Post Alerts

The Post Alert submits a CGI POST containing a description of a monitor condition to a CGI script, servlet or other CGI enabled program. This type of alert provides you with a way of sending alert information through a firewall without having to make any security changes.

Use of the SiteScope Post Alert type requires:

HTTP access between the SiteScope server and the server running the CGI script or server
Format and syntax of the CGI POST request to the applicable CGI script or server

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 Post Alert in the Alert Type section and click the Define Alert button. The Define Post Alert page is displayed.
Select the monitors or groups that will trigger this alert using the Alert Subject(s) menu tree. Complete the Define Post Alert form as described in the section below. When the required selections are made, click the Add Post Alert button to create the alert definition.

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.

By default, SiteScope sends a descriptive form submission about the error or warning status returned by a monitor. If you would prefer a specific format, select the desired option from the Template drop-down list. You may add additional templates into the templates.post directory.

When

The number of times the alert conditions should be met before SiteScope executes the action you specified.

Always, after the condition has occurred at least N times - After the condition occurs at least N times, SiteScope executes the action every time the alert conditions are met. Type the minimum number of times the alert conditions must be met in the text box.
Once, after condition occurs exactly N times - SiteScope executes the action once, after the conditions are met for the Nth time. Type the number of times the alert conditions must be met in the text box.
Initial alert X and repeat every Y times afterwards - Executes the alert action after the condition occurs X consecutive times and then repeats the alert every consecutive Y occurences thereafter. For example,if X was set to 3, and Y was set to 4, then the action would be triggered on the 3rd, 7th, 11th, and so forth, occurrences of the condition. Choose this option by selecting the applicable radio button, entering the multiple (E) and the minimum number of times (N) the alert conditions must be met in the text input boxes provided.

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 usethis 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.
