Monitoring Options

This event monitor provides the following options:

URLs

Enter the URLs to check. Use the format "http://[devicename]/index.html". When the event monitor runs, the "[devicename]" tag will be replaced with the name of each selected network device.

Alert with [Info/Warning/Error/Critical] if the web server cannot be contacted

Use this option to get alerts when the event monitor cannot contact the web server.

Alert based on the HTTP response status code

The options underneath this check box let you specify the alerts you want to receive for different status codes.

Alert with [Info/Warning/Error/Critical] if the status [is/is not] 200 (success)

Use this option to receive alerts if the status is or is not 200, depending on your use case.

Alert with [Info/Warning/Error/Critical] if the status [is/is not] 301 (moved permanently)

Use this option to receive alerts if the status is or is not 301, depending on your use case.

Alert with [Info/Warning/Error/Critical] if the status [is/is not] 401 (unauthorized)

Use this option to receive alerts if the status is or is not 401, depending on your use case.

Alert with [Info/Warning/Error/Critical] if the status [is/is not] 403 (forbidden)

Use this option to receive alerts if the status is or is not 403, depending on your use case.

Alert with [Info/Warning/Error/Critical] if the status [is/is not] 404 (not found)

Use this option to receive alerts if the status is or is not 404, depending on your use case.

Alert with [Info/Warning/Error/Critical] if the status [is/is not] 500 (internal server error)

Use this option to receive alerts if the status is or is not 500, depending on your use case.

Alert with [Info/Warning/Error/Critical] if the status [is/is not] 502 (bad gateway)

Use this option to receive alerts if the status is or is not 502, depending on your use case.

Alert with [Info/Warning/Error/Critical] if the status is any other code

This final option lets you receive an alert of your choice if that status returned is anything other than the previous seven options.

Alert with [Info/Warning/Error/Critical] if the page content contains specified text

With this option enabled, the web server will look for specified text on the web page and alert if it is found. This option is great for detecting error codes and error messages.

Alert with [Info/Warning/Error/Critical] if the page content does not contain specified text

With this option enabled, the web server will look for specified text on the web page and alert if it is not found. It provides a great option to get alerted if a web page is missing information that should be on every page such as a specific piece of title text or a copyright message.

Download the page [count] times and alert based on download times

Use this option to perform timing tests on your web pages.

Alert if the average download time is greater than a specified value

With this option enabled, the event monitor will calculate the average page download time and alert you if it exceeds the values you choose.

Alert if the maximum download time is greater than a specified value

This option is similar to the previous one, but it alerts based on the maximum observed download time instead of the average.

List the download times in each notification

Enable this option to see a list of the download times in all alerts and notifications.

Alert with [Info/Warning|Error|Critical] if the page has changed since the last check

With this option enabled, the event monitor will remember the page content from the previous check and alert you if the content found on the current run is different.

Perform an advanced content check

Use this option to perform custom checks on the web page content using a script that you write in Javascript. The webpage content will be passed as a parameter to the function called HttpContentCheck(). You must modify the script to perform the desired checks and when it is done it must modify the Result parameter. You must set Result.Status to one of "Success", "Warning", "Error" or "Critical". You must also set Result.Text to some text string that will be used for the event text in alerts and notifications. The supplied example text shows how to confirm that the web page has both an opening and closing body tag.

Connect Time Out

Specify a timeout in milliseconds to tell the event monitor how long to wait while establishing a connection to the web server.

Receive Time Out

Specify a timeout in milliseconds that will tell the event monitor how long it should wait to receive the full web page content after it has connected.

Follow HTTP redirects when they are received

In the case where the event monitor receives a redirect response, this option tells the event monitor to follow the redirect and apply the checks to the page it was redirected to.

Save the downloaded page contents to a file

Enable this option to save the downloaded page content to a file. This option can be helpful when testing the option to detect text on the web page. Enter the full path to a file on the FrameFlow server.

Password Protected Pages

User Name and Password For pages that are protected with challenge-response authentication, enter the credentials that the event monitor should use to authenticate with the web server.

Authentication and Security

If you are monitoring password-protected pages, use the "Select Profile" option to specify the credentials that will be used for challenge-response authentication. Otherwise, no authentication is needed.
