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 and or URLs in a server, such as, http://web and so on.

You can perform a content match on these URLs and confirm their availability. Further, for pages that require authentication, you can provide the username and password 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.
