If you monitor a remote HTTP server, it is useful to configure the HTTP request header for agent HTTP requests.

The http.useragent property defines the value for the User-Agent request header in HTTP requests issued by the vCenter Hyperic agent.

By default, the User-Agent in agent requests includes the vCenter Hyperic agent version, and so changes when the agent is upgraded. Therefore, if a target HTTP server is configured to block requests with an unknown User-Agent, agent requests fail following an agent upgrade.

You can use http.useragent to define a User-Agent value that is consistent across upgrades.

The agent.properties file does not contain this property by default. You must add it to the file.

The default is Hyperic-HQ-Agent/Version For example, Hyperic-HQ-Agent/4.1.2-EE.
