Monitor Web Applications Over HTTPS

To configure the Beacon to recognize the Certificate Authority:

Obtain the Certificate of the Web Site's Certificate Authority, as follows:

In Microsoft Internet Explorer, connect to the HTTPS URL of the Web Site you are attempting to monitor.

Double-click the lock icon at the bottom of the browser screen, which indicates that you have connected to a secure Web site.

The browser displays the Certificate dialog box, which describes the Certificate used for this Web site. Other browsers offer a similar mechanism to view the Certificate detail of a Web Site.

Click the Certificate Path tab and select the first entry in the list of certificates as shown in Figure 2-7.

Click View Certificate to display a second Certificate dialog box.

Click the Details tab on the Certificate window.

Click Copy to File to display the Certificate Manager Export wizard.

In the Certificate Manager Export wizard, select Base64 encoded X.509 (.CER) as the format you want to export and save the certificate to a text file with an easily-identifiable name, such as beacon_certificate.cer.

Open the certificate file using your favorite text editor.

The content of the certificate file will look similar to the content shown in .

Update the list of Beacon Certificate Authorities, as follows:

Locate the b64InternetCertificate.txt file in the following directory of Agent Home of the Beacon host:

agent_home/sysman/config/

This file contains a list of Base64 Certificates.

Edit the b64InternetCertificate.txt file and add the contents of the Certificate file you just exported to the top of the file, taking care to include all the Base64 text of the Certificate including the BEGIN and END lines.

Restart the Management Agent.

After you restart the Management Agent, the Beacon detects your addition to the list of Certificate Authorities recognized by Beacon and you can successfully monitor the availability and performance of the secure Web site URL.
