RPM Probes

You gather RPM statistics by sending out probes to a specified probe target, identified by an IP address or URL. When the target receives the probe, it generates responses, which are received by the Services Router. By analyzing the transit times to and from the remote server, the Services Router can determine network performance statistics.

The Services Router sends out the following probe types:

• HTTP GET request at a target URL
• HTTP GET request for metadata at a target URL
• ICMP echo request to a target address (the default)
• ICMP timestamp request to a target address
• UDP ping packets to a target device
• UDP timestamp requests to a target address
• TCP ping packets to a target device

UDP and TCP probe types require that the remote server be configured as an RPM receiver so that it generates responses to the probes.
