Disable or Enable Monitor Alerts
The Disable or Enable Monitor(s) Alert automatically
enables or disables monitors or monitor groups based on a change of state in
another monitor. This is useful for times when server maintenance or other activities
are being performed that would logically result in
errors for some monitors and cause unnecessary alerts to be generated. This
alert provides a functionality similar to the Depends On feature for building group
dependencies between monitor groups. One important difference is that
monitors disabled by this type of alert are not automatically re-enabled
when the status of the subject monitor or group changes back to the
original state.
Creating a Disable/Enable Alert Definition
Follow the steps below to create a SiteScope Disable/Enable Alert definition.
- Click the Alerts button on the SiteScope main navigation bar at the
top of the SiteScope screen. The Alert Definitions page is displayed.
- Click the Add link in the Alert Actions section below the Alert Definitions
table. The Add Alert selection page is displayed.
- Select the monitor status category that will trigger the alert. For example, select
error for the alert to be triggered when any monitor to be associated with this alert
reports an error condition.
- Select the Disable/Enable Alert in the Alert Type section and click
the Define Alert button. The Define Disable/Enable Alert page is displayed.
- Select the monitors or groups that will trigger this alert using the
Alert Subject(s) menu tree. Complete the Define Disable/Enable Alert form as described in the
section below. When the required selections are made, click the Add Disable/Enable Alert button
to create the alert definition.
Completing the Disable or Enable Monitor(s) Alert Form
Complete each section of the form as described below and then click the
Add or Update button to add the alert.
- Alert Subject(s)
-
Select the groups or monitors that will trigger this alert.
You can select multiple groups and monitors by holding down the
control key while making your selection. The choices include:
All Groups - Select All Groups if you want SiteScope to perform
an action whenever any monitor on this installation returns the
indicated status condition. For example, you would choose this
option if you want SiteScope to page you whenever any monitor
returns an error status.
[group name] - Select a specific group if you want SiteScope to
perform an action whenever any monitor in the selected group
returns the indicated status condition. For example, you would
select the Network group if you wanted SiteScope to page you if
any monitor in the Network group returned an error status.
[group name]: [monitor name] or [group name]:[subgroup name]: [monitor name]
- Select a specific monitor if you want SiteScope
to perform an action only if the selected monitor returns the indicated status
condition. For example, you would choose this option if you wanted SiteScope
to send you e-mail if one specific monitor returned a warning status.
Alternatively, you may select
all groups or multiple groups and then define an alert filter rule in the
Global and Group Alert Filtering section under the
Advanced Options on the lower portion of the page.
- Disable or Enable Monitor(s)
-
Choose whether this alert will act to enable or disable other
monitors. Remember that any monitors disabled by this type of alert
are not automatically enabled after a given period of time;
therefore, if you disable monitors on an error condition, you
should add another Enable Monitors alert to re-enable them.
You can choose any combination of groups and monitors to act
upon from the Targets list - to select multiple items, hold down
the Control key while clicking on additional items.
- When
-
The number of times the alert conditions should be met before
SiteScope executes the action you specified.
Advanced Options
The Advanced Options section presents a number of options for disabling
the alert and define a filter for conditions that should trigger the alert.
Disable Alerts
Use the Disable Alerts alerts section to manually control suppression of this
alert. This can be useful when the the systems being monitored are off-line for
maintenance or if the recipient of the alerts is unavailable for a period of time.
- Enable Alert
-
This check box cancels any disable conditions and makes the
alert active. Select this radio button to override any disable
action on the alert.
- Disable alert permanently
-
Select this radio button to prevent SiteScope from executing
the alert action, even if the conditions are met. Note:
This permanently disables the alert action until this radio
button is cleared.
- Disable alerts for the next time period
-
Select this radio button to immediately prevent SiteScope from
executing the alert action for the time period entered, even if
the conditions are met. The alerts are re-enabled when the time
period expires. This is useful for temporarily turning off
alerts immediately.
- Disable on a one-time schedule from time1 to
time2
-
Select this radio button to prevent SiteScope from executing
the alert action for the time period indicated, even if the
conditions are met. The alerts are disabled at the beginning of
the time period and re-enabled after the time period expires.
This is useful for temporarily turning off alerts during
scheduled maintenance.
Global and Group Alert Filtering
You can use the Global and Group Alert Filtering option to define alerts for a large number of monitors
and then apply a filter so that only certain monitors within the selected list will actually trigger the alert.
See Using SiteScope Alerts
for more information.
- Name Match
-
This option lets you suppress the alert for all associated monitors
except those with a specific text appearing as part of their name.
Enter all or part of the monitor name string you want to use as a
filter criteria. For example, entering the string URL:
will limit this alert to monitors whose name contains the string
"URL:". The match is case sensitive. You can enter a
regular expression in this text box to match
a status string pattern
- Status Match
-
This option lets you suppress the alert for all associated monitors
except those returning a specific status text. Enter a string that
you expect to appear in the status text for the monitor you want to
trigger this alert. For example, if you type timeout in
this box, an alert will only be triggered by a monitor associated
with this alert which also has a status of "timeout."
This match is case sensitive. You can enter a regular expression in this text box to match a status
string pattern
- Monitor Type
-
You can use this option to select a specific monitor type match for the
alert. Select the monitor type within the set of monitors
associated with this alert that should actually trigger the alert.
Select Any Monitor to trigger the alert action for any
monitor type associated with this alert.
