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.manageengine.com.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.

 

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

  1. Go to Admin-> URL Monitor -> Add URL.
  2. Select URL radio button to configure a URL monitor. This is selected by default.
  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 number of times the URL can go down consecutively before raising an alert.
  7. Type the string (max. 250 characters) to be compared with the contents of the monitored Web page in the Match Content filed. Click on the Check Now button to instantly verify the correctness of the given details.
  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. Select the required notification profile type and click Add button to associate it with this monitor.
  12. Click OK to add the URL monitor.
Configuring URL monitors in bulk
For adding multiple URL monitors, you can import the URL monitor parameters through a csv file. The csv file must contain parameters like Monitor name and URL to be monitored. It can also have additional parameters like Monitoring Interval, time out, match content, profile name and device name. Username and password fields can also be added if the URL needs authorization. Make sure you provide the exact header name and follow the same format provided in the sample file.If the values are not provided for the additional parameters in csv file, the default values will be taken.

In the sample file, you can find a field named Device Name. It is used for monitor the URL from that device. The device should be either Servers or Domain Controllers. If this field is added in the csv file, the URL will be directly added to the device snapshot page. The display name of the device in OpManager or fully qualified domain name should be provided in this field.

 To add multiple URL monitors, follow the steps given below:
  1. Go to Admin-> URL Monitor -> Add URL.
  2. Select Import URLs from CSV radio button.
  3. Click on Browse button to import the CSV file.
  4. Configure the General properties.
  5. Click OK to add the URL monitors.
