a group's detail page and click the
Add Topaz Host Last Connection Time Monitor link.
Complete the items on the Topaz Host Last Connection Time Monitor form as follows. When the required
items are complete, click the Add Monitor button.
- Host Location
- The location from which this agent is reporting. Note that Topaz Watchdog automatically knows the location of this agent according to the agent registration details in Topaz.
- Host ID
- Enter the host ID of this agent in Topaz. Note that Topaz Watchdog automatically knows the Host ID of this agent according to the agent registration details in Topaz.
- Update every
-
Select how often the monitor should check the last connection time from
the specified agent.
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.
