Web Page Monitor

Web Page Monitors are used to monitor HTTP or HTTPS URLs. The ELM Enterprise Manager Server periodically establishes an HTTP connection to the server and port specified. If the response is negative, slower than expected, or if the content has been changed, a variety of notification options can be triggered. Note that multiple Web Page Monitors can be assigned to the ELM Server or to Service Agents. Therefore, you may create Web Page Monitors independent of the number of Agent licenses you have purchased. You must assign the Web Page Monitors to a licensed Agent, however, if you want an Agent to execute the Web Page Monitor.

•

URL - The URL you want to monitor. By default, HTTP communication occurs over TCP port 80. If you are using a different port, you can specify that port as part of the URL. For example, to monitor a web page on www.tntsoftware.com that is listening on port 8080, you would use the following URL: http://www.tntsoftware.com:8080.

•	Warn if QoS slower than __ seconds - You can monitor your Web server's performance. By specifying a value for this field, a warning message will be generated whenever the response from the Web server exceeds the quality of service threshold you specify here.

•	Username - If you must enter a username and password to access the URL listed in the URL field, enter that username in this field.

Note
If you are accessing the URL through a proxy server, this is NOT the username used for Proxy server or firewall authentication. This username is for the Web server that contains the URL being monitored only.

•	Password - The password for the account specified in the Username field.

•	Execute configured Action(s) for every failure - By default, ELM will notify you only the first time the Web server is unavailable. Check this box to have a message sent for each interval that the Web server is unavailable.

•	Warn if content changes - Check this box to cause a warning to be generated if the content of the monitored URL is different from the last time the Web Page Monitor retrieved the URL.

•	Run At Server - Check this box to have the Web Page Monitor always executed on the ELM Server by the ELM Server service account. If you leave the box unchecked, the Web Page Monitor will be executed on the assigned Agents by the Agent's service account.

•	Proxy Server - If the ELM Server or Agent needs to access the monitored URL through a proxy server, enter the name, fully-qualified domain name or IP address of the proxy server in the Proxy Server field. Enter the appropriate port for the proxy server in the Proxy Port field.

•	Failed (Error) 5517 - The web page could not be found or retrieved.

•	Success (Informational) 5518 - The web page was retrieved within the quality of service time period.

•	Quality of Service Warning (Warning) 5519 - The web page was not retrieved within the quality of service time period.

•	Content has changed (Warning) 5520 - The web page was retrieved, but the content has changed.

Displays the Agent Categories to which the Monitor is assigned. Click to select or deselect Agent Categories. Right click to create or edit Agent Categories.

Test any Monitor Item against any Agent capable of running the Item using the drop-down and Test button on this dialog box. Testing a Monitor Item prior to putting it into production validates that the monitor item is configured properly. To test a monitor item:

1.	Select the Agent you wish to test against from the drop-down list.

If the test was successful, you will receive a pop-up indicating this and the option to see detailed results of the test. If the test failed, detailed results of the test will automatically open in Notepad.

Displays the Scheduled Interval and Scheduled Hours settings which control the frequency for the Monitor Item.

Specify the interval at which the monitoring, polling or action is to occur. Depending on the Monitor Item type, Items can be scheduled in interval increments of Seconds, Minutes, Hours and Days. The Scheduled Interval is relative to the top of the hour or top of the minute. For example, if a Scheduled Interval is configured for 10 minutes, the Monitor Item will execute at hh:10:00, hh:20:00, hh:30:00, hh:40:00, hh:50:00, hh:00:00, etc. If a Scheduled Interval is configured for 15 seconds, the Monitor Item will execute at hh:00:15, hh:00:30, hh:00:45, hh:00:00, hh:01:15, etc.

Select the days and/or hours this item is active. By default, the schedule is set to ON for all hours and all days. Mouse clicks toggle squares between ON and OFF. Clicking on an individual square will toggle the active schedule for that hour. Clicking on an hour at the top of the grid, or on a day of the week at the left of the grid will toggle the corresponding column or row. Keyboard equivalents are the arrow keys and the space bar.

This read-only tab displays the properties of the selected object and the values for those properties.
