Monitoring URLS for Availability

You can configure OpManager to monitor your Web sites. Many business enterprises require continuous monitoring of their Web sites, as the failure of these sites might have an impact on the business.

You can monitor global URLs, such as www.yahoo.com and www.adventnet.com or URLs in a server, such as http://192.168.4.11/index.html, http://web and so on.

You can perform a content match on these URLs and confirm their availability. Further, for pages that require a form submit, such as user name and password, you can provide these details and verify the availability of the next page.

Note: If a proxy server is configured in your network, make sure to provide its details in the Proxy Server Settings page of OpManager. Refer to Configuring Proxy Server Settings for steps to do this. This is required for monitoring any URL in a proxy-enabled LAN.

To configure a global URL monitor, follow the steps given below:

1. Under the Admin tab, click URL Monitors. In this page you can add, edit, and delete the URL monitors.
2. To add a URL monitor, click Add URL.
3. Enter a name to the URL monitor in the URL Monitor name field.
4. Type the URL address to be monitored.
5. Type the Monitoring Interval and the value of Timeout in the respective fields.
6. Enter the Email ID in the Send Alert to field to be notified when this URL goes down.
7. Type the string to be compared with the contents of the monitored Web page.
8. Select between Get and Post, the methods for any HTTP/HTTPS-based URLs. This is required because certain URLs cannot be accessed using a Get request.
9. Type the request parameters and their values in the form <parameter name>=<value>, if any, to know the actual availability of the URL. Note that you can enter only one parameter in a line.
10. Configure the user name and password for authorization. This will be required in the pages where you need to log-on and test the availability of the host.
11. Click Check Now to check the availability of the URL based on the given details. You can verify the correctness of the given details using this instant check.
12. Click OK to add the URL monitor.
