HTML / ASP monitor
The HTML/ASP monitor tests a web server to verify it can accept incoming sessions, generate a web page on the server side, and transmit the requested web page to ipMonitor. The requested pages may be static HTML pages or dynamic pages, such as Microsoft Active Server pages, Cold Fusion pages or PHP Hypertext Preprocessor pages.
Use this monitor to:
- Monitor web-based applications for sales and customer service
- Access corporate databases and back-end applications
- Search the delivered page for a specific text string
Additionally, you can use this monitor to ensure that the web server can:
- Communicate with ipMonitor using the HTTP protocol
- Respond within a required number of seconds
- Run server side scripts, ActiveX components, access data sources, and so on to construct the requested web page
- Transmit the requested web page or resource
Create an HTML / ASP monitor
- Click Devices in the toolbar.
- Locate and click the targeted device you want to monitor.
In the toolbar, click Add > Add New Monitor.
- In the Select Monitor menu, click HTML/ASP.
Under Identification, enter information about the monitor.
Enter a name in the Monitor Name field using up to 64 characters. This name will appear in the monitor list, monitor status, log files, and your reports.
You can change this name later, if necessary. ipMonitor does not use this field to internally identify this monitor.
Select Enabled to enable the monitor.
When enabled, the monitor tests the specified resource using the settings you enter under Test Parameters. You can disable the monitor later if required.
- Select Store Monitor Statistics for Recent Activity and Historical Reports to enable this functionality.
Under Test Parameters, enter the monitor testing parameters.
- Enter the IP address or domain name of the server you want to monitor.
- Enter the TCP port number that the targeted resource responds on. The default is TCP port 80.
- Click Select and choose a credential used by ipMonitor to access the resource.
Select a security protocol and any additional options.
Select Use HEAD request to save bandwidth to verify that the website links are valid and accessible. The monitor obtains meta information about the resource identified by the request URI without transferring the body content.
Select Force communication through an HTTP Proxy Server to monitor the HTTP resources through your HTTP proxy server. Before you select this option, ensure that the ipMonitor global Client HTTP Settings selection in System Settings are set up correctly to allow communications with your proxy server.
Select the options for the test results.
- Enter a search string value.
Select whether to fail or succeed if the search text is found.
Under Timing, configure the fields for the monitor testing states.
- In the Maximum Test Duration field, enter the maximum test duration rate (in seconds) that the monitor times out before the test is considered a failure.
In the remaining fields, enter the number of second between each test while the monitor is in an OK state (Up), a failed state while alerts are processed (Down), and a failed state and the maximum number of alerts have been processed (Lost).
In the Lost state, no additional failure alerts are processed. However, a recovery notification is sent if the monitor recovers.
Under Notification Control, complete the fields to determine how many test failures must occur before an alert is sent.
- Enter the number of test failures that occur for each alert before ipMonitor generates an alert for the monitor. The default option is 3.
Enter the maximum number of alerts to send before the monitor enters a Lost state.
The monitor must be assigned to a notification alert to generate an action.
Under Recovery Parameters, complete the fields to indicate the corrective action used to automatically restore a resource using the External Process Recovery, Reboot Server Recovery, or Restart Service Recovery action.
- Enter the Fully Qualified Domain Name (FQDN), NetBIOS, or IP Address of the machine hosting the service that needs a restart or the machine that needs a restart. You can also click Browse to locate and select the machine.
- Select the set of credentials used by the recovery alert. You can select a specific credential to execute recovery alerts that require access to restricted resources, such as Reboot Server, Restart Service, or External Process.
- Select the list of services to restart on the target machine specified in the FQDN/NetBIOS/IP Address field. This field is only required for the Restart Service alert. If a service has dependencies, select all dependent services.
- Click OK.
