Help for Foxhound 1.3738b

Table of Contents    [RisingRoad]

An alert is a message automatically displayed and/or sent via email whenever one or more target database conditions match user-defined criteria. The Alerts Criteria page lets you specify these criteria for a particular target database. Individual criteria may include a threshold amount and/or a duration or waiting period.

An alert may be issued as soon as a condition is met (e.g. Alert #9), when a threshold has been reached (e.g. Alert #5) or it may include a waiting period such as "for 10 or more recent samples" (e.g. Alert #2).

An all clear is issued when the alert criteria is no longer met. If a waiting period is specified, Foxhound waits for approximately half that time before issuing the all clear.

A cancelled message is issued as soon as some alert criteria is changed or disabled using this page. At that point the alert testing process "starts over"; it doesn't matter what the change is. For example, even if the new alert condition is already met when the change is made, if there is a waiting period it is honored before a new alert is issued.

The Database Monitor must be running for a target database in order for the alerts to be produced for that database.

The DSN: / Connection String: title shows the name of the DSN or Connection String of the target database to which these Alerts Criteria apply.

If the target database GlobalDBId property is set to a non-default value, that value will be shown in (parentheses) after the DSN: or Connection String: title. This makes it easier to tell different remote databases apart in a replicating or synchronizing environment.

The button does two things:

• First, it works just like the button: it saves all the values on this page for use with the current target database.
• Second, it saves the same values as separate "Default Settings" for use later on, whenever you press the .

The button does two things:

• First, it replaces all the values on this page with the separate "Default Settings". If you have never pressed the button then the "Default Settings" are the same as the "Factory Settings".

The Send alert emails checkbox specifies whether or not you want Alert and All Clear emails to be sent.

Use the Email address(es) for Alerts: field to specify one or more email addresses, separated by semicolons, that are to receive the Alert and All Clear alerts.

Click on the Use HTML in emails: checkbox if you want the email alerts to be formatted using HTML.

The Host[:port] for URLs in emails: field may be used to specify where the Foxhound web server is located relative to the computer receiving the emails, so that HTML links pointing to Foxhound History pages from inside the email alerts can find the right web pages. The default is localhost which works if the emails are being received on the same computer that's running Foxhound. If you start Foxhound on some port other than 80, you can specify a value like localhost:12345. If Foxhound is running on a different computer you'll have to change localhost to that computer's domain name or IP address; e.g., xyz.com:12345.
