Avalon Alert Monitor
The Avalon Lancelot suite provides real-time statistical and trend data
allowing IT staff to monitor and manage IP traffic and to maintain the
efficiency and health of infrastructure, system and applications. It can
generate alerts when one of the aspects crosses a threshold (defined in the
Avalon Lancelot console). The Avalon Alert Monitor allows you to integrate these
alerts into the Topaz system, eliminating the need to check manually for the
alerts.
Usage Guidelines
What to monitor
The Avalon Alert Monitor is useful for forwarding alerts
generated by the Lancelot network monitoring suite to Topaz applications.
The Lancelot suite provides real-time statistical and trend data allowing
IT staff to monitor and manage IP traffic and to maintain the efficiency
and health of infrastructure, system and applications.
Each time an alert is generated by the Avalon Lancelot network
management suite, it can be forwarded to Topaz using the SiteScope Avalon Alert
Monitor. While receiving and
forwarding alerts, SiteScope can log the alerts for you, eliminating
the need to check for the alerts generated by the Avalon Lancelot
manually. In addition, you can be notified of warning conditions that
you might have otherwise been unaware of until something more serious
happened. Each time that it runs this monitor, SiteScope checks alerts
that have been received since the last time the monitor ran.
The following are requirements for using the Avalon Alert Monitor to forward
alerts to Topaz:
- The Avalon server needs to be
configured to send traps to the SiteScope server.
Note: The SiteScope Avalon Alert Monitor receives alerts from
Avalon Lancelot suite as SNMP Traps. For that purpose it must have sole
access to UDP port 162 (this is SNMP Trap UDP port). If another application
(including another instance of SiteScope, running, for example, as a
process) uses this port, the Avalon Alert monitor will
report an "Address in use" error while defining the monitor.
However, the Avalon Alert Monitor can share this port with other SiteScope monitors
that must receive SNMP traps.
- 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.
Completing the Avalon Alert Monitor Form
To display the Avalon Alert Monitor Form, either click the Edit link
for an existing Avalon Alert Monitor in a monitor table, or click the add a
Monitor link on a group's detail page and choose the
"Add Avalon Alert Monitor" link.
Complete the items on the Avalon Alert 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 Avalon
Alert entry matched " is chosen, then the monitor triggers alerts for every
matching entry found.
Note: When the Avalon Alert Monitor is
run in the "for each Avalon
Alert 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 Avalon Alerts 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
-
Enter how frequently the monitor should read the application SNMP
Trap. The drop-down list to the right of the text box lets you
specify time increments of seconds, minutes, hours, or days. You
must specify a time increment of at least 15 seconds.
- Title
-
Enter a name for this monitor. This name appears in the Name
text box on the monitor table when you open the group's detail
page. If you don't enter a name, a default name will be
created.
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 Avalon Alert events forwarded to Topaz.
- EMS configuration file path
-
Enter the path to the EMS integration configuration file. The
default location is: SiteScope\ems\Avalon\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 signaled 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 available parameters for checking are:
- matchCount > 0 (the default)
- matches (number of matches)
- lines (number of lines)
- matches/min (number of matches per minute)
- value (first specific value exists)
- value2 (second specific value exists)
- value3 (third specific value exists)
- value4 (fourth specific value exists)
- 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.
